"Inocybe" is a large, complex genus of mushrooms. Members of "Inocybe" are mycorrhizal, and some evidence shows that the high degree of speciation in the genus is due to adaptation to different trees and perhaps even local environments.

Typical mushrooms of the genus are any of various shades of brown, although some lilac or purplish species exist. Caps are small and conical, though flattening somewhat in age, generally with a pronounced raised central knob. The cap often appears fibrous or frayed, giving the genus its common name of "fiber caps". Many species have a distinctive odor, various described as musty or spermatic.

"Inocybe" species are not considered suitable for consumption, although in some under developed countries certain species "Inocybe" mushrooms are eaten.Fact|date=September 2008 Many species contain large doses of muscarine, and no easy method of distinguishing them from potentially edible species exists. In fact, "Inocybe" is the most commonly-encountered mushroom genus for which microscopic characteristics are the only means of certain identification to the species level. While the vast majority of "Inocybes" are toxic, seven rare species of Inocybe are hallucinogenic, [http://www.museocivico.rovereto.tn.it/UploadDocs/104_art09-Guzman%20&%20C.pdf] having been found to contain psilocybin including "Inocybe aeruginascens" which also contains aeruginascine. (N, N, N-trimethyl-4-phosphoryloxytryptamine)

There are hundreds of species of "Inocybe" and a complete listing here is infeasible. Representatives of the genus include:

*"Inocybe adaequata"
*"Inocybe aeruginascens" (psychoactive)
*"Inocybe calamistrata" (psychoactive)
*"Inocybe coelestium" (psychoactive)
*"Inocybe corydalina var. corydalina" Quél. (psychoactive)
*"Inocybe corydalina var. erinaceomorpha" (psychoactive)
*"Inocybe erubescens" (= "I. patouillardii") red-staining inocybe
*"Inocybe geophylla"
*"Inocybe haemacta" (psychoactive)
*"Inocybe hystrix"
*"Inocybe lacera"
*"Inocybe obscura"
*"Inocybe rimosa" (= "I. fastigiata")
*"Inocybe sororia"
*"Inocybe tricolor" (psychoactive)
*"Inocybe violaceocaulis" [cite journal | author = Matheny PB, Bougher NL| year = 2004 | title = A new violet species of "Inocybe" (Agaricales) from Urban and Rural Landscapes in Western Australia| journal = Australasian Mycologist | volume = 24 | issue = 1 | pages = ] . (prev. "I. geophylla" var. "lilacina") In Western Australia, what represents "I. violaceocaulis" was earlier referred to as "I. geophylla var. lilacina" by some Australian taxonomists, which Matheny & Bougher (2005) point to as a misapplication of the name "I. geophylla var. lilacina."
