Extract from Wikipedia article: Nigroporus vinosus is a species of poroid fungus in the family Steccherinaceae, and the type species of the genus Nigroporus. Its fruit bodies have brownish caps with tinges of purple or red. The cap underside has a pore surface the same colour as the cap, and minute pores. Nigroporus vinosus has a pantropical distribution. It has been recorded from Africa, North America, Central America, South America, Asia, and Oceania. It is a wood-decay fungus that causes a white rot.
Chinese: 暗紫紅黑孔菌.
Nigroporus vinosus is a species of fungus that belongs to the family Steccherinaceae. It is a wood-decaying fungus that grows on dead trees, particularly hardwoods. In East and Central Texas, Nigroporus vinosus has been found on various host trees, including oak, elm, and willow. The fungus produces annual to biennial, resupinate to effused-reflexed fruiting bodies with a purple to reddish-purple pore surface and a white to cream-colored upper surface. Spores are cylindrical to subcylindrical, measuring 5-7 μm in length. It is relatively common in the region, particularly in areas with abundant deciduous trees and high humidity.
