Includes a key and descriptions of all Russulas then known from Michigan
Keys to genus for Agaricales and common fleshy Ascomycetes, and keys to species for Michigan polypores.
Remaining white-spored Agaricaceae, plus pink and brown-spored genera, with Inocybe and Cortinarius by Kauffman and Pholiota and Hypodendron by Overholts.
I can't find Hypodendron in The Dictionary of the Fungi, but it does say that Singer synonymized Hypodendrum with Pholiota, so these two taxa are probably the same thing, since Earle was Murrill's predecessor at the NY Botanical Gardens.
And of course it might just be a typo in The Dictionary...
Bessey: "very full descriptions of all species of Agaricaceae known to occur in Michigan, and, in many genera, of all species recognized in Northeastern United States. Illustrated by excellent photographs."
This book is available in a 1971 Dover reprint as The Gilled Mushrooms (Agaricaceae) of Michigan and the Great Lakes Region
