A study of aquatic hyphomycetes of Southeastern Wisconsin

Abstract

This paper presents a portion of the results of a distributional and ecological study of aquatic Hyphomycetes in seven counties of southeastern Wisconsin. Results of the water chemistry studies and laboratory studies on the physiology of these fungi will be published separately in Mycopathologia et Mycologia Applicata. Part of this research was supported by a grant from the Graduate Faculty Research Committee. In the present investigation 28 species, representing 21 genera, were found growing on submerged decaying leaves in streams, lakes and bogs. Three previously undescribed species were found as loose spores in foam samples from Cedar Creek and Sauk Creek. In addition to the species previously reported from Wisconsin by Woelkerling and Baxter, the following species were collected and are listed as new records for the state. Those marked with an asterisk were collected at the UWM Field Station.
