Durand : New or Noteworthy Geoglossaceae 187 



Trichoglossum hirsutum f. Braziliense P. Henn. 



In the original description of T. hirsutum f. variabile (Mono- 

 graph, p. 438) its possible identity with the forma Braziliense P. 

 Henn., of which no specimens had been seen, was suggested. 

 Subsequent examination of a portion of the type of the latter 

 from Goyaz, Brazil (Ule n. 2027), preserved at Berlin, shows the 

 spores to be regularly 15-septate, 138-160 /x, long, tapering each 

 way from above the middle, instead of 12-14-septate as stated in 

 the original description. It is, therefore, typical T. hirsutum, 

 quite different from forma variabile. 



Trichoglossum Wrightii Durand 



Trichoglossum hirsutum forma Wrightii Durand, Ann. Myc. 6 : 

 438. /• 83, 174. 1908. 



Ascomata clavate, black, velvety, with the numerous, black 

 cysditia, variable in size ; ascigerous portion irregular, occupying 

 about Ys the total length. Asci clavate-cylindric, 250-265 X 20- 

 25 fx. Cystidia black, acute, projecting only slightly beyond the 

 hymenium. Spores 8, fasciculate, 105-145 X 7 brown, clavate, 

 broadest above the middle, mostly 8-9-septate, rarely 5-, 6-, or 

 7-septate, stout. Paraphyses cylindric, septate, pale brown above, 

 only slightly thickened and strongly curved. 



Cuba: Wright (H). 



Bermuda: Brown, Britton and Seaver, no. 1404 (D). 



In the Monograph this species was described as a form of T. 

 hirsutum, from two Cuban specimens in the herbarium of Har- 

 vard University. A third collection, from Bermuda, has con- 

 vinced me of the correctness of the opinion previously expressed, 

 that it would prove to be a distinct species. The spores resemble 

 those of T. velutipes, but there are eight in each ascus.
