Fusarium acutatum is a fungus species of the genus Fusarium. Fusarium acutatum can cause gangrenous necrosis on the feet from diabetic patients. Fusarium acutatum produces fumonisin B1, fumonisin B2, fumonisin B3 and 8-O-Methyl-fusarubin.

Spodocybe is a genus of mushrooms in the family Hygrophoraceae. Spodo- means grey and -cybe means head, referring to the grey pileus of the known species. At least two species were formerly classified as species of Clitocybe, as they are clitocyboid mushrooms, bearing a superficial resemblance in morphology to the genus.

Pulvinora is a genus of saxicolous (rock-dwelling) lichens in the family Lecanoraceae. The genus was established in 2021 when DNA studies showed that two species then placed in Lecanora formed a distinct evolutionary lineage. Later work broadened the genus to include three additional species formerly treated in Lecanora, bringing the total number of recognised species to five. Species of Pulvinora form small cushions or thick, warty crusts on rock, and they produce black apothecia (fruiting bodies) that start with raised rims but become strongly domed as they mature.

Cinnabaria is a monospecific fungal genus in the family Teloschistaceae, represented by its sole species, Cinnabaria boliviana. This lichen, found only in Bolivia, is distinguished by its unique genetic signature, as well as morphological characteristics like ascospore size and other traits. Despite its resemblance to certain species from the Caloplaca cinnabarina species complex, Cinnabaria boliviana belongs to a distinct genetic lineage.

Aridoplaca is a fungal genus in the family Teloschistaceae. It is a monotypic genus, containing the single saxicolous (rock-dwelling) squamulose lichen species Aridoplaca peltata, found in South America. This lichen forms vivid orange-red, scaly patches on rocks in the high-elevation deserts of the Andes mountains, where it endures extreme conditions including intense solar radiation and arid climates. It is recognized by its shield-like scales and abundant small, reddish fruiting bodies that give it a wart-like appearance.

Sinuicella is a fungal genus in the family Peltigeraceae. It is a monotypic genus, containing the single species Sinuicella denisonii. Both the genus and species were described as new to science in 2021 by Daphne Stone, Bruce McCune, and Jolanta Miądlikowska. The type specimen was collected by the first author from Polk County, Oregon (USA), where it was found growing on the soil. It is only known to occur in the region of the type locality. The lichen has a minute fruticose (bushy) grey to almost black thallus. The photobiont partner is a member of the cyanobacterial genus Nostoc. The genus

The Neoschizotheciaceae are a family of fungi in the Ascomycota, class Sordariomycetes and order Sordariales. It was introduced in 2021 after molecular analysis of several species of fungi in the order Sordariales. These taxa were found to be similar to taxa found in the families Bombardiaceae, Podosporaceae and Lasiosphaeriaceae, as they had ellipsoidal ascospores, sometimes with appendages, but they were phylogenetically distinct from these three families. Neoschizotheciaceae was established based on Neoschizothecium.

Neoprotoparmelia fuscosorediata is a species of crustose lichen in the family Parmeliaceae. Found in Kenya, it was described as a new species in 2021 by lichenologists Klaus Kalb and André Aptroot. The type specimen was collected in the Nanyuki district of Central Province, where it was found growing on wood in a savannah, at an altitude of 2,050 m (6,730 ft). The specific epithet fuscosorediata refers to the colour of the soredia, which are pale brown to pale ochraceous.

Multisporidea is a fungal genus in the family Malmideaceae. It is monotypic, containing the single species Multisporidea nitida, a corticolous lichen found in Réunion. The lichen has a dull, whitish to pale pinkish-brown thallus that is sometimes bordered by a black hypothallus measuring up to 0.3 mm wide. The lichen is unreactive to standard chemical spot tests, and no lichen substances are detected with thin-layer chromatography.

Lendemeriella aureopruinosa is a species of crustose lichen in the family Teloschistaceae. Found in the Russian Far East, it was formally described as a new species in 2021 by Ivan Frolov, Jan Vondrák, Ulf Arup, Liudmila Konoreva, and Sergey Chesnokov, Lidia Yakovchenko, and Evgeny Davydov. The type specimen was collected on the banks of River Bes-Yuryakh (Yllymakh, Republic of Sakha); here it was found growing on siliceous outcrops in a forest comprising largely birch, alder, and larch trees. The thallus of the lichen ranges in form from an inconspicuous grey film to a more well-developed

Lactifluus rugulostipitatus is a species of mushroom in the family Russulaceae. It was described by James K. Douch, Lachlan Tegart, Luke Vaughan, and Teresa Lebel in 2021. The specific epithet refers to the longitudinally wrinkled stipe that is characteristic of this species. The type locality is near Mount Bundey, Australia.

Lactifluus pseudoflocktoniae is a species of mushroom in the family Russulaceae. It was described by Teresa Lebel, James K. Douch, Lachlan Tegart, and Luke Vaughan in 2021. The specific epithet refers to Lactifluus flocktoniae, to which this species has a strong resemblance. The type locality is near Cann River, Australia.

Lactifluus psammophilus is a species of mushroom in the family Russulaceae. It was described by Teresa Lebel, James K. Douch, and Luke Vaughan in 2021. The specific epithet is Latin (sand-loving), referring to this species' habitat. The type locality is Bunyip State Park, Australia.

Lactifluus pagodicystidiatus is a species of mushroom in the family Russulaceae. It was described by Luke Vaughan, Lachlan Tegart, and James K. Douch in 2021. The specific epithet refers to the presence of some cystidia with shapes resembling a pagoda. The type locality is near the summit of Mount Jersey, Australia.

Lactifluus jetiae is a species of mushroom-forming fungus in the family Russulaceae. It was described by Luke Vaughan, Lachlan Tegart, James K. Douch, and Teresa Lebel in 2021. The specific epithet is a Latinisation of the initials JET, in honour of Jennifer E. Tonkin, who had collected and preliminarily analysed many Australian members of the Russulaceae. The type locality is near the Cann River, Australia.

Lactifluus aurantioruber is a species of mushroom in the family Russulaceae. It originally described by McNabb as Lactifluus clarkeae var. aurantioruber in 1971, named for its reddish-orange colour. Jerry A. Cooper raised this variety to species-rank in 2021, thus acquiring the name Lactifluus aurantioruber. The type locality is Tongariro National Park, New Zealand.

Lactifluus albens is a species of mushroom in the family Russulaceae. It was described by Teresa Lebel, James K. Douch, and Luke Vaughan in 2021. The specific epithet is Latin (bleached), named for the pale cream to buff colouration of basidiomata. The type locality is Dwellingup, Australia.
