STUDIES OF SOIL FUNGI: III. NEW SPECIES OF CONIOCHAETA, CHAETOMIDIUM, AND THIELAVIA

Abstract

Descriptions and illustrations are given for three new species of Ascomycetes having colored, one-celled ascospores and isolated from forest soil by J. H. Warcup. Coniochaeta tetraspora Cain sp. nov. has dark spiny hairs on the perithecium. The phialospores and blastospores are typical of the genus. The soil from which it was isolated came from Queensland, Australia. Chaetomidium minutum Cain sp. nov. has short, curved hairs on the globose, nonostiolate perithecia. The soil sample came from N. Queensland, Australia. Thielavia variospora Cain sp. nov. has black, nonostiolate, bare perithecia and was isolated from soil collected in New Guinea.
