AI-generated description

Omphalotus subilludens is a poisonous fungus that grows in clusters on the ground in wooded areas. In East and Central Texas, it typically fruits from August to November, often near oak trees. The cap is 3-8 cm in diameter, reddish-brown to tan with a velvety texture, and has a distinctive umbilicate (navel-shaped) depression. The gills are decurrent, yellowish-green, and emit a strong, unpleasant odor. It is commonly found in the region's hardwood forests, particularly under live oak and blackjack oak.
