Ascospore germination, mycelial growth, and microconidial anamorphs of Encoelia pruinosa in culture

Abstract
Germination of ascospores, morphology and growth rate of colonies, and production of microconidial anamorphs of Encoelia pruinosa (Ell. & Everh.) Torkelson & Eckblad were investigated. Rate of germination was high (95–99% within 24 h) on 2% water agar and 2% malt extract agar. Growth rate ranged from medium (3.5–6.4 mm/day) to moderately rapid (>6.4 mm/day) on four media; the colonial morphology of different isolates varied with the media tested. Spherical micro-conidia were produced three ways: by ascospores functioning as phialides, by an Acreinoitium-like anamorph, and by a Myrioconium-like anamorph. The taxonomic implications of these anamorphic associations are discussed.
