“Оп living leaves of Sabal Palmetto, Louisiana, Nov. 1885. 
Rev. A. B. Langlois, No. 57. Shallow cup-shaped, thin, substi- 
pitate, oblique, less than 1 mm. across, whitish and nearly 
smooth outside, hymenium bluish or lead colored. Spores 
filiform multinucleate, upper end thickened, curved into a 
semicircle, 40-60 u long by 13 и thick, on short (11-12 x 11-2 и) 
subcylindrical sporophores, which are a little thickened below.” 
This species was distributed in 1891 in Ell. & Ev., N. Am. 
Fungi, 2602, the specimens having been collected on living 
stems of Smilax in Louisiana by Mr. Langlois. Mr. Langlois 
communicated to me still better specimens on dead canes of 
Arundinaria. Тһе fructifications occur scattered here and there 
in grayish areas 2-4 mm. long by 1-1 mm. broad on the surface 
of the stems. Dr. Farlow informs me in a letter as the proofs 
are at hand that the above species is the lichen Heterothecium 
Augustini Tuckm.
