Trametes versicolor

Scientific name:   Trametes versicolor (L.) Lloyd
Derivation of name:  Trametes means "one who is thin;"
versicolor means "of various colors" in reference to the
strongly zonate cap.

L.; Coriolus versicolor (L.) Quel.
Common names:   Turkey tail; Many-zoned polypore.
Phylum:   Basidiomycota
Order:   Polyporales
Family:   Polyporaceae
Occurrence on wood substrate:  Saprobic to weakly
parasitic; clustered, usually overlapping or in fused rosettes
on dead deciduous wood or on dying trees, rarely on
conifer wood; May through December, found year-round.  
Dimensions:  Caps 2.5-8 cm wide and 1-3 mm thick.   
Upper surface: Multicolored with yellowish, orangish,
grayish, bluish, blackish, and reddish-brown concentric
zones; outermost zone usually pale; hairy velvety zones
alternating with almost glabrous zones.
Pore surface: White to yellowish, pores 3-5 per mm.
