Oyster Rollrim
A stemless, fan-shaped relative of the rollrims that grows on dead conifer wood and lumber. It has a tan to yellow-brown, finely velvety cap and dull orange-yellow gills that are often forked and crimped near the point of attachment. Its spore print is yellowish brown. It is a common oyster mushroom look-alike.
Not edible; possibly toxic. It is reported as inedible, and one popular website claims it causes GI upset, but no verified poisoning report was found. Do not eat. It is confused with oyster mushrooms (Pleurotus: white to lilac-gray spore print, no crimped gills, mostly on hardwoods) and, in North America, with chanterelles and the poisonous western jack o'lantern. A spore print (yellowish brown here) separates it from oysters.
