membranaceous, smooth, whitish ; the mouth small, circular, promi- 

 nent, entire. Stipe short, slender, lacerate-scaly, becoming smooth, 

 with a central pith of long loose threads, finally hollow ; the 

 mycelial bulb small. Threads of the capillitium long, slend r, 

 about as thick as the spores, hyaline, branched ; spores globo-e, 

 minutely warted, pale brown, 4.5 — 5.5 mic. in diameter. 



Growing in rich sandy soil. New Vork, Underwood; North 

 Carolina, Curtis: New Mexico, Wright, Fendler ; Kansas, KelUr- 

 mati] Nebraska, Webber; Colorado, Ellis. Plant 1-2 inches in 

 height, the peridium Y^-% of an inch in diameter, the stipe about 

 Y^ of an inch in thickness. T. brumale, D C. and T. squamosum. 

 Pers. , are said to be synonyms of this species. 



2. T. verrucosum, Morg. n. sp. Peridium depressed-globose, 

 thickish, becoming firm and rigid, with a dense brown cortex of 

 minute persistent scales and warts; the mouth small, circular, 

 prominent, entire. Stipe long, slender, with a surface of brown 

 lacerate scales, internally white, with a central pith of long loose 

 fibers; the mycelial bulb large, irregularly depressed-globose. 

 Threads of the capillitium long, slender, about as thick as the 

 spores, hyaline, branched ; spores irregularly globose, minutely 

 warted, pale brown, 5-6 mic. in diameter. 



Growing on the ground in rich soil in woods. Ohio, Morgan. 

 Plant 2-4 inches in height, the peridium about ^ of an inch in 

 diameter, the stipe nearly y of an inch thick ; the mycelial bulb 

 is sometimes larger than the peridium. It seems altogether differ- 

 ent from T. exasperation, Mont. 



§ 2. Schizostoma. Mouth irregular, lacerate. 

 3. T. FiMBRiATUM, Fr. Peridium depressed-globose, the cortex 

 of minute scales soon falling away, and leaving a smooth brown- 

 ish surface to the thin membranaceous inner peridium; the mouth 

 plane, ciliate-fimbriate. Stipe short, rather thick, the surface 

 brown and scaly-lacerate, white within and fibrillose-stuffed, with 

 a small mycelial bulb at the base. Threads of the capillitium 

 long, slender, about as thick as the spores, hyaline, branched ; 

 spores subglobose, pale brown, minutely warted, 5-6 mic. in diam- 

 eter. 



Growing in sandy soil. New York, Peck; North Carolina, 

 Curtis ; Texas, Wright ; New Mexico, Wright ; Kansas, Kellerman. 

 Plant 1-2 inches in height, the peridium nearly y 2 of an inch in 

 diameter, the stipe scarcely % of an inch in thickness.
