number of acute segments, inner stratum disappearing ; 

 eudoperidium subglobose, sessile, peristome piano-conic, 

 silky, striate, surrounded by a silky zone ; spore-mass umber 

 with olive tinge ; columella clavate ; spores globose, very 

 minutely warted, 3-4 /x. 



Geaster lageniformis, Vitt., Mon. Lye., p. 160, t. i. f. 2; 

 Mass., Mon. Gast., p. 84, f. 75. 



On the ground. Superficially resembling G. MicJielianus, 

 but at once distinguished by the silky zone surrounding the 

 peristome, sessile endoperidium, and smaller spores. 



Geaster mammosus. Chev. 



Exoperidium split nearly to the base into a varying 

 number of acute segments ; endoperidium sessile, pale ; 

 peristome conical, acute, fimbriato-ciliate, surrounded by a 

 pale, narrow, silky circle ; spore-mass dark brown with 

 purple tinge ; columella short ; spores globose, warted, 4-6 p..

 Mass., Mon. Gast., 81, f. 78. 



Lycoperdon recolligens, Sow., Fungi, t. 401. 



On the ground. Exoperidium hygrometric, the segments 

 being much incurved when dry ; 1-2 in. across when 

 expanded. Somewhat resembles G. hygrometricus, but distinct 

 in the presence of a columella and prominent peristome 

 surrounded by a pale, silky ring. 



Geaster rufescens. Pers. 



Exoperidium rigid, thick, split nearly to the base into a 

 variable number of acute segments which become revolute ; 

 endoperidium sessile, subovate, pale, peristome dentate; 

 spore-mass blackish brown ; spores globose, warted, 3-5 yu,. 



Geaster rufescens, Berk., Outl., p. 300 ; Cke., Hdbk., n. 1077 ; 

 Mass., Mon. Gast., p. 82, f. 79. 



In pastures and woods. From 24 in. across when ex- 

 panded, resembling most closely G. fimbriatus, but dis- 

 tinguished by the peristome being surrounded by sub- 

 triangular, pointed teeth, and in the segments of the thick 

 exoperidium being revolute when dry. 



Geaster fimbriatus. Fr. 



Exoperidium flaccid, split into a variable number of acute 

 segments, inner layer soon disappearing; endoperidium
