Lycop&'don c&paeforme. Bull., t. 403, f. 2 (upper row). 



Bovista capaeforme, Mass., Mon. Gast., p. 65, f. 72. 



On the ground. Distinguished from L. ammopldla, which 

 it resembles in the long, cord-like root, in the globose 

 peridium and smaller spores. 



Lycoperdon pusillum. Fr. 

 Subglobose, slightly attenuated at the base and continued 

 as a long, slender, tapering root ; peridium flaccid, with 

 minute adpressed scurfy squamules, becoming smooth, de- 

 hiscing by a small opening ; mass of spores olive ; capillitiam 

 dense, threads much branched ; spores globose, smooth, about 



Lycoperdon pusillum, Cke., Hdbk., n. 1086 ; Mass., Mon. 

 Lycop., n. 106; Bolt.,t. 117, f. 6. 



Bovista pnsilla, Mass., Mon. Gast., p. 65, f. 59. 



In pastures and on hedge-banks, &c. Our smallest puff 

 ball, ^— f in. across. 



** Spores elliptical. 



Lycoperdon ovalisporum. Mass. 



Subglobose, sessile ; outer layer of peridium whitish, fragile 

 above and falling away, persistent below, inner layer thin, 

 lead-colour, dehiscing by a small opening; mass of spores 

 umber; threads of capillitium much and irregularly 

 branched, tips tapering; spores elliptical, umber, with a 

 hyaline border, pedicels long, stout, 6x4/*. 



Bovista ovalispora, Cke. and Mass., Grev. xvi., p. 46; Mass. 

 Mon. Gast., p. 62, f. 62. 



On the ground. Superficially resembling L. nigrescens, 

 but differs in having no. tinge of pui-ple in the gleba and 

 the elliptical spores. The last character also separates the 

 present species from L. plumbeiim. 



GEASTEE. Mioheli. (fig. 2, p. 28.) 



Peridium at first «n tire, composed of three layers, the two 

 outermost (exoperidium) usually continuous, splitting from 

 the apex into several pointed segments which become 

 expanded ; inner layer (endoperidium) sessile or pedicellate, 

 furnished at the apex with one or more definite orifices;
