title: A new species of Poroconiochaeta from Russian soils.
abstract: Poroconiochaeta tetraspora sp. nov., isolated from soil of Russia, is described and illustrated. The new taxon differs from P. discoidea in its four-spored asci (eight-spored in P. discoidea) and from P. punctulata in the pattern of ascospore ornamentation, which is conspicuously pitted in P. tetraspora (punctulate in the other species). The new combination Poroconiochaeta savoryi is proposed and discussed.
