HEBELOMA
The Species are not very well known and are difficult to identify. Many of
them have a bitter or unpleasant taste and the genus is not one to attract
amateur collectors. They are not recommended for eating although there is no
evidence that they are poisonous. Only the one species, F. spumosa (Fr.)
Kummer, which is one of the commonest of the genus, is described here.

when moist, pale sulphur-yellow except on the disk which is fulvous-tinged,
margin even, flesh thin, tinged yellowish, lamellae adnate to shghtly sinuate

In groups on decaying wood or on the ground in woods, fairly common.
July-Oct.
This is one of the commonest species of the genus and is principally
characterized by the sulphur-yellow to greenish yellow margin of the pileus
and the fulvous to tawny disk.
HEBELOMA
Hebeloma includes a group of rather poorly known brown-spored species.
They have viscid pilei, adnexed or emarginate lamellae, and a volva and annu-
lus are lacking but some species have a fibrillose veil. The spores are dull
colored in mass, alutaceous or dull brown, never bright rust-colored as in
Inocybe or Cortinarius, and the colors of the pileus are usually somewhat dull
also.
The species are not well known and are difficult to identify. Some of the
species are known to be poisonous and none are recommended as food. It is a
genus to be avoided by the amateur. Only one species is described here.
