or olivaceous, becoming pale to dark brown ; the threads very 

 long, much branched, the primary branches two or three times as 

 thick as the spores, very brittle, soon breaking up into fragments; 

 spores globose, even, 4-4.5 m ^ c - ' n diameter, sessile or sometimes 

 with a short or minute pedicel. 



Growing on the ground in fields and woods. Wisconsin, Brown ; 

 Minnesota, Johnson; Kansas, Kellerman. Peridium 3-5 inches in 

 diameter, sometimes larger. This is Lycoperdon ceelatum, Bull., of 

 Saccardo's Sylloge and of Massee's monograph; it is L. Bovista, 

 Pers. The specimens referred by Trelease to L. favosum, Rostk., 

 probably belong to this species. 



7. C. hiemalis, Bull. Peridium obovoid or turbinate, depressed 

 above, with a stout thick base and a cord-like root. Cortex a thin 

 furfuraceous coat, with stout convergent spines above, whitish or 

 gray, becoming yellowish and rufescent, after maturity gradually 

 falling away from the upper part; inner peridium thin, submem- 

 branaceous, pallid or brownish, dehiscent at the apex by an irreg- 

 ular lacerate mouth. Subgleba occupying nearly half the 

 peridium, cup-shaped above and a long time persistent; mass of 

 spores and capillitium soft, lax, greenish-yellow then brownish- 

 olivaceous; the threads very long, much branched, the primary 

 branches about as thick as the spores, the ultimate ones long, slen- 

 der and tapering ; spores globose, even, 3.5-4.5 mic. in diameter, 

 with a short or minute pedicel. 



Growing on the ground in fields and pastures. Peridium 2-4 

 inches in diameter and 3-5 inches in height. I find this species 

 referred to N. America in Saccardo's Sylloge. It is Lycoperdon 

 ctzlatum of Fries S. M. Possibly the L. ccelatum of Curtis's Cata- 

 logue may be this species. 



8. C. craniiformis, Schw. Peridium very large, obovoid or 

 turbinate, depressed above, the base thick and stout, with a cord- 

 like root. Cortex a smooth continuous layer, very thin and fragile, 

 easily peeling off, pallid or grayish, sometimes with a reddish 

 tinge, often becoming plicate-areolate ; inner peridium thin, 

 ochraceous to bright brown, velvety, extremely fragile, after 

 maturity the upper part breaking up into fragments and falling 

 away. Subgleba occupying about one-half of the peridium, cup- 

 shaped above and a long time persistent : mass of spores and capil- 

 litium greenish-yellow then ochraceous or dirty olivaceous; the 

 threads very long, about as thick as the spores, branched ; spores 

 globose, even, 3-3 5 mic. in diameter, with a minute pedicel.
