476 BRITISH FUNGI 



by the tips of the segments only ; endoperidium obpjTiform, stalk 

 short, mouth conical, grooved ; spore-mass brown with a purple 

 tinge. 



On the ground amongst leaves. 



2. Endoperidium sessile or very nearly so. 



G. striatus. — Exoperidium splitting into a \'ariable number of 

 thin portions ; endoperidium globose, surface usually rough with 

 minute projecting points ; mouth conical, fluted ; spore-mass 

 umber. 



On the ground. 



G. lageniformis. — Exoperidium ox-ate-acuminate, splitting into a 

 variable number of sharp-pointed segments ; endoperidium sub- 

 globose, mouth almost ffat, silky, surrounded by a silky zone ; 

 spore-mass umber with an olive tinge. 



On the ground. 



G. mammosus. — Exoperidium splitting nearly to the base into a 

 variable number of portions ; endoperidium pale, mouth conical, 

 surrounded by a pale, narrow silky circle ; spore-mass brown with 

 a purple tinge. 



The exoperidium is hygroscopic, the segments being strongly in- 

 curved when dry, and spreading when wet. Somewhat resembling 

 G. hygrometricHs, but distinct in the prominent mouth surrounded 

 by a pale silky ring. 



On the ground among leaves, etc. 



G. rufescens. — Exoperidium splitting nearly to the base into a 

 variable number of acute segments, reddish ; endoperidium pale, 

 mouth surrounded by minute, somewhat triangular teeth ; spore- 

 mass blackish brown. 



Differs from G. fimbriatus by the mouth being hounded by sub- 

 triangular teeth. 



In woods and pastures. 



G. fimbriatus (PL XXXV, fig. 2). — Exoperidium limp, splitting 

 into a variable number of acute segments ; endoperidium subglo- 

 bose, mouth nearly flat, silky ; spore-mass blackish umber. 



Differs from all other British species in the almost flat, silky 

 mouth without any encircling zone. 



On the ground amongst leaves, etc. 



G. hygrometricus. — Exoperidium splitting into a variable number 

 of acute segments ; endoperidium usually depressed and wrinkled, 

 mouth small, irregular ; spore-mass dark brown. 



Exoperidium hygroscopic, segments rigidly incurved over the 

 endoperidium when dry, expanded when moist. 



Distinguished from G. fimbriatus by the segments of the exo- 

 peridium being incurved when dry. 



On the ground among fallen leaves, etc.
