52 TULOSTOMA. QUELETIA 



basal portion. Gleba without cells. Basidia club-shaped, irregularly 

 scattered on the hyphae, bearing the spores laterally at various 

 levels. Capillitium well developed, attached to the endoperidium. 

 Spores coloured, globose, verrucose. Subterranean, or half buried in 

 the ground, then superficial. 



Tulostoma Pers. 

 (TU'A,O<?, a knob; crro/ia, mouth.) 



Peridium depressed globose; exoperidium, thin, fugacious; endo- 

 peridium membranaceous, thin, dehiscing by an apical aperture ; stem 

 elongate, inserted into a socket at the base of the peridium. Capil- 

 litium well developed, threads hyaline, very long, much branched, 

 attached to the endoperidium, interwoven. Spores coloured, globose, 

 verrucose. At first subterranean, then superficial.

Brumale, pertaining to the winter. 



Pe. 5-10 mm., whitish, then yellowish, globose, or somewhat de- 

 pressed; outer peridium friable, inner peridium smooth, thin, mem- 

 branaceous, papyraceous; mouth small, slightly prominent, scarcely 

 toothed, entire. Stem 2-5 cm. x 2-3 mm., reddish brown, equal, 

 slightly attenuated upwards to the base of the peridium, and sur- 

 rounded by a ball of mycelium at the base, smooth, or more or less 

 fibrillose, concolorous inside, stuffed. Spores pinkish, acutely warted, 

 globose, 4-5/i. Capillitium threads hyaline, branched, thick walled, 

 nodose septate, 4 6/z in diam. Amongst sand, and on old walls.

Queletia Fr. 



(Dr Lucien Quelet, the eminent French mycologist.) 



Peridium subglobose, then prolonged into a stem-like basal portion; 

 exoperidium thin, fugacious ; endoperidium firm, hard, breaking away 

 from the stem-like base and dehiscing by the gradual falling away of 

 the peridial walls from the base upwards. Capillitium sparse. Basidia 

 with one to three, apical, or lateral, shortly pedicellate spores. 

 Spores coloured, globose, verrucose. Subterranean, then superficial.
