The Myxomycetes of the Miami Valley, Ohio

1. LYCOGALA CONICUM, Pers. Æthalia small, ovoid-conic, gregarious, sometimes close together with the bases confluent, the surface pale umber or olivaceous marked with short brown lines, regularly dehiscent at the apex. The wall thin; the outer layer not continuous, the irregular brown vesicles disposed in angular patches and elongated bands, which have a somewhat reticulate arrangement. The tubules appear as a thin stratum upon the inner membrane; they do not branch, and they send long slender simple extremities inward among the spores. Spores in mass pale ochraceous, globose, minutely warted, 5-6 mic. in diameter. See Plate III, Fig. 5.

Growing on old wood. Æthalium 2-5 mm. in height, the tubules 3-8 mic. in thickness. This is Dermodium conicum of Rostafinski's monograph, but the structure is essentially the same as in the other species. Massee evidently did no
