SOME MYCOLOGICAL NOTES FOR 1919* 



L. O. OVERHOLTS 



(With Plates 9 and 10) 



The fungous flora of the mountains of central Pennsylvania is 

 perhaps as rich and as varied as in any other region of the 

 United States. The summer of 1919 was marked by an unusual 

 abundance of rainfall that brought forth such a crop of fungi as 

 had not been produced since 1915- Intensive and extensive col- 

 lecting over several years has added scores of hitherto unre- 

 ported species to the fungous flora of the state. A considerable 

 number of these are of rare occurrence or for other reasons are 

 only imperfectly known. It is hoped that the present paper with 

 the accompanying photographs will help to give these few species 

 a more prominent place in the mycological literature of the 

 country. 



1. Clavaria ornatipes Peck 



The writer has collected Clavarias in considerable abundance 

 for several seasons past, but this is the first collection of this 

 interesting species. The name of Peck's species C. bicolor (later 

 changed to C. vestitipes) for a different plant, would fit this plant 

 nicely, for the color contrast between the drab-gray branches and 

 the wood-brown (Ridgway's colors) stem is quite marked. Per- 

 soon's name, C. trichopus, for a similar if not identical plant, 

 refers to the abundant ascending gray-brown stiff hairs that 

 clothe the stem. C. vestitipes Peck is a much smaller plant. C. 

 krombholzii Fr. (ex Lloyd) is similar in stature and branching 

 but uniformly white in color. The spores of my specimens are 

 globose, smooth, hyaline under the microscope, and measure 

 8-10 fi in diameter. The content is quite granular.
