II. Peridium deliiscing by an apical mouth, followed by the upper 

 portion falling away in pieces. Sterile base persistent, separated 

 from the gleba by a distinct diaphragm. 



34. L. depression Bon. (= Lycoperdon hyemale (Pers.) Vitt. sec.

Pe. 2-5 cm., yellowish white, then greyish yellow, and finally brownish, 

 obconic, at first rounded at both ends, then flattened on the top, often 

 compressed at the sides, more or less contracted at the base and 

 plicate ; exoperidium consisting of whitish spines united at the apex, 

 intermixed with minute, simple spines and furfuraceous granules, all 

 of which disappear with age and weathering; endoperidium con- 

 colorous, thin above, dehiscing by a well-defined apical mouth which 

 soon extends until the whole of the upper portion of the peridium 

 disappears. Gleba white, then yellowish, and finally fuscous olivace- 

 ous, separated from the sterile base by a distinct membranaceous dia- 

 phragm. Sterile base with large cells, often forming one half of the 

 peridium. Spores olivaceous, globose, 4/i. Capillitium colourless, 

 branched, flexuose, rough, 4 6/x, in diam. Heaths, pastures and hill- 

 sides. Aug. March. Common, (v.v.) 



35. L. candidum Pers. (= Lycoperdon papillatum (Schaeff.) Hollos.)

Pe. 2-5 cm., white, then yellowish, and finally pale darkish brown, 

 globose, or usually depressed, often plicate beneath and continued 

 into a stem-like base attached to the white cord-like mycelium; exo- 

 peridium consisting of white, blunt cruciate spines which adhere to- 

 gether and peel off in patches', endoperidium yellowish, then pale 

 darkish brown, minutely furfuraceous, thin. Gleba olive, then dark 

 brown, with a distinct diaphragm separating it from the sterile base. 

 Sterile base with large cells, about a quarter to a third of the peridium, 

 rarely very small. Spores dark brown, globose, often pedicellate, 

 3-5-4/Lt. Capillitium coloured, sparingly branched, 5-7 p, in diam. 

 Pastures and heaths. Sept. Oct. Uncommon, (v.v.)

 separated from the gleba by a diaphragm.
