Rigidoporus sanguinolentus

Rigidoporus sanguinolentus !

Description:

Annual, usually at first in isolated areas, coalescing and becoming effused, up to 5 mm thick, separable or rarely adherent, without distinctive taste or odor; margin concolorous with the pore surface, nearly obsolete or distinct, determinate and rather thick, narrow or rather narrow; pore surface watery-, bluish-, or lemony-white when fresh, often slowly turning reddish where bruised, on drying becoming sordid reddish-brown or sometimes sordid yellowish, the tubes when fresh cartilaginous-crisp or varying to soft and somewhat waxy, drying fragile, up to 4 mm long, pores round, on drying sometimes becoming angular, about (3-) 4-6 per mm, edges thick and entire when fresh, on drying thin, entire to lacerate; context when fresh cartilaginous-crisp, thin, on drying usually becoming hard and appearing resinous, continuing without change into the trama

Habitat:

On rotten wood and bark of angiosperms and gymnosperms from Ontario southward in scattered stations (but abundant in New York) to Florida and Louisiana, in the northern Rockies and along the Pacific Coast from British Columbia to California, in Cuba and Europe; associated rot uncertain, probably white. The astonishing contrast between the fresh and dried condition provides easy identification of typical specimens, but identification of the pale C. expallescens form and thick specimens on the West Coast is difficult. Poria nigrescens is quite similar but differs in becoming much thicker and with a very different growth habit. P. vitrea when fresh has a similar appearance but has no tendency to start as small separate growths which unite, and the associated pocket rot is strikingly different. The type of Polyporus subgelatinosus is sterile and a completely certain disposition is not possible from the available information. Podoporia camshadalica Parm. differs significantly only in having incrusted cystidia

Notes:

Tissue not changing color in KOH; hyphal system monomitic, the context of generative hyphae which are infrequently branched, thin-walled to moderately thick-walled, simple-septate, 4-8 A in diameter; tramal tissue continuous with the context and the hyphae similar except 3-4 µm; in diameter; hymenium 10-13 µm thick; cystidia none; basidia broad-clavate, 11-19 x 7-11 t t; spores hyaline, smooth, IKI -, broadly oval to subglobose, 5-6 (-7) X. 4-6 µm.

isn't it. actually this one is white, when pressed or injured he, discolored red. I found it after i stubled over a halfcovered branched, after i flipped it around, i saw this red color at the underside, it was in contact with ground;i gave it a shock, i suspect it is completly discolored!!
