Trechispora is a genus of fungi in the family Hydnodontaceae. Basidiocarps (fruit bodies) are variously corticioid (effused, patch-forming) or clavarioid (branched and coral-like) with spore-bearing surfaces that are variously smooth to hydnoid or poroid. The genus occurs worldwide, though individual species may be localized. Around 50 species have been described to date.[1]

Taxonomy

edit

Trechispora was introduced in 1890 by Finnish mycologist Petter Karsten to describe a fragile, effused fungus with a poroid hymenium and small, spiny basidiospores. His type and only species, T. onusta, is now known to be a synonym of the earlier name Polyporus hymenocystis (= Trechispora hymenocystis).[1] Additional species with a similar micromorphology have subsequently been added to the genus.

 
Trechispora pallescens, the type species of Scytinopogon

The genus Scytinopogon was introduced by Rolf Singer in 1945 to accommodate tropical and subtropical fungi with clavarioid basidiocarps having flattened branches and producing small, spiny to warty basidiospores.[2] Molecular research, based on cladistic analysis of DNA sequences, has however shown that Scytinopogon species are nested within Trechispora [3][1] (which they resemble microscopically) and are consequently not a separate genus but are simply Trechispora species with clavarioid basidiocarps.[1]
