Hyorhinomys stuempkei, the hog-nosed shrew rat or Sulawesi snouter, is a species of rodent in the family Muridae, more specifically in the subfamily Murinae, endemic to Sulawesi, Indonesia. It is the only species assigned to the genus Hyorhinomys. This species was discovered in 2015 by Jacob A. Esselstyn and his team, Anang S. Achmadi, Heru Handika, and Kevin C. Rowe. Esselstyn proposed "Sulawesi snouter" as a common name for it. The word "snouter" references the spoof biological text The Snouters: Form and Life of the Rhinogrades, authored by the German zoologist Gerolf Steiner as the fiction

Clionaida is an order of demosponges in the subclass Heteroscleromorpha.

Tachiramantis is a genus of strabomantid frogs. These frogs are endemic to Venezuela and Colombia.

Leucocybe is a small mushroom genus, consisting of 3 named species that were formerly placed in the genus Clitocybe, which they resemble in overall appearance and morphology. They occur in woodlands growing on tree litter or disturbed ground.

Bubarida is an order of demosponges in the subclass Heteroscleromorpha.

Rhizocybe is a genus of fungus in the order Agaricales. The species resemble Clitocybe and grow amongst litter in predominantly coniferous forests.

Atractosporocybe is a mushroom genus in the family Lyophyllaceae in the broad sense. The type species resembles Clitocybe and grows in forests.

The Spiculogloeomycetes are a class of fungi in the subdivision Pucciniomycotina of the Basidiomycota. The class consists of a single order, the Spiculogloeales, together with an additional, unassigned genus, Meniscomyces. Many species are currently known only from their yeast states. Species in the genus Spiculogloea form hyphal states that produce auricularioid (laterally septate) basidia and are parasitic on other fungi.

Diaporthomycetidae is a subclass of sac fungi under the class Sordariomycetes.

Niemelaea is a genus of poroid crust fungi in the family Meruliaceae. The genus was circumscribed by Russian mycologists in 2015 to contain three fungi formerly placed in the genus Ceriporiopsis. Niemelaea fungi are characterized by their crust-like fruit body, large, thin-walled angular pores, and a monomitic hyphal system. Spores made by these fungi are ellipsoid and have refractive contents. The genus is named in honour of Finnish mycologist and polypore specialist Tuomo Niemelä, who described the species Ceriporiopsis balaenae.

Zeroviella is a genus of lichen-forming fungi in the subfamily Xanthorioideae of the family Teloschistaceae. It has eight saxicolous (rock-dwelling) species. Zeroviella was segregated from Rusavskia, a closely related genus, in 2015.

The Naemateliaceae are a family of fungi in the order Tremellales. The family currently contains two genera.

Haloferacales is an order of halophilic, chemoorganotrophic or heterotrophic archaea within the class Haloarchaea. The type genus of this order is Haloferax.

Phylogenetic analyses shows that this family is clearly distinct from other yeast-like families of the Tremellomycetes. The family had six genera in

Bannana is a genus of goblin spiders (family Oonopidae) native to Xishuangbanna prefecture, Yunnan Province, China, where it lives in the leaf-litter of tropical rainforest. There are two known species: Bannana crassispina and B. parvula, both described in 2015. Individuals are pale yellow and unpatterned, and range from around 1.0 to 1.8 mm in body length, with females being slightly larger than males. The eyes are reduced or entirely absent. Known only from a nature reserve in Xishuangbanna, Bannana belongs to a group of Asian goblin spiders known as the "Dysderoides complex", that rang

Geminibasidiomycetes is a class of dikaryotic fungus classified in 2015. Geminibasidiomycetes are heat resistant

The Chlorociboriaceae are a family of "cup fungi" in the order Helotiales, with type genus Chlorociboria. A second genus Brahmaculus, which occurs only in the southern hemisphere (including Chile, New Zealand and Australia), was added in 2021.

Chayamaritia is a genus of flowering plants belonging to the family Gesneriaceae.

Pleurotheciaceae is a family of ascomycetous fungi within the monotypic order of Pleurotheciales in the subclass Savoryellomycetidae and within the class Sordariomycetes.
