Inonotopsis

Inonotopsis Parmasto 1973, in Dai, Y.C., Fungal diversity, 45, 131-343 (2010)

 

Diagnosis: Basidiocarps annual, resupinate. Pore surface greyish brown to brown. Hyphal system monomitic; generative hyphae simple septate; tissue darkening in KOH. Basidiospores ellipsoid, hyaline, thin-walled, smooth, IKI–, CB–. On angiosperm and gymnosperm wood, causing a white rot. Inonotopsis differs from Inonotus sensu stricto by its hyaline and thin-walled spores. These characters are present in the genus of Onnia, which, however, has sessile to stipitate basidiocarps and robust setae. The phylogenetic position of Inonotopsis is very close to Phellinidium (Kotl.) Fiasson & Niemelä, as shown by Wagner & Fischer (2002) with rDNA sequence data.
