C. hiema´lis Bull.—belonging to winter. Peridium obovoid or top-shaped, 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 reddish, after maturity gradually falling away from the upper part; inner peridium thin, submembranaceous, pallid or brownish, dehiscent at the apex by an irregular 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, slender and tapering. Spores globose, even, 3.5–4.5µ in diameter, with a short or minute pedicel.
Growing on the ground in fields and pastures. Peridium 2–4 in. in diameter and 3–5 in. in height. I find this species referred to North America in Saccardo’s Sylloge. It is Lycoperdon cælatum of Fries S. M. Possibly the L. cælatum of Curtis’s catalogue may be this species. Morgan.
