Identification
Separation from other mycetophilid tribes requires examination of male genitalia, particularly the gonostylus structure. Wing venation patterns, including details of the fork of M and the presence or absence of certain crossveins, provide additional diagnostic characters. External alone is generally insufficient for definitive tribal assignment.

Habitat
Associated with moist, shaded environments including forest understories, riparian zones, and caves. Larval development occurs in decaying wood, fungal fruiting bodies, and other substrates supporting fungal growth. frequent the same microhabitats as their developmental sites.
Distribution
Worldwide distribution with representation in all major biogeographic regions. Records span the Nearctic, Palearctic, Neotropical, Afrotropical, Oriental, and Australasian regions. Specific range limits vary by and .
Seasonality
activity generally peaks during periods of high humidity and fungal fruiting, often spring through autumn in temperate regions. Some exhibit extended or year-round activity in tropical and subtropical zones.
