Key Identification Features
- The ultimate segments are emarginated, shaped obovate, obcordate, or broadly oblong, are indistinctly areolate, and reach a maximum width of 4–12 mm.
- The distinctive mature discoid carpocephalum is easily recognized; earlier in development it may be more or less low-pyramidal, but it is never lobed, making it quite distinctive.
- Spores are brown, ranging 35-450 um, more or less distinctly tetrahedral, irregularly areolate-lamellate, with a pellucid margin.
- hemisphaerica, and therefore not a distinct species.
