country heretofore has been inchided with A. alropiii purcuin. 

 I have followed Mr. Massee in keeping them separate. This 

 is perhaps L. bicolor, W. tS: C, of the Pacific Coast Catalogue. 



4. L. ATROi'UKi'URKUM, Vitt. Peridium subglobose, 

 often irregular, plicate and lacunose underneath, with a 

 fibrous mycelium. Cortex of slender spines or hairs, long 

 and convergent ab)ve, bjcjming shorter below, gray or 

 brownish above and whitish underneath ; tliese at length fall 

 away, leaving a smooth, shining, pale-brown or pur])lisli sur- 

 face to the inner peridium. Subgleba broad and shallow, 

 scarcely occupying a third part of the peridium, sometimes 

 nearly obsolete ; mass of spores and capillitium olivaceous, 

 then brownish-purple; the threads branched, the main stem 

 about as thick as the spores, with long, slender, tapering 

 branches ; spores globose, distinctly warted, 5.5-6.5 niic. in 

 diameter. 



Growing on the ground in woods. New York, Peck ; South 

 Carolina, Atkinson; Ohio, Morgan; Wisconsin, Trelcasc. 

 Peridium 1-2 inches in diameter. This is possibly the L. 

 nnbrinuni of Schweinitz, N. A. Fungi. 



c. Cortex composed of jninide spinides. 



5. L. CUPRICUM, Bon. Peridium obconic, depressed 

 above and tapering downward, the base plicate, with a fibrous 

 mycelium. Cortex gray or flesh-color, composed of minute 

 spinules circularly arranged and convergent and coherent at 

 the apex ; these dry up, becoming dark purplish in color, and 

 finally fall away from the smooth, shining, copper-colored 

 surface of the inner peridium. Subgleba occupying nearly a 

 third part of the peridium ; mass of spores and capillitium, at 

 length purplish brown ; the threads branched, the main stem 

 thinner than the spores, with long, tapering branches; spores 

 globo.se, distinctly warted, 6-7 mic. in diameter. 



Growing in sandy soil in woods. New Jersey, Ullis. Pe- 

 ridium about I inch in diameter and an inch or more in 

 height. The microscopic features are given from specimens 

 received from Mr. Ellis. 



6. Tv. .\STEROSPERMUM, D. & M. Peridium obovoid or 

 pyriform, the base short and pointed, with a slender fibrous 

 mycelium. Cortex a thin coat of minute .spinules with inter-
