Summary. The fungus Dematium pullulans de Bary, is in its perfect stage Anthostomella pullulans (de B.) comb. nov. The mature ascigerous stage occurs in nature, and in immature form has been obtained in pure culture from both the conidium and the ascospore of the organism. A. pullulans retains vitality through all periods of natural drought and cold in this country by chlamydospores and microsclerotia; the perithecial stage is not essential for its continued existence, and appears to be formed intermittently only. Six strains of this one species, A. pullulans , are described, showing the extent to which variation by transitional stages may occur within the species. The fungus is saprophytic, or weakly parasitic, but non‐pathogenic, and is of promiscuous habit as regards host material.
