Stromata epiphyllus, linear and irregularly arranged, about 150/* wide, composed of irregularly radiating threads. No. 31. Actinodothidopsis coprosmae Stevens n. sp. Stromata subcuticular, clypeate, consisting of a compact, black mycelial mass between the cuticle and the epidermal cells, usually about 20 At thick, numerous, dense, thick, mycelial masses extend downward from the stromata between the epidermal cells and considerable ways into the mesophyll. Locules globose, distinctly ostiolate, 80-150/* in diameter, often widely separated, developing below the clypeate stromata, between it and the palisade cells; thin-walled on the bottom and sides. Paraphyses filiform. Asci 8-spored, 29-43 by 18/*. Spores 22-25 by *, obtuse, i-septate (possibly 3-septate), very pale chlorine-green. (See PI. II, B; fig. 4.) On Coprosma sp. Kauai: Waimea canyon, upper pipe trail, June 15, no. 457. ;&fcM%. P1GURE4.—Actinodothidopsis coprosmae (No. 457) on Coprosma: a, portion of a stroma viewed from above, showing several separate perithecia; bf myce- lial structure of the edge of a stroma; c, showing position of the stroma below the cuticle; d, spores; e, the clypeate stroma and three locules. This fungus resembles the Hemisphaeriales in the general character of its stroma, but the perithecium is not dimidiate, but globular, and the stroma is not radiate, though it verges toward radiate character, fig. 4,6). In this family its affinities would be nearest to the Stigmateaceae on account of sub-cuticular development, though differing from this group in not.
