Appearance
The Parrot Toadstool is a small mushroom, with a convex to umbonate cap 1–3 centimetres in diameter, which is green when young and later yellowish or even pinkish tinged.The 2–4 cm stipe is green to greenish yellow. The broad adnate gills are greenish with yellow edges and spore print white. The green colouring persists at the stem apex even in old specimens.
Its odour and taste are not distinctive. There are no known chemical tests. It fruits late summer to autumn.
Naming
It was formerly known as ''Hygrocybe psittacina'', but a molecular phylogenetics study found it to belong in the genus ''Gliophorus''. It had already been placed in ''Gliophorus'', but it had been considered a synonym of ''Hygrocybe''.
Distribution
''Gliophorus psittacinus'' is widely distributed in grasslands in Western Europe, Iceland, Greenland, the Americas, South Africa and Japan, being found in late summer and autumn.In Europe it is apparently in decline due to the degradation of habitats. Early Australian records of this form have been found to be the similar green toadstools ''Gliophorus graminicolor'' or ''G. viridis'' on reexamination. Gliophorus psitacinus is known to occur at one site in the Lane Cove River valley near Sydney.
