On the ground in woods. Norfolk. Brijant and Rev. R. B. Francis. 

 Trowse near Norwich, SGwerhj.—Vexy variable in size, the inner 

 coat of the outer per idium often separating and becoming vaulted, though 

 in a less eminent degree than G. fornicatus. Of the figures given by 

 Bryant which I believe belong to the present species, fig. 3 represents 

 an individual with the inner peridium surrounded by a membranous 

 cup separating from the lining of the outer peridium. This accords 

 with the distinguishing character of G. duplicatus, C/iev., which is, I 

 should conceive, not a distinct species. 



**#«* Mouth torn, siibstellate, smooth^ not prominent, sometimes 

 obsolete, 



8. G. hygrometricvs, Pers. [hygrometric Starry Puff ball) ; 

 outer peridium multipartite thick rigid inflexed when dry, 

 imier sessile subreticulate (sometimes nearly smooth) bursting 

 irregularly. Pers. Syn. p. 13.5. Fr. Syst. Myc. v. 3. p. 19 — 

 Lye. stellatum. Bolt. t. 179. BidL t. 238, All.—Lijc. volvam

In sandy woods. Svv-ain's moor, near Halifax, ^o/ton.— Bolton's 

 plant is just the same as that of Schmidel, except that the inner p^eri- 

 dium is shortly pedunculate, on which account it is considered by Nees 

 and Sprengel as distinct under the name of G. BoUonii. I have re- 

 ceived abundant specimens of this fungus from Madeira from the Rev. 

 R. T. Lowe. Bryant's f. 1—9 cannot be this species, as supposed by 

 Fries, who judged merely from his specific character without having 

 seen the figures. Sowerby's Lye. recolligens is probably the true plant, 

 but the representation of the orifice forbids its being cited as synony- 

 mous. The species varies greatly in size, colour, and the surfiice of 

 the inner peridium, which is sometimes reticulated, sometimes nearly 

 smooth. 



74. Bovista. Dill, Puffball. 



Peridium papyraceous, furnished with a distinct bark, which 

 at length peels off, altogether fertile within. Capillitium equal.

1. B. nigrescens, Pers. {blackish PiffbaU) ; subglobose 

 (transversely oblong), peridium papyraceous tough at length 

 blackish-umber, bark even entirely evanescent, capillitium dense 

 purple-brown as well as the sporidia. Pers. Syn. p. 136.
