Remarks (internal) : While Dai (1999) transfered Inonotus dryadeus to Fomitiporia, we prefer to suggest a new genus for I. dryadeus and closely related species. The molecular data of Pseudoinonotus are inconclusive. While it appears as a sister lineage to Phellinus s. str. in the neighbour joining tree (Fig. 1), it is positioned as more closely related to Fomitiporia in the most parsimonious tree (Fig. 2). The monophyly of a Pseudoinonotus}Fomitiporia clade was not rejected by constrained analysis and the Kishino Hasegawa and Wilcoxon signed-ranks tests. However, a number of characters show Pseudoinonotus to be distinct from Fomitiporia : these include the formation of annual fruit bodies and the frequent occurrence of hymenial setae ; in addition, no cystidioid elements are present in Pseudoinonotus.

Description : Pseudoinonotus T. Wagner & M. Fischer, gen. nov.
Fruit bodies annual, becoming encrusted with age; hyphal system monomitic to dimitic; setae present; basidiospores globose to subglobose, hyaline, thick-walled, dextrinoid and cyanophilous. http://www.mycobank.org/...
“Pseudoinonotus is well delimited by its large, thickwalled, globose, hyaline to faintly yellow basidiospores which are positive in Melzer’s reagent and strongly cyanophilous. Hymenial setae are usually frequent and often a crust is developed on the pileus surface. Basidiocarps are annual and the hyphal system is intermediate between monomitic and dimitic. Species of Pseudoinonotus occur both on angiosperms and gymnosperms.” Mycologia November/December 2002 vol. 94 no. 6 998-1016 http://www.mycologia.org/content/94/6/998.full
