What is "panellus"

Panellus is a genus of at least 3 mushroom species of fungi in the Mycenaceae family as defined molecularly. Prior to molecular analyses the generic name had been used for any white-spored pleurotoid with amyloid spores. Unrelated but similar species are now classified in Sarcomyxa and Scytinotus. In older guides and other literature the type species had been placed in either Pleurotus or Panus and the poroid species had been classified in the synonymous genus Dictyopanus or in broadly defined genera like Polyporus ( Polyporaceae) or the more closely allied Favolaschia ( Mycenaceae). The closest molecular allies are Resinomycena and Cruentomycena.
