LIGHT-COLORED RESUPINATE POLY- 

 PORES— I 



William A. Murrill 



In Mycologia for September, 191 9, preliminary notes were 

 published on 35 species of Poria described from North America, 

 and, in the January number, Trametes serpens and Poria medul- 

 lapanis were considered. None of Peck's species have been in- 

 cluded because these were discussed in detail by Overholts in 

 Bulletin 205-206 of the New York State Museum, published in 

 June, 1919. 



It is now my intention to take up various white, gray, yellow, 

 rose-colored, and purple species that occur in temperate and 

 tropical North America and make notes on their history, distin- 

 guishing characteristics, hosts, distribution, etc. The object I 

 have in view is not to publish at this time a comprehensive 

 systematic treatment of the group, but to stimulate collectors 

 throughout the country to observe, collect, and study these diffi- 

 cult resupinate forms in the fresh condition, noting spore meas- 

 urements, colors, and other perishable characters. 



The descriptions included are mainly from dried specimens. 

 Before the hundreds of such specimens in the herbarium here 

 can be intelligently discussed, referred to, or classified, they must 

 be named — and more complete descriptions can be prepared 

 later. 



The numbers following the collectors' names are those found 

 accompanying the specimens. Sometimes they are only determi- 

 nation numbers and mean nothing except to the collector.
