UNREPORTED MICHIGAN FUNGI FOR 1915 AND 1916, WITH 



AN INDEX TO THE HOSTS AND SUBSTRATA 



OF HASIDIOMYC'ETES. 



HY ( . H. KAUFFMAN. 



Tlie following plants liave been added to the C'ryptogainie Herbarium 

 of the University from Miehigan. Dr. jNIains and Dr. Povah have com- 

 munioated the rusts and mucors. Through tlie kindness of Prof. Burt 

 a number of accumulated Theleplioraceae have been properly named. 



It has seemed worth while to put on record also the data of many 

 years concerning tlie distribution of the Basidiomycetes on the various 

 hosts and woody substrata. These data are not by any means complete, 

 but it will be seen that they extend very materially the distribution as so 

 far given in our standard host indices. A large part of these data have 

 been gathered bv the senior class in forestrv, who have annually col- 

 lected at Ann Arbor and also on a trip to New Richmond, Mich., during 

 the last six years. Some errors may have crept into the determinations 

 of liost, but in nearly all cases the material was checked by myself.
