Article
Full-text available
Two new genera, Basidiopycnis and Proceropycnis, and two new species, Basidiopycnis hyalina and Proceropycnis pinicola, are described. An integrated analysis of morphological, ecological, ultrastructural and molecular data indicates that the new taxa belong to the Atractiellales. Relevant characteristics of the new genera and species are discussed...
Article
Full-text available
An unknown species was isolated from Pinus pinaster infested by Tomicus piniperda (Coleoptera: Scolytidae) in Central Spain. The new taxon is distinguished from other species by morphological features as well as by phylogenetic analysis of aligned sequences of the ITS region of the rRNA operon. Taxonomic implications are discussed, and the new comb...
Article
Full-text available
Despite the recent mycologists’ interest in relationships between gasteroid taxa and agaricoid Basidiomycetes lineages and an intensive debate on the evolution of enigmatic secotioid fungi, systematic studies of the genus Galeropsis have received little attention. Here, the taxonomy of this genus is revised based on morphological and nuclear riboso...

El género Mycena (Pers.) Roussel está ampliamente distribuido por todo el mundo (Kirk et al. 2008), comprende 1.312 especies aceptadas (Kalichman et al. 2020) siendo el tercer género más numeroso dentro del Orden Agaricales. Es un género polifilético (Moncalvo 2000; Oliveira 2021) y se hacen necesarios análisis moleculares para aclarar su compleja...

Glarea lozoyensis is an anamorphic ascomycete that produces pneumocandin B 0 , the starting molecule for the synthesis of the antifungal drug caspofungin (CANCIDAS TM). Glarea lozoyensis was first isolated in 1985 from a water sample from Madrid, Spain. Until now, only the original strain was known, but we have discovered new strains from Argentina...

Hymenoscyphus crataegi is described as new to science. The species was found growing on Crataegus monogyna leaves collected in Spain. It is characterized by homopolar, non-scutuloid ascospores, being acute at both ends, with a high lipid content of large guttules, in combination with asci arising from simple septa. The species is morphologically cl...
Article
Full-text available
A recent collection of an undescribed gymnopoid fungus from typical Mediterranean evergreen forests of western Spain is studied and described. The new species is characterized mainly by its convex and fan shaped white pileus, pruinose stipe and globose basidiospores.

Article
Full-text available
Arrhenia eburnea, an omphalinoid fibulate fungus, is described as a new species. It is characterized by pale basidiomata (white, ivory to yellowish-white), deeply decurrent lamellae, membranal and incrusting pigment of the pileipellis and shape and size of spores. The most similar in outward appearance and macroscopic morphology is the blue-green s...
Article
Full-text available
Psathyrella albofloccosa is described as a new taxon. The abundant material collected was found growing in manured turf, fruiting in large groups. The species is characterized by whitish to pale buff colours of the basidiomata, presence of white conic spines forming the universal veil, capitate cheilocystidia and narrowly elliptical basidiospores.
Article
Full-text available
Mycena pinophila sp. nov. has been found growing on Pinus sylvestris needles. The dark coloured basidiomata, particular habitat and broad and densely diverticulated cheilocystidia characterize the new species. Notes on closely related species are given and a new identification key for Mycena sect. Polyadelphia including all members in the Northern...
Article
Full-text available
Psathyrella lutulenta and P. ornatispora are described as new species, found on the Iberian Peninsula. P lutulenta belongs to sect. Spadiceogrisae, and is characterised by its limophilous habitat, pinkish-grey pileus on drying and sublageniform cystidia. Some holotypes of closed North American taxa, as well as that of the European P. almerensis hav...
Article
Full-text available
Gymnopus castaneus, characterized by its reddish-brown colour and lack of hymenial cystidia, is described as new from Spain. In addition, the new combination Gymnopus brunnescens (Murrill) Villarreal, Heykoop & Esteve-Rav. is proposed.
Article
Full-text available
Hydropus paradoxus var. xerophyticus, characterized by its long cystidia, broad spores and habitat in xerophytic basic pastures with communities of Thymus-Lavandula spp. is described as a new taxon from Spain. In addition, a key to 22 taxa known from Europe is given.
Article

Mycena dunicola is described as a new species belonging to the new section Dunicolae. As a whole, this section shows characters such as the arcuate-decurrent lamellae, negative reaction of the lamellar trama in Melzer's reagent, strongly amyloid spores and presence of pileocysticia. The new species has been found growing on acid, sandy soils in coa...

After the revision of the holotype of Lepista rickenii Singer, we conclude that this is most probably contaxic with L. multiforme (Romell) Gulden. The new taxon L. panaeolus var. paxilloides is proposed and described, found in a mixed mediterranean Quercus ilex-Pinus pinea forest in Spain. This last probably represents, at least in part, some autho...
Article

In this paper, again, three new species of section Fragilipedes are described, Mycena olivaceoflava, M. rubidofusca and M. vicina. Mycena hepatica is a new species of section Rubromarginatae. The circumscription of section Insignes is slightly altered, as a result of which Mycena quinaultensis, M. conspersa, M. mitis and M. corrugans are transferre...
Article
Full-text available
Mycena conicoalba is proposed as a new species belonging to sect. Supinae, growing on bark of Quercus ilex subsp. ballota, in evergreen, Mediterranean forest. It differs from similar species especially by its caulo- and cheilocystidia as well as its characteristic habitat.
Article

Inocybe inexpectata sp. nov., from Spain, is described and illustrated. It is characterized by its small size, brown-argillaceous tinges, strongly decurrent gills, absence of metuloid cystidia, cylindrical to suballantoid spores and a well-developed trichoderm.

Phaeomarasmius gypsophilus is described as a new gypsophilous species found in xerothermic plant communities of Central Spain. It is characterized, apart from its particular habitat, by growing directly on bare soil, and having small fruitbodies (commonly covered by a crystalline crust), chains of ovoid cells in the pileipellis and large basidiospo...
