24 FUNGUS-FLOEA. 



Marked by the three layers forming the peridium (seen 

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

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

 which the funiculus springs. 



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

 Ohconic, apex truncate, at first closed hy a pale epiphragm ; 



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



brownish, peridiola subciroular, compressed, about 2 mm. 



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



10 |u. 



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



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

 On wood, twigs, fir-cones, &c. Fasciculate; from ^- J in. 



high. 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, biconvex, 

 blackish, 3-4 mm. across; spores elliptical, colourless, 

 12-14 X 10 fi. 



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

 Hdbk., n. 1199 ; Mass., Mon. Gast., p. 56, f. 49-51, 



On the ground. Clustered ; about i}^ inch high. 



Var. agrestis. 



Smaller than type, hemisphefioal, 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 epiphragm ; peridiola numerous, com- 

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

 which springs from a nipple-like tubercle situated centrally 

 on one of the flattened surfaces of the peridiolum. 



Crucihulum, Tul., Mon. Nid., Ann. Soi. Nat., ser. 3, v. i., 

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



Distinguished from Cyathus, its nearest ally, by the peridial 

 wall consisting of two layers only, and in the funiculus 

 springing from a projection, and not from a depression or 

 umbilicus on the flattened side of the peridiolum.
