 376 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



One might regard this fungus as the type species of a new 

 genus distinct from Cyphella or Solenia by the common central 

 mass on which the individual cups are borne, but in Cyphella 

 fasciculata the cups sometimes occur singly and sometimes 

 branching from a common central or basal mass. For this reason 

 it seems best to include the present species in Cyphella through 

 its relationship in plan of structure to C. fasciculata, from which 

 it is specifically distinct in other respects, however. Both these 

 species are excluded from Solenia by their short and globose 

 fructifications and by the absence of a subiculum on the general 

 area over which the clustered fructifications are distributed. 



Specimens examined: 

 New Hampshire: Lower Bartlett, R. Thaxter, comm. by W. G. 

 Farlow, 4, type (in Mo. Bot. Gard. Herb., 43806, and in 

 Farlow Herb.). 

 New York: Adirondack Mts., C. H. Peck, comm. by H. D. House 

 (in Coll. N. Y. State and in Mo. Bot. Gard. Herb., 43818); 

 North Elba, C. H. Peck, comm. by H. D. House (in Mo. 

 Bot. Gard. Herb., 43819). 



21. C. fumosa Cooke, Grevillea 20 : 9. 1891. Plate 19. fig. 11. 



Type: in Kew Herb. 



Fructifications gregarious, membranaceous, cup-shaped, 

 flexuous, sepia or olive-brown and blackening, even, attenuated 

 below into a very short stipe, or sessile; hymenium even; basidia 

 cylindric-clavate, 20 x 4-5 m; spores colorless, even, somewhat 

 flattened on one side, 6-8 x 3|-4 tx. 



Fructifications 1-2 mm. broad. 



On rotting leaves of Gladiolus. South Carolina. 



Cooke described the spores of this species as globose, 4 m in 

 diameter, but I found no such spores in my preparation from 

 the type. Spores 6-8 x 3^-4 m are abundant and are probably 

 the spores of this species, although I could not find any spores 

 still attached to the basidia. I conclude from my microscopical 

 preparations that the fructifications are glabrous. 



Specimens examined: 

 South Carolina: Aiken, Ravenel, 3071, type (in Kew Herb.).
