Misspellings: Pyncnoporus cinnabarinus
Pileus convex-plane, dimidiate, laterally extended, reviving the second season, 4-6 X 5-10 X 0.5-1 em.; surface azonate, rugulose, pruinose to tomentose, at length glabrous, the color changing from light-orange to cinnabar-red, often fading with age; margin acute, except in large plants, faintly zonate; context floccose, elastic, zonate, reddish; tubes nearly equaling the context, firm, miniatous within, the mouths small, 2-3 to a mm., regular, coccineous, dissepiments rather thin, entire; spores 6-8 X 2-3 p..
Reported by Harkness as occurring on oak in California.
I think Trametes is the best genus for this because if Pycnoporus is recognized, Trametes would need to be split up into several other genera. One should not have to sequence the DNA to figure out the genus of a mushroom if it can be avoided, therefore a larger Trametes is better.
