Description

The cap is greenish-brownish yellow, slightly moist, and has dark fibrils near the center. The gills and stipe are whitish-yellow. The odor is mild to mealy and the taste mild to unpleasant.[4]

Edibility

There is some confusion as to the certain identification of the species, so it is considered unsafe for eating.[4] While classified as inedible by some field guides,[5] it seems to have been traditionally consumed in much of world without noted ill effects. More recently, in Europe it has been identified as responsible for poisonings.

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').

Similar species

Tricholoma flavovirens is usually larger and fleshier, with more solid yellow gills and stipe and a less fibrillose cap.[4] Other similar species include Tricholoma arvernense, and T. viridilutescens.[4]
