The Boleti of the Frost herbarium 



William A. Murrill 

 (with plates 36-40) 



A brief account of the life and botanical work of C. C. Frost was 

 published in the August number of Torreya, and the reader is re- 

 erred to that account as a general introduction to the present more 

 critical paper, which was made possible by the recent generous 

 loan of the Frost collection of Boleti by the University of Vermont 

 This collection is very rich in type material, containing prac- 

 lc ally all of Frost's published species and a number of species 

 stl 'l in manuscript, which I have treated separately. A number of 

 s eets of type specimens, or type duplicates, twenty or more, were 

 Sent to C. H. Peck at Albany, where they are still well preserved, 

 eck never saw Frost, nor the remainder of his herbarium. He 

 gan w °rk near the close of Frost's active life, but his advantages 

 a PPear to have been greater, and we find Frost turning to him 

 ln l8 74 for certain determinations and for assistance with the 



Amh 



erst Catalogue. 



There are a number of references in Frost's notes and descrip- 

 °ns to the opinions of Peck regarding various species. There 

 are also four type specimens, or co-types, in the collection, which 



Were sent him 



Peck, B. 



elbensis Peck, and B. palusU 



iplip 



0r tunately, in very poor condition. 



h 



r °st kept a separate list of spore measurements of the Boleti ; 

 f e vv 'as not particular about spore coloration. I have made a care- 

 u examination of his types microscopically and find his figures 

 Usu % correct.
