 Cyathiis Poeppigii Tul. Ann. Sci. Nat. III. i : 'jj. pL ^. f. 



23-25 ; pl- 5- /• 3-4- 1 844. 



Peridia slender, goblet-shaped, 7-12 mm. high, 5-7 mm. wide 

 at the top, about i mm. at the base of the stem, dark chocolate- 

 brown, the outer surface somewhat shaggy, peeling, leaving a 

 comparatively smooth, deeply and closely striated surface, corre- 

 sponding with the deep inner striations, the inner surface brown, 

 somewhat lighter colored than the outer surface, somewhat shiny, 

 deeply striate ; mouth minutely fimbriate ; sporangioles blackish, 

 flattened, dull, 2-2.5 mni- in diameter; funiculus long; spores 

 38—45 fi long, 18—22 fi in diameter, very thick-walled, granular 

 within, oblong and often slightly curved. {PL i^. f. 1-4..) 



Growing singly and in groups on manure and wet ground. 



St. Croix (Danish West Indies) : A. E. Rickscckcr. 



This species was originally described from Cuba and French 

 Guiana ; it is easily distinguished from the other striated species 

 of CyatJiia by its unusually large spores, and by its deeply and 

 closely striated outer surface. 



2. Cyathia Berkleyana (Tul.) 



Cyatlms uiicrosporus ^ Berkley anus Tul. Ann. Sci. Nat. III. i : 

 74. 1 844. 



Peridia small, cup-shaped, 5—8 mm. high, 5-7 mm. wide at 

 the top, very much narrowed and rounded at the base, brownish 

 outside and somewhat shaggy ; mouth finely fimbriate, the inner 

 surface of the peridium shiny, grayish-brown, lighter colored than 

 the outer, coarsely striate ; sporangioles small, 2 mm. in diameter, 

 shiny, nearly black, flattened; spores small, 6-8 /i long, 4-6 /i 

 wide, somewhat thick-walled, hyaline. (/-*/. ^-Z,/- 5-7.) 



On decayed stems of coarse herbaceous plants. 



Jamaica : Cockerell. 



This species was originally described from Brazil ; it some- 

 what resembles small specimens of Cyathia hirsnta, but it differs 

 from that species in the texture of the outer coat, which is much 

 less shaggy and thick, and in the much smaller spores.
