EIGHTH REPORT. 
UNREPORTED MICHIGAN FUNGI FROM PETOSKEY, DETROIT 
AND ANN ARBOR FOR 1905. 
C. H. KAUFFMAN. 
^ The following list of fungi were collected chiefly around Petoskey, 
Emmet County, by the writer, and around Detroit by the Detroit Myc'o- 
logical Club. As the data show, the forms from northern Michigan 
were obtained mostly in a primeval forest, just back of the Bay View 
resort, and belonging to that Association. This forest covers over one 
hundred acres and has within its limits a low area of hemlock and 
yellow birch, and an ancient cedar swamp; a part of it rises rather 
abruptly some seventy-five feet or more to form an extensive terrace 
covered with hard maple. A great variety of habitats are thus formed 
from a mycological point of view, and the yield of unreported plants 
has been correspondingly large. The ground is covered in places by 
the prostrate, mossy trunks of mighty hemlocks and forest debris, or 
carpeted by the clean mass of magnificent mosses beneath the cedars, 
while the maple area is either covered with a dense undergrowth of 
young saplings or with a tangle of rottting maple trunks. 
The Detroit Mycological Club through its energetic president, Dr. 
O. E. Fischer, have added to our known flora in the list below some 
fifty species. Their collecting was mainly done in the neighborhood of 
Detroit, Wayne County, in its parks, on Grosse Isle, and especially 
in a inch oak woods about seven miles from the city. I take this oppor¬ 
tunity to thank Dr. Fischer and the Club for the large amount of 
material sent me during the past season. 
Thanks are also due Prof. G. F. Atkinson and Dr. C. H. Peck for their 
valuable assistance in diagnosing the Basidiomycetes sent them, and to 
Dr. E. J. Durand for similar services among the Ascomycetes. 
In addition to the two groups mentioned, a list of the Phycomycetes 
of Michigan will be included. Most of this list comes from the Univer¬ 
sity herbarium or was collected or found in cultures in the laboratory. 
As m the preceding paper,* the arrangement of groups and families 
will be that of Engler and Prantl Pflanzen-familien; in a few cases, 
however, well-known generic names are retained for the sake of con¬ 
venience. 
It is to be hoped that the work will be continued from year to year 
and that more clubs throughout the State will take an active part
