FUNGI. 27 



11,000 feet, June 29, n. 230. This is a new genus to North 

 America. Only three species have heretofore been de- 

 scribed, one from Terra del Fuego and two from France. 



DOTHIDEACE^E. 



ROPOGRAPHUS HYSTERIIFORMIS (Karst) Sacc. Syll. ii. 648. 

 On decorticated branches of Picea Engelmannii, Bob Creek, 

 10,500 feet, June 28, n. 202. This peculiar fungus has 

 heretofore been found only in Northern Europe on decorti- 

 cated wood of juniper and pine. Our specimens agree 

 closely with published descriptions. We have not seen 

 European specimens. 



SORDARIACE.E. 



HYPOCOPRA FIMICOLA (Rob.) Sacc. 1. c. i : 240. On cow 

 dung, Bob Creek, 10,500 feet, July 2, n. 1105. 



SPH^ERIACE^E. 



HERPOTRICHIA NIGRA Hartig Hedw. xxvii. 13. On living 

 leaves of Picea Engelmannii, Bear Creek Divide, 11,000 feet, 

 June 29, n. 232. 



This has not before been reported from America. The 

 asci soon vanish, and at full maturity the ascospores are 

 fuliginous. In our specimens the perithecia often reach 

 5mm. In other respects it closely agrees with the descrip- 

 tion given by Hartig. It was also observed on Mt. Hes- 

 perus near timber line, but was not seen below H',000 feet. 

 This was previously collected by C. F. Baker on spruce in 

 northern Colorado, July 13, 1896, at Cameron Pass, 10,000 

 feet, and distributed by him under the name of Lasiosphdsria 

 Coulteri, Peck. It closely resembles that pine-inhabiting 

 species externally, but the spores are entirely different.
