Nigrospora

 

The white woolly colonies grow fairly rapidly. Spores (conidia) are produced singly on swollen urn-shaped conidiophores and are egg-shaped to flattened-spherical, black, and often have an equatorial colourless line or germ slit. Occurring as parasites on living grasses but also present on dead ones; easily isolated from dead lawn grass in the autumn. Holomorph: Khushkia. Ref: Ellis 1971
