Taxonomy
It was described in 1989 by the German mycologist Rolf Singer who classified it as Cystolepiota potassiovirens.[3]
Description
Cystolepiota potassiovirens is a very small brownish mushroom with brown flesh.[3]
Cap: 1cm wide and convex with a small umbo. The surface is brown to dark brown with a pale orange umbo covered with furfuraceous (bran like) scales. Gills: Free, dark brown and close to crowded. They have a slight ventricose bulge in the middle. Stem: 1.7cm tall and 0.8-1mm thick and subequal. The surface is dark brown with a pruinose (powdery) coating. Spores: Ellipsoidal without a germ pore, hyaline, non-amyloid but greenish in KOH. 3.3-4 x 2.5-3μm. Basidia: 15-21 x 5 μm. Four spored. Smell: Indistinct.[3]
Etymology
The specific epithet potassiovirens derives from the Latin potassio meaning potassium and virens meaning green.[4] This is in reference to the green colouration the spores develop in Potassium Hydroxide (KOH).
