Abstract

Acrospermum includes a few small and inconspicuous species of club-like fungi in which the single erect ovate or flattened spore chamber is borne on a stalk or a constricted base. Lindau (in Engler & Prantl, Nat. Pfl. I. 1:278. 1896) erected for the genus the monotypic family Acrospermaceae, based largely on the flattened ascocarp and slit-like dehiscence of A. compressum Tode ex Fries, the oldest and best-known species, and included the family, with some reservation, in the Hysteriales. Other authors have assigned it to the Hypocreales and Sphaeriales. Brandriff (Mycologia 28:228-235. 1936) gives a review of the pertinent literature. She succeeded in growing A. compressiim in pure culture and made a histological study of the development of the ascocarp, as a result of which she decided that the ascigerous cavity is a true locule, hence the entire ascocarp consists of an erect, uniloculate stroma and that the species should be assigned to a position among the loculate groups "in the vicinity of the Coryneales and Pseudosphaeriales." In accordance with this suggestion, verified by my own observations, I included the Acrospermaceae in the Dothideales in the 1950 edition of the Outline of the Fungi.
