Figure 484.—Geaster Archeri.
Young plant acute. Exoperidium cut beyond the middle into seven to nine acute segments. In herbarium specimens usually saccate but sometimes revolute. Mycelial layer closely adherent, compared to previous species relatively smooth. 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 the mature plant. Fleshy layer when dry, thin and closely adherent. Endoperidium globose, sessile. Mouth sulcate, indefinite. Columella globose-clavate. Capillitium thicker than the spores. Spores small, 4 mc. almost smooth. Lloyd.
I first found the plant in the young state. The acute point, which will be seen in the photograph, puzzled me. I marked the place where it grew and in a few days found the developed Geaster. The plant is reddish-brown and it differs from other species "with sulcate mouths, in its closely sessile endoperidium." I have found the plant several times in Hayne's Hollow, near Chillicothe. I found it in the tracks of decayed logs.
The plant has been called Geaster Morganii in this country but had previously been named from Australia.
