Octospora sulcatispora is described as a new species based on five collections from three different locations in Spain (Andalucía, Castilla y León and La Rioja). It is unique due to the sulcate ornamentation of its ascospores, a trait otherwise completely unknown in the bryophilous Pezizales. Furthermore, it is the first species of bryophilous Pezi...

The bryophilous ascomycete Octospora schumacheri is described as a new species based on a collection from Breheimen National Park, Norway. It grows on the complex thalloid liverwort Asterella lindenbergiana and is delineated by stiff hairs covering the receptacle, and broadly ellipsoid ascospores ornamented by prominent irregularly shaped warts wit...

New records of bryoparasitic fungi from Styria are discussed and partly illustrated by macro- and microscopic photographs, and their host bryophytes are given. The following species are reported: Arrhenia lobata, Bryocentria brongniartii, B. metzgeriae, Bryoscyphus rhytidiadelphi, Lamprospora benkertii, L. dicranellae, L. esterlechnerae, L. retispo...

Octospora entosthodontophila, a new smooth-spored bryophilous ascomycete on Entosthodon spp., is described and illustrated based on several collections from Hungary and Spain. The new species infects various species of the terricolous moss genus Entosthodon (Funariaceae). It is one of the first bryoparasitic Pezizales where molecular data confirmed...

Premise: Animal-pollinated plants face a high risk of pollen loss during its transfer. To limit the negative effect of pollen losses by pollen consumption and heterospecific transfer, plant species may adjust and stratify their pollen availability during the day (i.e., "schedule" their pollen presentation) and attract pollinators in specific time...

This paper presents new records and noteworthy data on the following taxa in SE Europe and adjacent regions: red algae Sheathia confusa, parasitic fungus Anthracoidea caryophylleae, mycorrhizal fugus Hydnellum caeruleum, bryoparasitic fungus Octospora erzbergeri, liverwort Cephaloziella baumgartneri, mosses Hamatocaulis vernicosus, Streblotrichum c...

Fungal spores are morphologically highly diverse and are therefore frequently used as diagnostic characters in taxonomy. However, the connection between spore morphology and fungal ecology remains poorly understood. Using phylogenetic comparative analyses, we investigated the putative relationships between four ascospore traits and the dominant pla...

Altogether 206 taxa of bryophytes (21 liverworts and 185 mosses) were recorded during excursions in the Bílé Karpaty Mts (White Carpathians), which are designated Protected Landscape Areas in both the Czech Republic and Slovakia. Among the recorded taxa, two species considered extinct from the bryoflora of the Czech Republic (Fossombronia pusilla a...

Two species of the hepaticolous genus Octosporella (Pyronemataceae, Pezizales) have been recorded from southern Australia on host species that are hitherto unknown as substrates for ascomycetes. Octosporella australis sp. nov. is characterized by large setose ascomata, 3- or 4-spored asci, large ellipsoidal ascospores, 36–65 × 10–15 μm, with unthic...

The results of bryological excursions conducted in the Kokořín area, Central Bohemia in September 2021 are reported. Altogether 192 bryophyte taxa (1 hornwort, 47 liverworts, 144 mosses) were recorded. Two endangered species (Cephaloziella elachista, Scorpidium scorpioides), three vulnerable (Geocalyx graveolens, Drepanocladus polygamus, Pogonatum...

Lamprospora benkertii is described as a new species based on collections from Georgia, Germany, Norway, Slovakia, and Switzerland. It is characterized by orange apothecia without a fimbriate margin, globose ascospores with a seaveri -type ornamentation comprising strong ridges forming a reticulum and a secondary reticulum formed by fine ridges with...

Eckstein, J., Sochorová, Z. & Janošík, L. 2021. Octospora oscarii spec. nov. (Pezizales), a bryophilous ascomycete on the pleurocarpous moss Pseudotaxiphyllum elegans (Hypnales). – Herzogia 34: 286 –298. The bryophilous ascomycete Octospora oscarii is described as a new species based on collections from Central Germany and the Czech Republic. It gr...

The fungal genus Sabuloglossum (earth tongues) was originally described as a monotypic genus based on the species Geoglossum (Microglossum) arenarium. It typically occupies sandy coastal habitats and forms mycorrhizas with Empetrum nigrum (Ericaceae). While studying material from central Europe (Czech Republic, Slovakia, Austria, and Germany), asco...

We discovered that Sarcoleotia globosa (Geoglossomycetes) fruited on the soil of ornamental Erica pot cultures, and its ascospores can germinate on plain agar. These findings prompted us to collect isolates from horticultural and natural environments in Japan and analyze their phylogeny and root colonizing ability. Pure cultures were successfully o...

Lamprospora angularis sp. nov. is described and illustrated from finds in four different Tenerifan localities. The new species is characterised by a combination of the following features: orange to reddish-orange apothecia with a conspicuous fimbriate to shaggy margin, globose ascospores with distinctive regular areolate ornamentation, and infectio...

Lamprospora bulbiformis M.Vega & Janošík, sp. nov., L. gibbosa M.Vega & Janošík, sp. nov. and L. thelespora Martínez-Gil, M.Vega & E.Rubio, sp. nov. are described and illustrated based on live collections from Cyprus, France, Portugal and Spain. Phylogenetic analyses of the concatenated LSU, SSU and EF1-α gene sequences show the studied collections...

During the informal Spring Micromyco 2019 meeting, we tested how newly obtained molecular barcodes of common or poorly known saprotrophic microfungi from more or less targeted collections may be useful for identification and taxonomic studies. Our aim was to obtain DNA sequences of fungi enabling their phylogenetic placement and routine identificat...

The bryophilous ascomycete Octospora svrcekii, belonging to the section Wrightoideae, has so far been reported from only three localities in the world. New collections from Albania, Austria, Croatia, France, Slovakia and Spain have enabled a better understanding of its variability, ecology, distribution and phylogenetic relationships with other tax...

Lamprospora densireticulata sp. nov. is described and illustrated based on fresh collections from Austria, Croatia, Cyprus, France, Germany, Hungary and Spain. Its most important distinguishing characters are subglobose ascospores ornamented with a fine, irregular dense net and the infection on rhizoids of its host moss Aloina ambigua. Two other si...

Significance Biparental care is a rare strategy of offspring protection in insects. We discovered a case of biparental care in bees, in Ceratina nigrolabiata . Benefits of biparental care were identified for both males and females; yet, we found that an extraordinarily high proportion of offspring were unrelated to guard males. This is because fema...

The bryophilous ascomycete Octospora pannosa is presented based on ecological and morphological data from two localities in Germany and Serbia. So far members of the genus Brachytheciastrum or the family Brachytheciaceae have not been reported as host for species of Octospora or related genera. The ascospore ornamentation of the new species consist...

Lamprospora rehmii Benkert, a species of bryophilous Pezizales infecting the moss Pleuridium acuminatum Lindb., is presented from recent collections, one of which is designated as epitype. An illustration from the protologue is designated as lectotype. Sequence data from the LSU and ITS regions have been deposited in GenBank.

Altogether 139 taxa (9 liverworts and 130 mosses) were recorded during the course of four excursions to the region of the Pavlov Hills in South Moravia, including one species new to the Czech Republic (Didymodon sicculus; the identity of another species not recorded in the Czech Republic, Pterygoneurum kozlovii, needs to be confirmed), one species...
