(1963) Hygrocybe virescens, commonly known as the lime-green waxy cap,[1] is a species of agaric mushroom in the family Hygrophoraceae.

The cap surface is smooth, moist but not sticky, in age the margin becomes rimose (covered with a network of cracks and small crevices) and often splits into lobes.

[2] Mycologists Steve Trudell and Joe Ammirati suggest that Hygrophorus virescens is very similar in appearance to the European Hygrocybe citrinovirens, and may in fact be the same species.

[4] Hygrocybe virescens appears to be limited in distribution to California, Washington (based on a single collection in Seattle), and Veracruz State, Mexico.

[5] In California[1] and Washington,[4] it is found fruiting in association with redwood trees;[1] the collections in Mexico were among grass and in gardens, near cypress hedges (genus Cupressus).
