 rosettes and often forming a ring-like zone at the apex of the sterile 

 basal stratum, finally disappearing almost completely ; endoperidium 

 concolorous, furfuraceous, minutely spinulose. Mouth small, apical, 

 irregular. Gleba white, then fulvous, and finally ash colour, or 

 purplish. Sterile base whitish, cellular, reaching to the apex of the 

 stem-like portion of the peridium. Spores yellow, obtusely verrucose,

 stem-like base, rarely subglobose, or depressed and nearly sessile, 

 always umbonate, generally plicate and lacunose below, and attached, 

 often in pairs, to a white, cord-like mycelium; exoperidium consist- 

 ing of acute, or obtuse spines, each surrounded by a ring of smaller, 

 obtuse warts, which give a net-like appearance to the endoperidium 

 when the large spines are rubbed off or fall away. Mouth small, at

 olivaceous. Sterile base convex, cellular, reaching to the apex of the 

 stem-like base. Spores olivaceous, smooth, or minutely punctate,
