The specimens are in the Ellis collection in the New York 

 Botanical Garden and are labeled Rhinotrichum tenerum E. & E. 

 n. sp. I was unable to find any published description of this 

 species and have presumed that the name has not been published. 

 The following descriptive note is found on the label : " Hyphae 

 hyaline, septate, branched, evanescent, 5-6 ^ thick, the terminal seg- 

 ments spiculiferous and bearing the globose, subelliptical, yellow- 

 ish, hyaline, 8-10 /x, smooth conidia with granular contents."
