A large and heterogenous group of fungi whose common characteristic is the absence of a sexual state. Many of the pathogenic fungi in humans belong to this group.

Diseases of plants.

A plant genus of the family LAMIACEAE. The common names of beebalm or lemonbalm are also used for MELISSA. The common name of bergamot is also used for Citrus bergamia (CITRUS).
