Traditionally, "Clitocybe" was a genus of gilled mushrooms that lacked partial veils and featured white, yellowish, or pinkish spore prints, as well as gills that were broadly attached to the stem or run down it. Some mycologists separated "Lepista," featuring clitocyboid mushrooms with spiny spores and pinkish spore prints, as a separate genus, while others viewed the lepistas as a section within the genus Clitocybe.
If you noticed the quotation marks I placed around "Clitocybe" and you are now waiting for me to pull the taxonomic rug out from under your feet, I congratulate you on having a much better sense of punctuation than my freshmen, who appear to believe we should use "quote marks" for "anything" we "want" . . . and yes, the writing is on the wall: while a comprehensive DNA study of the mushrooms traditionally placed in Clitocybe has not yet been done (to my knowledge), enough work has been done to determine that the mushrooms in question are not all closely related. Some, in fact, are only distantly related, and much of the genus will have to be split up among several existing (and several new) genera.
Identification of clitocyboid mushrooms, beyond a handful of easily recognized "field guide species," often depends on microscopic analysis—and Clitocybe literature for North America is hard to find and hard to work with. H. E. Bigelow's two-part monograph (1982, 1985) of the North American Species of Clitocybe is selling online for about $150 these days. If you are in California, Denise Gregory's San Francisco State University masters thesis on Clitocybe in California is essential. Further Clitocybe literature is listed below.
As far as pronouncing Clitocybe, make it rhyme with "I toss a bee." While my usual response to the question of how to "correctly" pronounce scientific names is, "Who cares?" (see this page for details), the case of Clitocybe may be an exception if you want to avoid the strange looks you will get from mushroom folks when you pronounce it as though it were an English word. It is one thing to be received as a bumpkin who doesn't know how to pronounce scientific names, but it is another thing entirely to be received as a perverted bumpkin who doesn't know how to pronounce scientific names. Also note that the late Gary Lincoff, when forced by his editors for the Audubon Society Field Guide to North American Mushrooms (1992) to create "common" names for our continent's mushrooms, used "trich" for species of Tricholoma ("soapy trich" for Tricholoma saponaceum, and so on) but did not employ a similar strategy for species of Clitocybe.
