The season of 1965 was a peculiar one as to the pattern of rainfall throughout the state and the generally low temperature. The result was that in certain areas a relatively large number of unusual fungi were found fruiting, and an equal number of so-called common species did not appear or were found very sparingly. One of the areas which was particularly fruitful was Sugar Island in the St. Mary's River, east of Sault Ste. Marie, and from there westward along the Lake Superior shore to Grand Marais. Heavy rains in July and August kept the pine barrens well soaked, and it was this type of habitat--open pine forests with large patches of Cladonia in open spaces--that produced some of the most unusual fungi. This was especially true of areas ordinarily so hot and dry during midsummer that one would never think of looking for fleshy fungi in them. The largest single group of species in this category belongs to the genus Rhizopogon. Three previously undescribed species and one new record for the state were found in this habitat. Ordinarily, species of Rhizopogon are considered hypogeous, but in the Culhane Lake area, for the most part, they simply occurred on the duff under the dense cover of lichens (mostly species of Cladonia).
