TULOSTOMA. 41 



subgloljose, sessile, peristome indeterminate, piloso-fimbriate ; 

 spore-mass blackish timber ; spores globose, mintitely warted, 

 3-4 /t. 



Geasfer fimbriatus. Berk., Outl., p. 300, pi. 20, f. 4 (peristome 

 not correctly represented) ; Cke., Hdbk., n. 1076 ; Mass., 

 Mon. Gast., p. 81, f. 77. 



On the gronnd. From 1-2 in. across when expanded. 

 The number of segments into which the endoperidinm splits 

 varies from 5—15 in different individuals, and these remain 

 spread oat almost fiat. 



Geaster hygrometricus. Pars. (fig. 2, p. 28.) 

 Exoperidium split into a varying number of acute lobes, 

 which are rigidly infiexed when dry ; endoperidinm sessile, 

 usually depressed, subreticulate, rarely smooth, dehiscing by 

 an irregular, small apical mouth ; spore-mass dark brown ; 

 columella obsolete ; spores globose, warted, 7—10 fi. 



Geaster hygrometricus, Gke., Hdbk., n. 1078 ; Mass., Mon. 

 Gast., p. 83, f. 70. 



On the ground. Exoperidium hygroscopic, segments rigidly 

 incurved when dry, 2— 3|^ in. across -when expanded. Opening 

 of endoperidium irregular, without a defined peristome ; in this 

 respect resembling some species of Lycoperdon. Distinguished 

 from G. fimbriatus, where the mouth is also indeterminate, in 

 the incurved segments and the much larger spores. 



TULOSTOMA. Pers. (emended), (figs. 3, 4, p. 28.) 



Peridium consisting of two layers, the outer deciduous, 

 inner persistent, dehiscing by a small apical opening, 

 columella absent ; capiltitium present, threads septate, 

 swollen at the septa. 



TulosUma, Pers., Disp., p. 6 ; Mass., Mon. Gast., p. 85. 



Eesembling a Lycoperdon with a long slender stem, dis- 

 tinguished by a groove between the apex of the stem and 

 the septate threads of the capillitium. 



Tulostoma manunosam. Fr. (figs. 3, 4, p. 28.) 

 Peridium subglobose, smooth, mouth small, prominent, 

 entire; stem thin, equal, more or less squamulose; spore- 

 mass dirty cinnamon ; threads of capillitium colourless, thick-
