Humidicutis mavis

Appearance

''Humidicutis mavis'' is a small mushroom with an umbonate cap 4–5 centimetres in diameter, initially conical and later flattening to almost flat. It is smooth and ivory- to pure white in colour with an ivory umbo. The cap is textured with radial fibres, along which it may split, with the gills dividing between the split. The hollow white stipe is 5–6 cm high and 0.3–0.6 cm thick and may be swollen at the base. The white gills are adnexed or free, and thick or distant with even margins. The spore print is white and the hyaline spores are more or less oval, measuring around 6–9 x 4.5–6 μm.
