21 FUNGUS-FLOKA. 



Marked by the three layers forming the peridium (seen 

 in a microscopic section) and the peridiola, with a depression 

 or umbilicus in the centre of one of the flattened sides from 

 vvhich the funiculus springs. 



Cyathus striatus. Hoftm. (fig. 7, p. 28.) 

 Obconic, apex truncate, at first closed by a pale epiphragm ; 

 lead-colour and striate within, outside hirto-tomentose, 

 brownish, peridiola subcircular, comjiressed, about 2 mm, 

 across; spores elliptic-oblong, colourless, smooth, 18-22 x 

 10 fx. 



Cyathus striatus, Berk., Outl. 312, pi. 2, f. 3 ; Cke., Hdbk., 

 11. 1199 ; Mass., Mon. Gast., p. 54, f. 48. 



On wood, twigs, fir-cones, &c. Fasciculate; from i-§ in. 

 liigh. Distinguished by the fluted inside of the peridium. 



Cyathus vernicosus. D.C. (fig. 6, p. 20.) 



Campanulate, becoming broadly open, inside smooth, even, 

 outside silky becoming smooth ; peridiola circular, bicunvex, 

 blackish, 3-4 mm. across; sj)ores elliptical, colourless, 

 12-14 X 10 /A. 



Cyathus vernicosus, Berk., Outl. 312, pi. 21, f. 1 ; Cke., 

 Ildbk., n. 1199; Mass., Mon. Gast., p. 55, f. 49-51. 



On the ground. Clustered ; about -^ inch high. 



Var. agrestis. 



Smaller than type, hemispherical, erect. 



CEUCIBULUM. Tul. (fig. 5, p. 20, and f. 8, p. 28.) 



Wall of peridium double, thick, at first continuous over 

 the apex as a flat eijiphragm ; peridiola numerous, com- 

 pressed, attached to the peridium by a long cord (funiculus) 

 which springs from a iiijiple-like tubercle situated centrally 

 on one of tlie flattened surfaces of the peridiolum. 



Criicihulum, Tul., Mon. Nid., Ann. Sci. Kat., ser. 3, v. i., 

 p. 89 ; Mass., Mon. Gast., p. 56. 



Distinguished from Cyathus, its nearest all}', by the pcridial 

 wall consisting of two layers only, and in the funiculus 

 springing from a projection, and not from a dejiiession <ir 

 umbilicus on the flattened side of the peridiolum.
