Fungi named in 2013

Auricularia nigricans is a species of fungus in the family Auriculariaceae. Basidiocarps (fruitbodies} are gelatinous, ear-like, and grow on dead wood of broadleaf trees. It is found in southern and eastern Asia, North America, South America and the Caribbean. The name Auricularia polytricha, when used by authors from the Americas, is a synonym of A. nigricans. When used by Asian authors, it likely refers instead to Auricularia cornea.

Protostropharia semiglobata, commonly known as the hemispherical stropharia, the dung roundhead, or the halfglobe mushroom, is an agaric fungus of the family Strophariaceae. The mushrooms have hemispherical straw yellow to buff-tan caps measuring 1–4 cm (0.4–1.6 in), greyish gills that become dark brown in age, and a slender, smooth stem 3–12 cm (1.2–4.7 in) long with a fragile ring. A common and widespread species with a cosmopolitan distribution, the fungus produces mushrooms on the dung of various wild and domesticated ruminants.

Phloeomana speirea, commonly known as the bark bonnet, is a species of fungus in the family Porotheleaceae. It is a bark-inhabiting agaric that produces fuscous-colored to whitish mycenoid to omphalinoid fruit bodies in temperate forests. The fungus was first described to science as Agaricus speireus by Elias Fries in 1815. Scott Redhead transferred it to the new genus Phloeomana in 2013, in which it is the type species.

The Metschnikowiaceae are a family of yeasts in the order Saccharomycetales that reproduce by budding. The family comprises sixteen genera including the type genus Metschnikowia, which is commonly found in floral nectar and dispersed by pollinators on all continents except Antarctica. Originally proposed in 1900 but not validly published until 2013, the family has undergone significant taxonomic revision based on genome-scale studies, leading to the establishment of thirteen new genera in 2024 to better reflect evolutionary relationships. Members are characterized by multilateral budding,

Polycauliona polycarpa is a species of corticolous (bark-dwelling), foliose lichen in the family Teloschistaceae. It was first formally described by German botanist Georg Franz Hoffmann in 1796, as Lobaria polycarpa. It has acquired quite an extensive synonymy in its taxonomic history. In 2013, Patrik Frödén and colleagues transferred it to the genus Polycauliona, as part of a molecular phylogenetics-based restructuring of the family Teloschistaceae. In northern North America, one vernacular name for the species is pin-cushion sunburst lichen.

Glutinoglossum glutinosum, commonly known as the viscid black earth tongue or the glutinous earthtongue, is a species of fungus in the family Geoglossaceae (the earth tongues). First described in 1796 as a species of Geoglossum, the fungus has gone through several changes of genera in its taxonomic history. It was placed in its current genus, Glutinoglossum, in 2013. The smooth, nearly black, club-shaped fruitbodies grow to heights ranging from 1.5 to 5 cm (1⁄2 to 2 in). The head is up to 0.7 cm (1⁄4 in) long, and the stipes are sticky. Several other black earth tongue species are quite

Colletotrichum orbiculare is a plant pathogen of melons and cucumber. It causes the disease anthracnose that can effect curcubits causing lesions on various parts of the plant. It can effect cucumbers, melon, squash, watermelon and pumpkin, especially when the weather is rainy, humid and warm. It can be transmitted by seed as well as soil and survive between crops. It is also spread by feeding cucumber beetles, splashing water, tools and workers. Efforts to control the fungus include the practice of rotating cucurbits out for a 2-year period, planting cultivars with resistance, burning

Gloioxanthomyces vitellinus is a species of agaric (gilled mushroom) in the family Hygrophoraceae. It has been given the recommended English name of glistening waxcap. The species has a European distribution, occurring mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in the glistening waxcap being assessed as globally "endangered" on the IUCN Red List of Threatened Species.

Batrachochytrium salamandrivorans (Bsal) is a pathogenic chytrid fungus that infects amphibian species. Although salamanders and newts seem to be the most susceptible, some anuran species are also affected. Bsal has emerged recently and poses a major threat to species in Europe and North America. It was described in 2013 based on a strain collected from skin tissue of fire salamanders Salamandra salamandra. The pathogen, unidentified up to then, had devastated fire salamander populations in the Netherlands. Molecular phylogenetics confirmed it as related to the well known chytrid B.

Sporastatiaceae is a small family of crustose lichens in the order Rhizocarpales. It contains two genera, Sporastatia and Toensbergia, with a total of five species. Sporastatiaceae was circumscribed in 2013 by Mika Bendiksby and Ernst Timdal.

Pseudogymnoascus destructans (formerly known as Geomyces destructans) is a psychrophilic (cold-loving) fungus that causes white-nose syndrome (WNS), a fatal disease that has devastated bat populations in parts of the United States and Canada. Unlike species of Geomyces, P. destructans forms asymmetrically curved conidia. Pseudogymnoascus destructans grows very slowly on artificial media and cannot grow at temperatures above 20 °C. It can grow around 4 °C to 20 °C, which encompasses the temperatures found in winter bat hibernacula. Phylogenic evaluation has revealed this organism should be

Protostropharia, is a coprophilous agaric fungal genus that produces glutinous, mostly yellowish to yellow brown fruit bodies. Characteristically most form chrysocystidia and rather large, smooth, violaceous basidiospores each with a prominent germ pore (as Stropharia subg. Stercophila). It is differentiated from Stropharia by production of astrocystidia on its mycelium rather than by acanthocytes that Stropharia produces. Phylogenetically, Protostropharia is distinct from Stropharia, Pholiota, and Leratiomyces. Two species, P. luteonitens and P. tuberosa, form pseudosclerotia within the dung

Bettsia is a genus of fungi within the Ascosphaeraceae family. This is a monotypic genus, containing the single species Bettsia alvei. Alvei was first described by Annie Betts and this genus is named for her.

Xylopsora is a genus of lichen-forming fungi, belonging to the family Umbilicariaceae. The genus was established in 2013 when genetic studies showed that several scale-forming (squamulose) lichens previously grouped together were not actually closely related. Species of Xylopsora typically grow on wood, especially old or fire-scarred timber, in forests of the Northern Hemisphere. The genus includes four recognized species, some of which were only recently discovered growing high in tree canopies or detected through environmental DNA techniques.

Thamnolia is a genus of lichens in the family Icmadophilaceae. Members of the genus are commonly called whiteworm lichens. Two species of Thamnolia are used by ethnic peoples of Yunnan Province (China) as a component of purported health-promoting tea: Thamnolia vermicularis, and T. subuliformis.

The Stereopsidales are an order of fungi in the class Agaricomycetes. There is a single family, Stereopsidaceae. It was first described in 2014 to contain the genera Stereopsis, which was until then classified in the order Polyporales, and Clavulicium, which was until then classified in the order Cantharellales. Molecular phylogenetics analysis showed these two genera to belong together in their own order. This order might belong in the subclass Phallomycetidae, but this relationship was poorly supported. The Stereopsidales contain corticoid fungi (Clavulicium and Stereopsis) and stalked,

Glutinoglossum is a genus of six species of earth-tongue fungi in the family Geoglossaceae. The widespread type species, G. glutinosum, is commonly known as the "glutinous earth tongue". G. heptaseptatum is known only from the Czech Republic. Four additional species were described in 2015.

Gloioxanthomyces is a genus of fungi in the family Hygrophoraceae. It was circumscribed in 2013 to contain G. nitidus, and the type species, G. vitellinus. Within the Hygrophoraceae, it is in the tribe Chromosereae and closely related to the genus Chromosera. The generic name derives from the Greek gloio ("glutinous"), xantho ("yellow"), and myces (fungus).

Boletus subalpinus, commonly known as the gasteroid king bolete, is a species of fungus in the family Boletaceae. The species was first described scientifically in 1969 by American mycologists Harry Delbert Thiers and James M. Trappe. It was originally named as a species of Gastroboletus but was found to be in Boletus sensu stricto in a 2013 molecular phylogenetics study. The cap is 5–12 centimetres (2–4+3⁄4 in) wide, buff, convex and then flattening. The flesh is whitish, staining bluish or sometimes pink. The pores are pale then darken and produce no spore print. The stalk is up to 6 cm

Aspergillus felis is a heterothallic species of fungus in the genus Aspergillus which can cause aspergillosis in humans, dogs and cats. It was described for the first time in 2013 after being isolated from different hosts worldwide (North and South America, Europe, Africa, Northeast Asia, and Asia-Pacific). The first host infected was a domestic cat with invasive fungal rhinosinusitis who gave its name to this new Aspergillus as Felis is a genus of cats in the family Felidae. Apsergillus felis was then described in a dog with disseminated invasive aspergillosis and a human patient with

Variospora flavescens is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is a common, widely distributed species and has been recorded in Africa, Asia, Europe, and Macaronesia. It forms large, circular, orange patches up to 10 cm or more across on calcareous stone such as limestone and mortar. First described in 1762, the species has been placed in several genera and was transferred to Variospora in 2013.

Cryptomycota ('hidden fungi'), Rozellida, or Rozellomycota are a clade of micro-organisms that are either fungi or a sister group to fungi. They differ from classical fungi in that they lack chitinous cell walls at any trophic stage in their lifecycle, as reported by Jones and colleagues in 2011. Despite their unconventional phagocytic feeding habits (typical fungi are osmotrophic), chitin has been observed in the inner layer of resting spores, and in immature resting spores for some species of Rozella, as indicated with calcofluor-white stain as well as the presence of a fungal-specific

Phloeomana is a bark-inhabiting agaric fungal genus that produces fuscous-colored to whitish mycenoid to omphalinoid fruit bodies in temperate forests. In addition to the type species Phloeomana speirea, 4 other species, P. alba, P. clavata (= M. thujina, M. phaeophylla), P. hiemalis and P. minutula (formerly Mycena olida), have been placed in the genus. The genus is characterized by nonamyloid smooth, hyaline (translucent) basidiospores and tissues, poorly to moderately differentiated cheilocystidia, diverticulate pileipellis hyphae and general smooth stipe hyphae with scattered

The Kriegeriales are an order of fungi in the subdivision Pucciniomycotina. Most species are known only from their yeast states and can be found in a variety of habitats, ranging from arctic waters to tropical ferns. Hyphal states produce auricularioid (laterally septate) basidia.

Gloioxanthomyces nitidus, commonly known as the shining waxcap, is a species of fungus in the family Hygrophoraceae.

Flavoplaca is a genus of crust-like or scaly lichens in the family Teloschistaceae. It has about 30 species with a mostly Northern Hemisphere distribution. The genus was established in 2013 when genetic studies revealed that these species formed their own distinct evolutionary group, separate from other lichen classifications where they were previously placed. These lichens typically grow on limestone and other calcium-rich rocks, forming distinctive orange to yellow crusty patches that are particularly common in coastal environments and sunny locations. Most species grow directly on rock

Clitocella is a genus of mushroom-forming fungi in the family Entolomataceae. It was circumscribed in 2014 with Clitocella popinalis as the type species. The generic name refers to its similarities and close relationship to the genera Clitopilus and Clitopilopsis; the Latin word cella, meaning "storage place", alludes to "taxa not belonging to Clitopilus or Clitopilopsis". Species have caps with centrally placed stipes; the gills are decurrent, and crowded closely together with a smooth edge. Mushrooms produce a pink spore print. The spores have thin walls (less than or equal to 0.5 μm) that

Bryoplaca is a small genus of lichen-forming fungi belonging to the family Teloschistaceae. Established in 2013 by Ulrik Søchting, Patrik Frödén and Ulf Arup, this small genus comprises just three species that specialise in growing on moss-covered substrates in cold regions of the Northern Hemisphere. These lichens are distinguished by their bright orange fruiting discs that stand out like tiny sunbursts against the mossy cushions they inhabit, earning the genus its name which literally means 'moss-plate'.
