The type specimen is at the New York Botanical Garden. 



3. Rhinotrichum fulvum Berk. & Curt. Grevillea 3 : 108. 1874 



Stratum thin, fulvous ; hyphae septate ; fertile branches septate, 

 ultimate divisions elongate, with spicules ; spores subglobose, 

 granular, 15-16 fi. 



Specimens examined: South Carolina, Ravenel (type, spores 

 only). 



The description is compiled largely from the original, as the 

 material at hand was too meager for proper study. It seems very 

 near R. Curtisii. Rhinotrichum Thzuaitesii var. fulvum Grove is 

 reported from England. It has verrucose spores, 7-10 fi. 



4. Rhinotrichum Curtisii Berk. Grevillea 3 : 108. 1875 

 Rhinotrichum Sumstinci Peck, Bull. Torrey Club 34: 103. 1907. 



Stratum effused, thick, golden-yellow, brownish in older speci- 

 mens ; hyphae branched, septate, 8-12^ thick; fertile branches 

 erect, branched, septate, ultimate divisions usually swollen, cov- 

 ered with spicules ; spores globose or subglobose, smooth, variable 

 in size, 12-16 /a. 



On decayed wood. 



Specimens examined: New York, Peck; Pennsylvania, Sum- 

 stinc; Ohio, Kellerman; South Carolina (type). 



In the original description, Aspergillus laneus Schw. is given as 

 a synonym. The specimen in the Academy of Sciences, Philadel- 

 phia, marked Aspergillus laneus is too scanty for proper identifi- 

 cation and therefore the real relationship between these two spe- 

 cies could not be definitely determined. 



Rhinotrichum Sumstinei does not seem to be specifically dif- 

 ferent. The size and the shape of the spores agree with R. 

 Curtisii. The color is given as "tawny-brown." The type at 

 Albany and the cotype in the Carnegie Museum, Pittsburgh, were 

 examined. 



The color of this species as well as of other species depends 

 very much upon the exposure to the sunlight. When exposed 

 to strong sunlight the color becomes darker, even brown. In a 

 shady or secluded place the lighter shades of yellow predominate.
