Figure 488.—Geaster mammosus.
Exporidium thin, rigid, hygroscopic, smooth, divided almost to the base into about ten linear segments, often umbilicate at the base; inner peridium globose, smooth, sessile, furnished with a conical, even, protruding mouth, seated on a definite area.
Columella short, globose, evident (though distinct in mature plants).
Capillitium simple, tapering, hyaline, often flattened, slightly thinner than the spores. Spores globose, roughened, 3–7 mc. Lloyd.
This plant is found in the woods from July till late in the fall. It differs from G. hygrometricus by its even, conical mouth. I found specimens several times in Haynes's Hollow.
Geaster velutinus. Morg.
