2. Mitrula musicola Henning. Oefvers. af 

 K. Vet.-Akad. Forh. 1885. 



Laggan, Alberta, Canada, Aug., 1903. 

 Hone 257. 



Growing upon Webera nutans Schreb. in 

 moist spruce and balsam woods at about 7,000 

 feet elevation. 



Caespitose, erect; pileus yellowish to tan- 

 colored, obtuse, slightly Morchella-like, with 

 a tendency to be ribbed or rugose, glabrous, 

 about 4 mm. long; stipe lighter colored to 

 whitish, glabrous, solid, about 10 mm. long; 

 spores elliptical, bent, non-septate, colorless, 

 in two rows in ascus, up to 10-12 x 2-3 mic; 

 paraphyses filiform, up to 2 mm. broad. 



This seems to be M. musicola Henning 

 rather than M. rehmii Bresad. on account of its 

 smaller size and only slightly rugose pileus. Dr. 

 Rehm considers that it is either M. musicola 

 Henning or M. gracilis Karst., but he prefers 

 the former.
