Sporangia minute, either combined to form an sethalium, or closely compacted ; rarely free, sessile, or stalked; sporangium- wall membranous, uniform, beset with microscopic, dark, plas- modic granules. 1. L. Tubulina Fries, (1849). Plasmodium? Sporangia minute, combined to form a more or less complex, effused or pulvinate sethalium, 1 to 10 mm. thick, black with a cortex of imperfectly developed spores, or umber-brown with the surface formed by the membranous walls of the convex summits of the component sporangia; hypothallus strongly developed, of mem- branous, more or less spongy tissue; sometimes the sporangia are shortly cylindrical and closely compacted, sessile, 0'3 to 0'5 mm. broad; in rare instances they are free and shortly stalked; sporangium-wall membranous, yellow-brown, uniform, beset with scattered clusters of dark, round, plasmodic granules, 1 fi. diam. Stalk, when present, short, dark brown, rugose. Spores och- raceous-brown, faintly warted, 4 to 6 ju, diam.—Licea effusa Bhr., Sylv. Myc. Berol., p. 26 (1818).
