42 FUNGUS-FLORA. 



walled, septate, slightly tMckened at the septa; spores 

 globose, minutely warted, 5 /a. 



Tuhstoma mammosum, Berk., Outl. 299 ; Cke., Hdbk., n. 

 1069, f. 112; Mass., Mon. Gast., p. 86, f. 33. 



Tuhstoma hrumale, D.O., FI. Fr. ii. p. 269. 



On old walls, dry banks, &c. From 1-3 in. high ; peridium 

 ■i— f in. across, furnished with a minute umbo at the apex, 

 which eventually forms the mouth through which the spores 

 escape ; stem equal, about two lines thick, smooth, or gene- 

 rally furnished with minute recurved scales that are some- 

 times arranged in circles like frills. Whitish when fresh, 

 becoming dirty ochraceous when dry. 



BATTAEEEA. Pers. (figs. 9, 10, p. 28.) 



Volva universal, central layer gelatinous. Peridium very 

 much depressed, bursting through the volva and raised 

 :ibove ground on a long stem ; capillitium present ; columella 

 absent. 



Battarrea, Pers., Syn. Fung., p. 129 ; Mass., Mon. Gast., 

 p. 86. 



The very much depressed peridium, which is concavo- 

 convex in section, with the convex side uppermost, distin- 

 guishes the present genus. 



Battarrea phalloides. Pers. (figs. 9, 10, p. 28.) 



Stem elongated, slightly tapering downwards, hollow, 

 externally broken up into coarse fibres; furnished with a 

 loose volva at the base ; mass of spores yellowish brown ; 

 capillitium threads branched, collapsing, mixed with a few 

 thicker threads having the wall thickened in a spiral manner ; 

 spores globose, minutely warted, 6 jx. 



Battarrea phalloides. Berk., Out!., p. 299 ; Cke., Hdbk., n. 

 1068, f. Ill ; Mass., Mon. Gast., p. 87, f. 29. 



Lycoperdon phalloides. Sow., Fung., t. 390. 



Sandy places and in hollow trees at the base. The plant is 

 at first buried deep in the sand, and enclosed in a volva as 

 in Phallus. After the complete differentiation of the gleba, 

 the peridium is elevated above ground on a long stem from 

 10-14 in. long and ^-| in. thick in the centre. If the fungus 

 is drawn up by the stem, the volva generally remains behind. 

 Peridium 1-lJ in. across.
