Teleomorph: Nectria (Fries) Fr.
Colonies are fast growing, hyaline or bright-coloured, suede-like or woolly. Sporodochia may occasionally be present. Conidiophores consist of simple or repeatedly verticillate phialides, arranged in brush-like structures. Phialides are cylindrical to subulate, with small collarettes producing hyaline, smooth-walled conidia, which are arranged in slimy masses. Two types of conidia may be produced; macroconidia which are one to several septate, hyaline, straight or curved, cylindrical to fusiform, with a rounded apex and flat base; and microconidia which are one-celled, which are usually clearly distinct from the macroconidia. Chlamydospores may be present or absent, hyaline to brown, spherical, formed singly, in chains or in clumps, intercalary or terminal. RG-2 organism if isolated from humans.
Culture, chlamydospores and macroconidia of Cylindrocarpon lichenicola.
The genus contains 35 species, is widespread, isolated mostly from soil and is recorded as an occasional human and animal pathogen. Cylindrocarpon differs from Fusarium by lacking an asymmetrical foot-cell on the macroconidia.
