FUNGI. 1 1 



LOPHIUM LEPTOTHECUM, n. sp. Scattered or gregarious : 

 ascocarps erect, elongate, compressed, the base sunken in 

 the wood fibers, black, brittle, carbonaceous, roughened by 

 transverse striations, black and shining within, lips thin, 

 closely compressed, l-ljmm. high, about Jmm. broad with 

 the sides nearly parallel or slightly tapering upward, about 

 Jmm thick ; asci numerous, very long, 400-500x6^; para- 

 physes abundant, threadlike, very slender, less than I//, 

 thick, not conspicuously branched ; ascospores dark-brown 

 equalling the ascus, about 2/u. thick, conspicuously and 

 closely septate, the cells 2-3/x, long, when freed from the 

 ascus usually breaking into pieces, 12-16 feet long. 



On barkless dead twigs of Amelanchier (n. 83), and Quer- 

 cus and Rlius (n. 84) at Hermosa, Colo., March. Ellis records 

 doubtfully three species of this genus as occurring in North 

 America. The first seems to have been a case of mistaken 

 identification ; and of the twoSchweinitzian species he is un- 

 able to give any account of the asci and spores. This new 

 one seems therefore to be the first fully authentic member 

 of this genus to be found in America.
