Durand : New or Noteworthy Geoglossaceae 185 



On soil, Cherrydale, Va., 17 Sept., 1910, W. H. Long no. 2248 

 (D) ; Bermuda, Nov.-Dec, 1912, Britton, Brown and Seaver no. 

 1364 (NY). 



This interesting addition to the geoglossaceous flora of North 

 America was first described by Winter from Brazil. It is one of 

 the few known species with 15-septate spores. It is closely allied 

 to G. pygmaeum Ger., from which it differs in its shorter spores, 

 and especially in its more robust, longer, remotely septate para- 

 physes. I have not seen Winter's type, so that the identification 

 depends upon the description only. Only two plants from each 

 of the above mentioned collections have been seen. 



Microglossum longisporum Durand 



On the ground, Cherrydale, Va., 10 Sept., 1910, W. H. 

 Long (D). ■ 



This agrees in all respects with the previous collections from 

 New York, North Carolina and Michigan. 



Mitrula muscicola E. Henn. 



On wet moss close to the water's edge, Lake Agnes, Alberta, 

 11 Aug., 1915, Durand n. 10413. 



The following notes were made from the fresh material: 



Ascomata 1— 1.5 cm. high, entirely pale cinnamon-brown with 

 a tint of tan ; stem slender, terete, smooth, 0.5-1 mm. thick ; as- 

 cigerous portion abruptly distinct from the stem from which it 

 is slightly free below, hemispherical to oblong-ovate in shape, 

 even, or irregularly furrowed, or, in extreme eases, cerebriform, 

 2-3 mm. wide and high, slightly darker than the stem. 



This species is doubtfully distinct from M. gracilis Karst., pre- 

 viuosly reported from Labrador and Newfoundland, and more 

 recently found in quantity in Colorado by Seaver. I searched for 

 moss-inhabiting Mitrulas carefully but in vain at various points 

 along the Alaskan coast as far north as Skagway. 



Trichoglossum confusum Durand n. sp. 

 T. Rehmianum (P. Henn.) Durand, Ann. Myc. 6: 439. f. 93, 

 168. 1908.
