The genus Clitocybe is a large assemblage of closely related agaric species differing in relatively few features, such as the presence or absence of clamp connections, the presence or absence of encrusting pigments on the pileus cuticular hyphae, and the color of the spore deposit, which may be white, pinkish, or yellow. Mature basidiocarps typically have pilei which are depressed in xxcenter and decurrent lamellae. The genus, like Russula, is relatively easy for the field naturalist to recognize, but comparatively few of its species can be accurately identified in the field. Many interesting aspects of classification among agarics are brought into focus by a critical study of this genus, such as the fact that Clitocybe, like Russula, should not be regarded as a "white spored genus." Once a critical study has been made, some the the species not known previously can be readily recognized in the field. Those presented here are in this category, and though the basidiocarps of none are known to be edible and desirable, they will be encountered by the collector on occasion and are apt to arouse his curiosity. These species are conspicuous elements in our mushroom flora at the peak of their fruiting cycle. Notes on them have been in our files for some time.
