Mycena interrupta, commonly known as the Pixies' Parasol, is a species of mushroom.

Description

The caps of Mycena Interrupta range from 0.6 to 2 cm, and are a brilliant cyan blue colour. They are globose when emergent and then become a broad convex as they mature, with the centre of the cap slightly depressed. The caps are often sticky and appear slimy looking, particularly in moist weather.

The length of the stipe typically ranges from 1-2 cm long and 0.1-0.2 cm thick. It is white, smooth and the base of the stipe is attached to the wood substrate by a flat white disk, similar to Mycena Austrororida, which, unlike Mycena Interrupta is attached to the wood substrate by a mass of clumped fine hairs.

The gills are white, adnexed, with blue margins. The spores are white, smooth, ellipsoid and have dimensions of 7-10x4-6 µm.[6]

Unlike some other Mycena species, M. interrupta is not bioluminescent.[5]

Habitat and Distribution

The Pixie's Parasol appears in small colonies on rotting, moist wood in rainforests and beech or eucalypt forests. It has a Gondwanan distribution.
