A New Emericellopsis from Wisconsin, With Notes on Other Species

Abstract

encountered several times in soil samples taken from wet prairies in Iowa County, Walworth County, and Marquette County. In all, one hundred nine isolates were obtained. This organism, initially catalogued as WSF 47, was eventually determined to be an undescribed fungus belonging to the genus Emericellopsis van Beyma. Although Emericellopsis was poorly known in mycological circles at the time that the above-mentioned isolations were made, it has since attained considerable prominence. The genus was erected by van Beyma (20) in 1940 for certain fungi that had been isolated from soil in Holland. In van Beyma's article the type species, E. terricola, was fully described; in addition, a variety glabra was very briefly characterized. Apparently the genus was not reencountered in nature until about a decade later, when Malan (13) obtained an isolate from vineyard soil in Italy. This latter investigator, presumably unaware of van Beyma's publication, erected the new genus Peyronellula for his fungus and named the species P. mirabilis. Stolk (19) in 1955 transferred Malan's organism to Emericellopsis and added a third species, E. minima, isolated from African soil. The article by Stolk helped greatly to acquaint mycologists with this interesting but hitherto obscure genus. A fourth species, found in Canada, was described by Cain (3) in 1956 as Saturnomyces huiicola, the type of still another new genus in the Eurotiaceae. The transfer to Emericellopsis was in this case accomplished by Gilman (9). In 1957 a fifth species, E. salmosynne,mta, was described by Grosklags and Swift (11), who had encountered it as the perfect stage of the well-known antiThis study was initiated with the aid of a grant from Lederle Laboratories
