Young plant acute. Exoperidium cut beyond the middle to seven to nine acute segments. In herbarium specimens usually saccate but sometimes revolute. Mycelial layer closely adherent, compared to previous species relatively smooth. (*) Fleshy layer when dry, thin closely adherent. Endoperidium globose, sessile. Mouth sulcate, indefinite. Columella globose-clavate. Capillitium thicker than the spores. Spores small, globose, 4 mc, almost smooth.
     This plant is common around Cincinnati and was referred by Morgan to "striatus." It is a reddish brown plant and differs widely from other species with sulcate mouths previously described in its closely sessile endoperidium. It is the same plant as lageniformis, indeed Bresadola so refers it, excepting that plant normally has an even mouth, and no other species to our knowledge has mouths in both the even and the sulcate series. Still we are convinced of the strong probability of this view and have found in a collection of sulcate mouthed specimens a single specimen with an even mouth. It is quite common in this immediate vicinity growing about old stumps and logs, but has never reached me from any other locality in this country or from Europe.

(*) As in the previous species the mycelium covers the young plant but is not so strongly developed so that the adhering dirt is not so evident on tbe mature plant.
