See http://wordpress.clarku.edu/polypeet/projects/trametes/ for a summary (including clades) of A. Justo & D.S. Hibbett. 2011. Phylogenetic classification of Trametes (Basidiomycota, Polyporales) based on a five-marker dataset. Taxon 60(6): 1567-1583, which proposes:

“all members of the trametoid clade should be classified under one single generic name (Trametes).”

Macro: Polypore on dead or live wood, bracket-like without stem, with a cap, upper surface bristly to bald, often zoned; with pores, pore surface white to pale gray, causing a white-rot.
Micro: inamyloid, thin-walled smooth spores.^{1, 4}
