or depression about the base of the pedicel in some specimens results 

 from the shrinking of the fleshy layer in drying. 



Ik Mouth ciliate-fimbriate. 



4. G. limbatus, Fr. Outer peridium multifid, the segments 7-10; 

 inner peridium globose or broadly obovoid, somewhat depressed 

 above, pale to dark brown, pedicellate ; the mouth little elevated, 

 somewhat lacerate, ciliate-fimbriate. Columella very large, convex or 

 conic, with a broad flaring base, occupying about a third part of the 

 peridium; threads of the capiilitium, thicker than the spores, brown; 

 spores globose, minutely warted, brown ; 4-5 mic. in diameter. See 

 Plate I., B. 



Growing in the rich soil around old stumps. New England, Frost ; 

 North Carolina, Curtis; Alabama, Peters; Ohio, Morgan; Wiscon- 

 sin, Trelease; Kansas, Cragin. Inner peridium ^-t^ inches in 

 diameter, the expanded segments with a breadth of 2-4 inches. This 

 is the commonest Geaster in the Miami Valley ; I have found as many 

 as thirty plants growing at once around an old oak stump. The inner 

 peridium is usually slightly constricted around the lower part just 

 above the edge of the columella. From the imperfect description of 

 G. radicans, B. and C, it is impossible to tell wherein it differs 

 from the present species. Possibly G. turbinatus Cragin is something 

 different, but we have seen no specimens. 



5. G. Sch^efferi, Vitt. Outer peridium multifid, the segments 4-8 ; 

 inner peridium globose, pedicellate, sooty- white; the mouth some- 

 what prominent, dentate, the teeth fimbriate. Columella globose, 

 with a narrow base ; the threads of the capiilitium brown ; spores 

 globose, brown. 



Growing on the ground in woods. Catskill Mountains, N. Y. , 

 Chas. H. Peck. Inner peridium less than x / 2 an inch in diameter, 

 the expanse of the segments an inch or more. The fresh specimen 

 is figured with the pedicel sunk in the fleshy layer. 



6. G. minimus, Schw. Outer peridium multifid, the segments 7-9; 

 inner peridium ovoid, pedicellate, white to pale brown ; the mouth 

 conic, ciliate-fimbriate, seated in a plane circular disk. Columella 

 slender, nearly obsolete ; threads of the capiilitium thinner than the 

 spores, hyaline; spores globose, minutely warted, brown 3.5-4.5 

 mic. in diameter.
