title: Three new species of Chaetomium from soil.
abstract: Chaetomium macrostiolatum sp. nov., Chaetomium olivicolor sp. nov. and Chaetomium tarraconensis sp. nov. isolated from Nigerian, Indian, and Spanish soils respectively, are described and illustrated. The first species is characterized by ascomata with a very broad ostiole and yellow hairs, and limoniform ascospores; the second by its thermotolerant growth, inconspicuous and short straight ascomatal hairs and fusiform ascospores; and the last by its unusual, irregularly-shaped ascospores and subglobose ascomata with flexuous to undulate, unbranched ascomatal hairs.
