Colonies are spreading, greyish-brown, powdery or suede-like and produce large, globose, membranous to leathery, darkly pigmented, ostiolate pycnidia. Conidia are produced in abundance within the pycnidia on narrow thread-like phialides, which are hardly differentiated from the inner pycnidial wall cells. Conidia are globose to cylindrical, one-celled, hyaline, and are usually extruded in slimy masses from the apical ostiole. RG-1 organism.

Key Features: coelomycete, ostiolate pycnidia producing masses of slimy, hyaline, single-celled conidia.
Members of the genus Phoma have a world-wide distribution and are ubiquitous in nature, with over 2000 species having been described from soil, as saprophytes on various plants, and as pathogens to plants and humans.
