Chondrioderma deplanatum, Host., Mon. Append., p. 17 ; Sacc.,

On rotten wood, leaves, &c. Britain (King's Cliffe, Black- 

 heath, Carlisle) ; France ; Switzerland. 



Sporangia 1 3 mm. when circular, from 3 5 mm. when 

 elongated ; in the elongated form the sporangium is frequently 

 folded on itself, and sometimes it takes two or three spiral 

 turns, leaving a minute cavity in the centre. Distinguished 

 from Chondrioderma difforme by the warted spores and large 

 size of the sporangia, and from C. niveum by the absence of 

 the columella. Sometimes the whole of the outer calcareous 

 coat breaks away in a circumscissile manner close to the adnate 

 base. 



Chondrioderma cmstaceum, Berl. 



Effused or circumambient, crowded, sessile, subglobose, smooth, 

 white, outer peridium crustaceous, like the shell of some small 

 egg, the inner delicate, appearing cinerous to the naked eye, 

 iridescent under the microscope ; columella none ; spores 

 globose, black, '0005 in. in diameter ( = about 13 /x).

Diderma crustaceum, Peck, in 26th Report of State Mus., 

 N. Y., p. 74.

Owing to absence of information respecting the capillitium 

 and presence or absence of markings on the epispore, the 

 position of the species is uncertain.
