Hypomyces luteovirens

[ Ascomycetes > Hypocreales > Hypocreaceae > Hypomyces . . . ]

by Michael Kuo

This species of Hypomyces is a parasite on various species of Russula. It is easily recognized by its yellow-green color. It seems less avid about its parasitism than some species of Hypomyces, and tends to cover only the upper stem and gills of the host mushroom, leaving it fairly recognizable.

Despite the fact that it may parasitize some edible russulas, Hypomyces luteovirens should not be collected for the table.

Description:

Ecology: Parasitic on various species of Russula, which have diverse habitats; widely distributed in North America.

Microscopic Features: Spores 30-36 x 4.5-5.5 µ; without septa. Asci 160-200 x 5-8 µ.
