Fungi named in 2012

Neofavolus alveolaris, commonly known as the hexagonal-pored polypore, is a species of fungus in the family Polyporaceae. It causes a white rot of dead hardwoods. Found on sticks and decaying logs, its distinguishing features are its yellowish to orange scaly cap, and the hexagonal or diamond-shaped pores. It is found in Eurasia and Australia; once thought to be widely distributed in North America, these specimens may belong to Neofavolus americanus.

Entomophthoromycota is a division of kingdom fungi. In 2007, it was placed at the taxonomic rank of subphylum in the most recent revision of the entire fungus kingdom. In 2012, it was raised to the rank of phylum as "Entomophthoromycota" in a scientific paper by Richard A. Humber 2012. Divided into three classes and six families (Ancylistaceae, Basidiobolaceae, Completoriaceae, Entomophthoraceae, Meristacraceae, and Neozygitaceae), it contains over 250 species that are mostly arthropod pathogens or soil- and litter-borne saprobes.

The Xylonomycetes are a class of fungi, which holds 2 orders of Symbiotaphrinales Baral & E. Weber, and Xylonales Gazis & P. Chaverri.

Psilocybe allenii is a species of agaric fungus in the family Hymenogastraceae. Described as new to science in 2012, it is named after John W. Allen, who provided the type collection. It is found in the northwestern North America from British Columbia, Canada to Los Angeles, California, most commonly within 10 miles (16 km) of the Pacific coast. The fruitbodies (mushrooms) grow on rotting wood, especially wood chips used in garden landscaping. The caps of the mushrooms are brown to buff, broadly convex to flattened and have a diameter up to 9 cm (3.5 in), while the white stipes are up to 9 cm

Neofavolus is a genus of four species of polypore fungi in the family Polyporaceae. All four known species of Neofavolus are known from temperate regions and unknown from the tropics. Neofavolus alveolaris, the type species, is widely distributed in the temperate areas of the Northern Hemisphere, while N. cremeoalbidus and N. mikawai are known only from limited areas of eastern Asia. The most recent addition to the genus (transferred from Lentinus), N. suavissimus, is found in North America, Europe, and Japan.

Sutorius is a genus of fungi in the family Boletaceae. Its type species is the widely distributed Sutorius eximius (formerly referred to the genera Boletus, Ceriomyces, Leccinum, and Tylopilus). The Asian Boletus obscureumbrinus, found in Japan and China, was described by Japanese mycologist Tsuguo Hongo in 1968, moved to genus Sutorius in 2016, but then reclassified into genus Neoboletus in 2019. The Australian Sutorius australiensis and the southern Chinese Sutorius subrufus also belong to the genus. The genus name of Sutorius is in honour of Charles Christopher Frost (1805 - 1880), who was

Rossbeevera is a genus of sequestrate (truffle-like) fungi in the family Boletaceae. It was first published in 2012 under the erroneous name Rosbeeva, but was corrected to Rossbeevera in the same issue. The genus was created to contain species formerly placed in Chamonixia, but characterized by having ellipsoid to spindle-shaped spores with 3–5 longitudinal ridges, bluish-green to deep blue fruit body staining reaction, and a thin whitish peridium. The Chinese species R. yunnanensis is the earliest diverging lineage within the genus, and has a close phylogenetic relationship with the bolete

Paralepista flaccida (also called Clitocybe flaccida, Clitocybe inversa, Lepista flaccida and Lepista inversa, or in English tawny funnel cap) is a species of mushroom found across the Northern Hemisphere. It is known to form fairy rings.

Harrya is a fungal genus in the family Boletaceae. It was circumscribed in 2012 to contain the species Harrya atriceps and the type Harrya chromapes. The genus name of Harrya is in honour of Harry Delbert Thiers (1919–2000), who was an American mycologist who studied and named many fungi native to North America, particularly California.

Boletopsis nothofagi is a fungus in the family Bankeraceae. The fungus forms grey fruit bodies that grow in clusters. Like all species of Boletopsis, it has a porous spore-bearing surface on the underside of the cap, but differs from other species of Boletopsis by having characteristics such as elongated spores and a green discoloration when stained with potassium hydroxide. Boletopsis nothofagi is endemic to New Zealand and has a mycorrhizal association with red beech (Nothofagus fusca). It is unknown when exactly the fungus forms its fruit body, but it has so far been found solely in May,

Podoserpula miranda is a rare species of fungus in the family Amylocorticiaceae. The common name for P. miranda is Barbie pagoda. Its specific epithet miranda, is Latin for "admirable." This is a reference to P. miranda's bright pink color. Found in New Caledonia, this species was described in 2012.

Harrya chromapes, commonly known as the yellowfoot bolete or the chrome-footed bolete, is a species of bolete fungus in the family Boletaceae. In its taxonomic history, Harrya chromapes has been shuffled to several different genera, including Boletus, Leccinum, and Tylopilus, and is known in field guides as a member of one of these genera. In 2012, it was transferred to the newly created genus Harrya when it was established that morphological and molecular evidence demonstrated its distinctness from the genera in which it had formerly been placed. The fruit bodies have smooth, rose-pink caps

Atheniella is an agaric fungal genus that produces mostly brightly colored (yellow, pink, orange, or red) mycenoid fruit bodies on small plant debris on forest floors, in fields and bogs. It is not a member of the Mycenaceae, and unlike most Mycenaceae, its basidiospores and tissues do not react with iodine. Atheniella species were most recently classified in Mycena because of their stature. However, they lack amyloid spores and tissues bewildering taxonomists, leading to temporary placements in Hemimycena and Marasmiellus before being phylogenetically excluded from both genera and the

Sutorius eximius, commonly known as the lilac-brown bolete, is a species of fungus in the family Boletaceae. Originally described in 1874 as a species of Boletus, the fungus has also been classified in the genus Leccinum because of the scabers on the stipe, or in Tylopilus because of the color of the spore print. Molecular genetic analysis revealed that the lilac-brown bolete was separate from both of these genera, and merited placement in a new genus. Sutorius was created to contain this bolete and the closely related Australian species S. australiensis. This bolete produces fruit bodies

Morchella importuna is a species of fungus in the family Morchellaceae described from North America in 2012. It occurs in gardens, woodchip beds, and other urban settings of northern California and the Pacific Northwest region of the United States and Canada. The fungus has also been reported from Turkey, Spain, France, Switzerland, Canada and China, although it is unknown whether this is a result of accidental introductions. It is considered a choice edible mushroom. The fruit bodies develop a distinctive ladder-like pattern of pits and ridges on the surface of their conical caps.

Montanelia is a genus of lichen-forming fungi belonging to the large family Parmeliaceae. The genus comprises foliose lichens recognised by its short, narrow lobes with flat to slightly convex edges; a smooth, unperforated outer skin (epicortex); shallow, irregular pseudocyphellae—tiny pores—on the upper surface; slender, cylindrical to spindle-shaped asexual spores (conidia); and a white medulla that contains orcinol depsides.

Borofutus is a fungal genus in the family Boletaceae. Newly described in 2012, it is monotypic, containing the single species Borofutus dhakanus, found in tropical Asia. The generic name Borofutus derives from the Bengali language, and means "large pore", while dhakanus refers to the type locality in Gazipur, Dhaka Division, Bhawal National Park, in Bangladesh. Molecular analysis shows Borofutus to be closely related to Spongiforma.

Cantharellus splendens is a species of fungus in the family Cantharellaceae found in Zambia, Burundi and Tanzania. First described in 1994 as a species of Cantharellus, it was transferred to the new genus Afrocantharellus in 2012.

Cantharellus platyphyllus is a species of fungus in the family Cantharellaceae found in Tanzania. First described in 1966 as a species of Cantharellus, it was transferred to the new genus Afrocantharellus in 2012.

Paralepistopsis acromelalga is a basidiomycete fungus in the Tricholomataceae family. It was formerly classified as Clitocybe acromelalga.

Obba is a genus of three species of poroid, white rot crust fungi in the family Gelatoporiaceae. The genome sequence of the type species, O. rivulosa, was reported in 2016.

Morchella snyderi is a species of fungus in the family Morchellaceae. Described as new to science in 2012, it occurs in the montane forests of western North America, including California, Idaho, Montana, Oregon and Washington. It produces fruit bodies up to 14 cm (5.5 in) tall with ridged and pitted conical caps, and stipes that become pitted in maturity. The color of the morel is yellow to tan when young, but the cap ridges become brown to black in maturity or when dried.

Morchella populiphila is a species of morel fungus (family Morchellaceae) native to northwestern North America. Described as new to science in 2012, its specific epithet refers to its association with black cottonwood (Populus trichocarpa). The morel used to be referred to as Morchella semilibera in western North American field guides until molecular analysis established that to be a strictly European species. M. populiphila occurs in California, Nevada and Oregon. Its fruit bodies grow up to 15 cm (6 in) tall with a ridged and pitted conical cap that attaches about halfway down the stipe.
