03E5BC4D296BFFE3FF0FF83AFF65FE4C.taxon	diagnosis	Diagnosis: — Hygrocybe rimosa is characterized by its yellow to reddish pileus with a paler margin, striated pileus with radial fibrils, broad to ventricose lamellae, subglobose to oblong basidiospores measuring (7) 7.5 – 11 × 5 – 8 (8.5) μm. Hygrocybe rimosa differs from H. intermedia in having a smaller pileus, white lamellae, a slenderer stipe, broader basidiospores, and the distribution in southern China.	en	Wang, Chao-Qun, Zhang, Ming, Li, Hai-Jiao, Huang, Hao, Deng, Wang-Qiu, Li, Ting, Luo, De- Jun, Li, Tai-Hui (2021): Hygrocybe rimosa (Hygrophoraceae, Agaricales), a new poisonous species from southern China.

Context thin, white, unchanging when injured, brittle. Lamellae free, ventricose, up to 0.6 cm broad, subdistant, white, margins concolorous with faces, waxy, thick, fragile, with 1 – 3 unequal lamellulae between two entire lamellae, eroded at edge. Stipe 2 – 7 cm long, 0.2 – 0.6 cm thick, central to slightly eccentric, cylindrical, usually slightly enlarged downwards, white, pale yellow to yellow (3 A 3 – 6) when mature, usually white or paler at apex, with inconspicuous longitudinal stripes, waxy, hollow. Taste mild. Odor indistinctive.
