the upper surface, slightly less so on the lower; locules globose, 

 2-4 in each stroma, 150-250 ^ across; asci cylindrical, 87-109 x 

 8-10.5 /*> 8-spored; spores uniseriate, ellipsoidal, hyaline to yel- 

 lowish green, continuous, 11. 5-13 x 3-4 //,; paraphyses very abun- 

 dant (fig. 24). 



This species possesses some of the characters of Phyllachora 

 biareolata Speg., but, through the courtesy of Doctor C. Spegaz- 

 zini, it has been possible to examine a portion of the type material 

 of that species, and our form has been found to be very different 

 in stromatal characters. 



Material examined:

SPHAERIALES 



SORDARIACEAE 



Only one species belonging to this group of dung-inhabiting 

 forms has been reported from the island. The group is probably 

 well represented, but has apparently been neglected by all col- 

 lectors. The writer has been fortunate in seeing two collections 

 in excellent condition. Both of them have been identified with the 

 aid of Griffiths's monograph (17). 



Sordaria humana (Fuckel) Awd., Abhand. naturf. Gess. Halle 

 13:85. 1873. 



Spores obovate, 15-19 x 21-23 p. According to Griffiths, the 

 shape of the spores is the only character which serves to distin- 

 guish this species from S. fimicola, the spores of the latter being 

 ellipsoidal. 



Material examined: 



On human dung. Cornell University Explorations of Porto 

 Rico (Whetzel & Olive), Maricao, Mar. 16, 1896, deposited in 

 Chardon herbarium as No. 1351. 



Pleurage arachnoidea (Niessl.) D. Griff., Mem. Torr. Bot.

 Spores 7-9 x 1 7-19.5 /x, with a very long primary appendage 

 which curves and overlaps the spore below.
