Summary:
Features include 1) a scarcely lobed deep olive-buff fruitbody 0.8-4cm across, the surface minutely scabrous or rarely minutely and irregularly verrucose, 2) a spore mass darker than the surface, marbled by a few large venae externae and slender, dark venae internae, and 3) microscopic characters including spores measuring 36-70 x 20-40 microns, very narrow with pointed ends to somewhat broadly elliptic, generally coarsely and irregularly alveolate, with 4-9 x 3-6 alveoli across the diameter, asci that are 1-4 spored, and venae externae sometimes bordered by an interrupted palisade of paraphyses.

Interior:
