Erysiphe species infecting oaks in North America are common and widespread, but compared to Asia and Europe, the taxonomy and phylogeny of North American species is unknown. The present study addresses this dispairity. Comprehensive multilocus phylogenetic analyses, including CAM, GAPDH, GS, ITS, RPB2 and TUB, revealed a high degree of co-evolution...
Powdery mildew is an economically important disease caused by c. 1000 different fungal species. Erysiphe vaccinii is an emerging powdery mildew species that is impacting the blueberry industry. Once confined to North America, E. vaccinii is now spreading rapidly across major blueberry‐growing regions, including China, Morocco, Mexico, and the USA,...
A recent classification framework for Leotiomycetes introduced the novel family Hyphodiscaceae in 2019. However, this endeavor was marred by phylogenetic misinterpretations and a limited comprehension of this fungal group. This resulted in
an inadequate and uninformative diagnostic family description, an incorrect family delineation, and the reclas...
Tympanis species, known plant pathogens primarily inhabiting northern temperate ecosystems, are challenging in diversity and identification. Tympanis vagabunda, was discovered in Sicilia (Italy) on dry twigs and it was a poorly understood species. Upon examination of its type specimen, microanatomical analysis suggested its affiliation with the gen...
This study focuses on the sclerotinioid clade within the Leotiomycetes. Our curiosity was triggered when studying “Poculum sp. 1385” collected by R. P. Korf on Rubus sp. in La Gomera on one of his Mycoflora of Macaronesia expeditions. Korf had indicated that this was a new species, but the collection lacked enough material to establish a type. We c...
The apothecial fungus Ramomarthamyces octomerus sp. nov. is described from specimens collected in Mediterranean climate regions in southern Portugal, Spain (Canary Islands), and the Dalmatian region of Croatia. Presumably saprobic, R. octomerus occurs on intact, decorticated wood of Laurus novocanariensis and Olea europaea. Ascospores are cylindric...
In this contribution, we offer the fifth installment of a series focusing on the phylogeny and taxonomy of powdery mildews. This paper is the second segment evaluating the genus Erysiphe. The first treatment of Erysiphe focused on phylogenetically basal species in the "Uncinula lineage." This research presents a phylogenetic-taxonomic assessment of...
This contribution is part of a series devoted to the phylogeny and taxonomy of powdery mildews, with an emphasis on North American taxa. An overview of Cystotheca species is given, including references to ex-type sequences or, if unavailable, proposals for representative reference sequences for phylogenetic-taxonomic purposes. The new species C. me...
Tympanis species (Leotiales) are plant pathogens distributed mostly in northern temperate ecosystems. The diversity and identity of some species remains unclear. Tympanis vagabunda, found in Sicilia (Italy) on dry twigs of Rosa, Rubus, and Pistacia, is one example of an obscure and poorly known species. During the study of its type specimen in S, w...
In the course of a taxonomic survey on hyphomycetes from the Atacama Desert, four strains of slow-growing, cycloheximide-tolerant dematiaceous fungi were obtained from soil samples. These isolates presented a blastic conidiogenous apparatus and yeast-like budding cells typical of the genus Exophiala. DNA sequence analyses of the internal transcribe...
Novel species of fungi described in this study include those from various countries as follows: Argentina , Colletotrichum araujiae on leaves, stems and fruits of Araujia hortorum . Australia , Agaricus pateritonsus on soil, Curvularia fraserae on dying leaf of Bothriochloa insculpta , Curvularia millisiae from yellowing leaf tips of Cyperus aromat...
Acrogenospora stellata De la Peña-Lastra, A. Mateos & Quijada, sp. nov. Fungal Planet 1436 – Persoonia 49, 2022: 261– 350
In a recently published classification scheme for Leotiomycetes, the new family Hyphodiscaceae was erected; unfortunately, this study was rife with phylogenetic misinterpretations and hampered by a poor understanding of this group of fungi. This manifested in the form of an undiagnostic familial description, an erroneous familial circumscription, a...
The monotypic "bulbilliferous hyphomycete" genus Taxomyces was erected in 1993 for a fungal endophyte isolated from the Yew tree Taxus brevifolia and named Taxomyces andreanae. This fungus was reported to produce the plant-derived anti-cancer drug taxol. The original description of the fungus was not conclusive as to its taxonomic position because...
Botanical gardens have extensive spatial databases of their plant specimens; however,
the fungi occurring in them are generally unstudied. Botanical gardens, with their great plant diversity, undoubtedly harbor a wide range of symbiotic fungi, including those that are plant-pathogenic. One such group of fungi is powdery mildews (Erysiphaceae). The...
Bisporella as typically conceived is a genus of noticeable, bright yellow inoperculate discomycetes. This interpretation of the genus, however, is at odds with Bisporella pallescens, the current name of the type species of the genus; furthermore, the genus has been interpreted as including the unusual species Bisporella resinicola. By comparing mor...
Closed cleistothecia-like ascomata have repeatedly evolved in non-related perithecioid and apothecioid lineages of lichenized and non-lichenized Ascomycota. The evolution of a closed, darkly pigmented ascoma that protects asci and ascospores is conceived as either an adaptation to harsh environmental conditions or a specialized dispersal strategy....
Orbilia xanthostigma, with golden yellow to yellow-orange apothecia and O. leucostigma, with white to very pale rose-lilaceous apothecia, were described by E.M. Fries over 200 years ago. Each of the two taxa, which are not easy to interpret because type material is lacking, was proposed in the past as lectotype of the genus Orbilia. In the here pre...
Hymenobolus agaves has been reported only in Europe and Africa on the American plant Agave americana ( Asparagaceae ). This fungus has never been found in the native range of its host, in arid ecosystems of northern and central Mexico and Texas, USA. It has been suggested to be a pathogen that can kill its host. The fungus grows on succulent leaf b...
Ascospore morphologies provide important characters with which to diagnose and describe taxa in Ascomycota. Ascospore features such as size, shape, color, septation, wall thickness, and guttulation, among others, are provided in identification manuals and descriptions of new species. Yet, by tradition, ascospores are usually described from dead fun...
Since its resurrection, the resinicolous discomycete genus Sarea has been accepted as containing two species, one with black apothecia and pycnidia, and one with orange. We investigate this hypothesis using three ribosomal (nuITS, nuLSU, mtSSU) regions from and morphological examination of 70 specimens collected primarily in Europe and North Americ...
Studies of Trochila (Leotiomycetes, Helotiales, Cenangiaceae) are scarce. Here, we describe two new species based on molecular phylogenetic data and morphology. Trochila bostonensis was collected at the Boston Harbor Islands National Recreation Area, Massachusetts. It was found on the stem of Asclepias syriaca, representing the first report of any...

Orbilia jesu-laurae is a new species of nematode-trapping fungus found on decorticated angiosperm wood in a tropical rainforest in Puerto Rico. The single specimen was studied from fresh apothecia and cultures. Morphology was studied and phylogenetic analysis (rDNA: ITS and LSU) was conducted using both sexual and asexual morphs. Nematodes were add...
Here we show the current knowledge of bryophilous Pezizales in the Canary Islands based on a bibliographic revision. Also, a morpho-taxonomic study of bryophyte-associated fungi of the family Pyronemataceae (Pezizomycetes, Ascomycota) using vital taxonomy was done using collections from Tenerife island. Five species have been identified; two of the...
Geodina salmonicolor is shown to be a synonym of G. guanacastensis , the type and only species of the genus. Comparisons of ITS rDNA sequences of a paratype and two recent collections of G. guanacastensis with published ITS sequences of G. salmonicolor , from the Dominican Republic, show that these are nearly identical. When G. salmonicolor was ere...
Micraspis acicola was described more than 50 years ago to accommodate a phacidium-like fungus that caused a foliar disease of Picea mariana. After its publication, two more species were added, M. strobilina and M. tetraspora, all of them growing on Pinaceae in the Northern Hemisphere, but each species occupying a unique type of host tissue (needles...
The monotypic genus Biatorellina is currently considered a taxonomic synonym of Tryblidiopsis but has an obscure and complicated history. During the revision of the genus Tympanis a syntype of Biatorellina buchsii was fortuitously found and reviewed. Initially our revision led to the hypothesis that B. buchsii could be conspecific with Tympanis con...
A contribution to the knowledge of the genus Calycina in the Canary Islands based on characters of living specimens is presented. Three species are described based on the method of vital taxonomy: Calycina claroflava, C. scolochloae, and C. vulgaris. The last one is a new report for the archipelago. A key, descriptions, illustrations, and notes abo...
Species of Tympanis are well‐known pathogens in Holarctic forests, but we know little about their relationship to other genera in Tympanidaceae. The genus Myriodiscus, remarkable macroscopically and a possible pathogen on bamboo, has a complicated taxonomic history and has not been conclusively placed phylogenetically. Species of Myriodiscus have b...
Triblidiaceae
is a family of uncommonly encountered, non-lichenized discomycetes. A recent classification circumscribed the family to include Triblidium (4 spp. and 1 subsp.), Huangshania (2 spp.) and Pseudographis (2 spp. and 1 var.). The apothecia of these fungi are persistent and drought-tolerant; they possess stromatic, highly melanized coverin...
Fungi in the class Leotiomycetes are ecologically diverse, including mycorrhizas, endophytes of roots and leaves, plant pathogens, aquatic and aero-aquatic hyphomycetes, mammalian pathogens, and saprobes. These fungi are commonly detected in cultures from diseased tissue and from environmental DNA extracts. The identification of specimens from such...
Data on aphyllophoroid fungi in Teide National Park Tenerife are summarized, and 102 species are recorded. Twenty eight species are new to Tenerife, out of which 17 are also new records for the Canary Islands (Athelia pyriformis, Cartilosoma ramentaceum, Ceriporia excelsa, Dendrocorticium lilacinoroseum, Hyphoderma sibiricum, Hyphodermella rosae, H...

Australia, Dothiora corym biae on Corymbia citriodora, Neoeucasphaeria eucalypti (incl. Neoeucasphaeria gen. nov.) on Eucalyptus sp., Fumagopsis stellae on Eucalyptu...
The new genus Aotearoamyces is proposed to accommodate a single species that was repeatedly collected on fallen wood in Nothofagaceae forests of New Zealand and was previously misidentified as a Claussenomyces species. This monotypic genus belongs to Tympanidaceae, a recently erected family in Phacidiales. Aotearoamyces is differentiated from other...
The genus Holwaya was considered to be monospecific until recently because of extensive
species synonymy. Seven species have been described or combined in the genus: H. gigantea, H.
leptosperma, H. mucida (with subsp. nipponica), H. ophiobolus, H. pusilla, H. salicis, and H.
tiliacea. Nowadays most of these taxa are considered to be synonyms of H....
Between December 2012 and May 2017, we conducted a fungal inventory at the Boston Harbor Islands National Recreation Area (BHI) in Massachusetts. We extensively sampled 4 sites (Grape Island, Peddocks Island, Thompson Island, and World's End peninsula) and occasionally visited 4 others for sampling (Calf Island, Great Brewster Island, Slate Island,...
Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity).
Two proposals to am...
A historical worldwide overview of the family Helotiaceae in a broad sense and a revision of its members in the Canary Islands are presented. Nine lignicolous species are described in detail (Ascocoryne cylichnium, A. sarcoides, Chlorociboria aeruginascens, Cyathicula cyathoidea, C. hysterioides, Durella connivens, Pseudohelotium
sordidulum, Stross...
The only hitherto known species of the monotypic genus Tromeropsis, the rarely reported T. microtheca, is redescribed from recent collections on mostly little decayed, grayed, xeric, sun-exposed wood of decorticated trunks and branches of different gymnosperms, exceptionally angiosperms, from different humid regions of central Europe and a dry area...
Knowledge of the relationships and thus the classification of fungi, has developed rapidly with increasingly widespread use of molecular techniques, over the past 10–15 years, and continues to accelerate. Several genera have been found to be polyphyletic, and their generic concepts have subsequently been emended. New names have thus been introduced...
Orbilia beltraniae is a new succulenticolous species from the Canary Islands associated with
scrubs. Phylogenetic analyses based on rDNA sequences of ITS and partial LSU were conducted
determine the relationships of the new species to others in the genus. Macro- and micromorphological,
and ecology data are provided, as well as discussion in respect...
El Herbario Institucional de la Universidad de La Laguna (TFC) constituye el herbario con mayor número de ejemplares de los existentes en los archipiélagos macaronésicos y es uno de los mayores del territorio nacional, donde ocupa el puesto 11 de 56, atendiendo al número de especímenes depositados (Index Herbariorum, 2017). El Herbario TFC presenta...
Four species of the genus Hyaloscypha are presented for the Canary Islands. The study is based on recent collections and 12 previous records. The earlier reports of the genus (Hyaloscypha fuckelii, H. hyalina and H. leuconica) are corrected. All of the reported species are new to the Canarian archipelago (H. aureliella, H. intacta, H. spiralis and...
Based on field work and herbarium studies, a taxonomic revision of the genus Orbilia in the Canary Islands was carried out. Eighteen species of the genus are recognized in the present study. Eight of these are new records for the archipelago (Orbilia cejpii, O. euonymi, O. flavida, O. flavidorosella, O. hesperidea, O. scolecospora, O. vinosa and O....
El manual es una breve guía donde se resumen los métodos empleados para la limpieza de semillas de los cuatro jardines principales de Oasis Park: reserva de plantas autóctonas, jardín de cactus y suculentas, jardín de plantas tropicales y subtropicales y jardín de palmeras. Los métodos están acorde a los medios de los que se disponía durante el 201...
Within a few decades, the family Orbiliaceae Nannf. has undergone important changes. Being earlier placed in the Helotiales Nannf., the family was transferred in 2003 to a new order (Orbiliales Baral, O.E. Erikss., G. Marson & E. Weber) and a new class (Orbiliomycetes O.E. Erikss. & Baral). The major part of the species generally studied have been...
The order Helotiales Nannf. is one of the major groups of apothecial fungi, recognized
within Ascomycota Caval.‐Sm. It is the most diverse order in Leotiomycetes O. E. Erikss. &
Winka, with ca. 2.036 known species in 487 genera. Until recently, there were 13 families
recognized.
After the first comprehensive phylogenetic study of helotialean fungi...
Tremella laurisilvae, a species new to science with a parasitic strategy on Biscogniauxia species, is described from the evergreen laurel forests of Macaronesia. The basidiocarps are macroscopically differentiated by finger-like lobes and brownorange colour. Micromorphological differences with phylogenetically related species are evaluated and its...
A contribution to the knowledge of Cistella and Hyphodiscus in the Canary Islands is presented. Seven species are reported as new to the Canary Islands and to the Macaronesian Region: Cistella dentata, C. grevillei, C. mali, C. hungarica, C. pediformis, C. tenuicula and Hyphodiscus hymeniophilus. Descriptions and illustrations of these species base...
The genus Hyalorbilia in Macaronesia is reevaluated. Four species are new to this region (Hyalorbilia berberidis, H. brevistipitata, H. fusispora and H. polypori). Hyalorbilia inflatula is recircumscribed. The new combination Hyalorbilia polypori (Velen.) Baral & E.Weber is proposed. Hyalorbilia lunata is redefined according to vital taxonomy. A de...
Since Psilocistella quercina was described in 1977, it is considered a doubtful taxon, and therefore
not currently accepted. A bibliographic revision, together with recent studies on collections from France
and the Canary Islands (Spain) are used to provide evidence about its relevance. A provisional key to the
genus is also given.
The name Discinella "meuriesii" is an incorrect spelling of Discinella menziesii. This misspelling has early been rectified, but was commonly overlooked or misunderstood by databases.
The phylogeny of Orbilia aurantiorubra and related species is inferred from ITS sequence data. Orbilia aurantiorubra is redefined according to vital taxonomy. Integrated analyses of molecular and morphological data, and ecological (e.g. substrate) and geographical origin suggest the existence of three new species, which are described in this paper:...

Hi All,
Are you an expertise in getting ancient DNA? Currently I am looking researchers who have expertise in getting DNA from old herbaria collections. Even better if you have it with Ascomycota (Fungi). If so and you like to collaborate with taxonomist to work in projects about systematics, evolution and biogeography, please contact me at lquijull@gmail.com or luis_quijada@fas.harvard.edu and write in the subject of the email "ancient DNA". I am looking for collaboration to learn these technics but also you will be coauthor of the results of this project that start in July.

Hi all, I am doing a paper based on published citations.
We would like to explore biogeographical patterns, ecology and possible introductions of pathogens in ecosystems or host shifting.
Do you know about papers that use similar methods? use citations to explore biogeography or ecology.
Can you recommend me manuscripts about it?

I did not see any information about inoperculate Discomycetes. Is there somebody working Leotiomycetes in this project? This group of fungi is avoided in central-south America, but it is one of the most diverse groups in Ascomycota and their species are saprobes, pathogens, mycorrizal, endophytes and lichenized. With less than 5% of their diversity described, without sequences for the major part of the taxa together with their ecology and diversity stimations, would be a really interesting group to explore in Brazil.
Best wishes,
Luis
I am reviewing the type of one fungi. It was collected in Italy and in the original description the author said it is growing on Pistacia therebinthus, Rosa and Rubus. But the type is constituted by only one branch. So I am trying to figure out what is the plant-host for this fungus.
I did some transverse section and I have some macropictures of the branch (inside the branch is hollow). Are there somebody that can help me? I do not know how to identify wood using anatomy, but maybe somebody can figure out at least at family level. It would be good enough to distinguish between Anacardiaceae and Rosaceae for the host of this fungus.
Hi all,
I am trying to identify a species of the genus Rutstroemia. The sample was collected in Sicilia in a place with Pistacia terebinthus, Rosa sp. and Rubus sp. I do not know the host, it could be any of this three.
I have not been able to find reports of Rutstroemia on the genus Pistacia in Italy or Sicily, maybe there are reports in the mediterranean area that I do not know. The apothecia are brownish-red, around 1 mm, the asci 116-136 x 9.4-12 um and ascospores (7.4)11.3-13.3(15.5) x (3)4-4.5(5.7) um.
I think it could be Rutstroemia fruticeti, maybe an inmature specimen.
This species has been reported several times on Rubus and has similar morphology. If somebody from the mediterranean area, Italy or Sicily can help me I would be glad?
I add some photographs here to know your opinion.
Luis
I am searching for publications about fungal biogeography. I have seen a lot of mycorrhizal fungi examples. But, are there manuscripts that show examples about worldwide distribution patterns of families or groups of fungi that are not mycorrhizal (saprobes, pathogens, endophytes)?
I would like to find manuscripts that show changes in diversity with latitude, vegetation, biomes, etc.
If you know examples, please I would be glad if you sent me an email lquijull@gmail.com or answer my question here.
Thanks in advance
Luis
