1918] TEHON—CLITHRIS 555 
hyaline, slightly exceeding the asci and coiled apically to form a 
thin, hyaline epithecium. Asci long, narrow, 110X7 u, 8-spored; 
spores filiform, 1110, fragmenting when mature, and pale 
smoky in color. 
On dead leaves of Clusia rosea. Desecheo Island, no. 1595 (type). 
Although occurring on the same leaf with C. clusiae, C. minor is readily 
distinguished by its smaller size, and by the abundance of hyaline paraphyses 
which only slightly exceed the asci and are coiled apically, forming a thin, 
hyaline epithecium. 
Clithris pandani, sp. nov.—Spots 0. 25~1 cm. in diameter, other- 
wise similar to those of C. clusiae and C. minor. Ascomata small, 
dark, subepidermal, erumpent, 570X110. Paraphyses numer- 
ous, exceeding the asci and united above into a pale yellowish 
epithecium. Asci long, narrow, 917 uw, 8-spored; spores filiform, 
1X91 uw, fragmenting when mature, and pale smoky in color. 
On dead leaves of a cultivated species of Pandanus. San Juan, no. 4090 
(type). 
This species is the smallest of the three; otherwise its superficial char- 
acteristics are much like those of C. clusiae and C. minor. The tips of the 
paraphyses are expanded above (but not coiled) and united into a pale yellowish 
epithecium. 
Types of these species are deposited in the Herbarium of the 
University of Illinois.
