The cap is 3–8 centimetres (1+1⁄4–3+1⁄4 in) wide, greenish-brownish yellow, and slightly moist; it has dark fibrils near the center. The gills and stipe are whitish-yellow, the latter growing up to 10 centimetres (4 in) long.^[4][5] The odor is mild to mealy and the taste mild to unpleasant.^[5]

Similar species

Tricholoma flavovirens is usually larger and fleshier, with more solid yellow gills and stipe and a less fibrillose cap.^[5] Other similar species include Tricholoma arvernense, and T. viridilutescens.^[5]

In North America, it appears on the Northwest coast and in the east.^[4]

There is some confusion as to the certain identification of the species, so it is considered unsafe for eating.^[5] While classified as inedible by some field guides,^[6] it seems to have been traditionally consumed in much of world without noted ill effects.^{[citation needed]} More recently, in Europe it has been identified as responsible for poisonings.^{[citation needed]}

The species is reportedly consumed in China's Yunnan province, where it is generally known as 荞面菌 (Pinyin: qiao mian jun; lit. 'Buckwheat Noodle Mushroom') on account of this property, despite the fact that its proper name is 黄绿口蘑 (lit. 'Yellow Green Mouth Mushroom').^{[citation needed]}
