Taxonomy

The genus Haploporus was circumscribed by mycologists Appollinaris Semenovich Bondartsev and Rolf Singer in 1944 with Haploporus odorus as the type, and only species.[2] The name Haploporus is derived from the Greek words απλόος ("simple"), and πόρος ("pore").[3]

Yu-Cheng Dai and colleagues treated the genus Pachykytospora as a synonym of Haploporus in 2002,[4] and then in subsequent publications.[5][6] Marcin Piątek proposed dividing Haploporus into two sections: sect. Haploporus (cap-like fruit bodies), and sect. Pachykytospora (crust-like fruit bodies).[7] Leif Ryvarden, who adopts a "pragmatic and conservative generic concept" in his 2014 work on European polypores, treats Haploporus as monotypic, containing only H. odorus.[8]

Using Haploporus tuberculosis as a representative generic exemplar, molecular analysis showed Haploporus to be nested within the core polyporoid clade, a phylogenetic grouping of fungi roughly equivalent to the family Polyporaceae.[9]

Description

Haploporus species have an annual to perennial growth habit. They are crust like, with sessile or effused-reflexed (crust like with outside edges extended to form caps) fruit bodies. The hyphal system of Haploporus is dimitic to trimitic; the generative hyphae have clamp connections. The spores are oblong ellipsoid to roughly spherical, ornamented, thick-walled and cyanophilous.[10]

Habitat and distribution

Haploporus fungi cause a white rot.[10]

Species

As of January 2018, Index Fungorum accepts 6 species of Haploporus,[11] retaining Pachykytospora as an independent genus. In a 2016 taxonomic and phylogenetic study of the genus, Chinese scientists accept 13 species, including three newly described species from China.[10]

gollark: Oh, it's not `express.session`.
gollark: ... like that, with express-session, I suppose.
gollark: It's signed or something, it's fiiiiine.
gollark: Because npm is intelligence.
