t48 NEW OR CRITICAL FUNGI. Allied to Ennella lutea Phil., a native of Victoria, but differing in the very broadly rounded apex of the ascus, and the narrowly clavate spores. Scutularia gallica Mass. Ascophore sessile, applanate, fixed by a central point, somewhat fleshy and of a pale brown colour when moist, blackish and rigid when dry ; disc circular, plane or very slightly convex, immarginate, when dry becoming somewhat concave and with a sharp edge, 2-3 mm. across ; hypothecium and excipulum parenchymatous, hyaline ; cortical cells polygonal, 12-15 II diameter ; asci elongated, narrowly cylindrical, apex rounded, narrowed below into a slender, often curved pedicel, 8-spored; spores hyaline, filiform, nearly as long as the ascus, 60-70 X 1'5 II, rather flexuous, arranged in a parallel, slightly twisted bundle in the ascus, continuous, multiguttulate ; para- physes numerous, slender, about 2 /x thick, septate, hyaline, slightly clavate at the apex. On rotten wood in damp places, St. Sauveur-le-Vicomte, Nor- mandy. Specimen in the Kew Herbarium, along with Bulgariella pulla, to which it bears a superficial resemblance, but differs widely in the hyaline, elongated, filiform spores. Ombrophila aterrima Mass. Ascophores scattered or gre- garious, slightly obconic, attached by a narrowed central point, subgelatinous when moist, rigid, horny, and patellate when dry, everywhere black ; disc plane, distinctly marginate, sometimes very slightly umbilicate, glabrous, 3-4 mm. diameter ; excipulum parenchymatous, cortical cells polygonal, 12-16 /x diameter ; asci cylindrical, apex rounded, narrowed below into a slender pedicel, 8-spored ; spores obliquely 1-seriate, hyaline, continuous, smooth, usually 2-guttulate, elliptical, ends rather obtuse, 10-12 x 7 /x ; paraphyses numerous, slender, hyaline, expanding above into a brown pyriform head 6-8 /u diameter. On rotten wood in damp places. Juan Fernandez [Bertero, 1706). A very fine and distinct species, distinguished by the black ascophore, which superficially resembles Bulgaria inquinans in miniature. Scleroderris virescens Mass. (PI. 357, fig. 5). Scattered or in groups of 2-3 individuals, which are then more or less connate at the base, somewhat erumpent, globose and closed at first, then expanding, the irregular margin remaining more or less incurved, glabrous, entirely diugy, olive-green (when dry), about 1 mm. diameter ; substance tough ; hypothecium and excipulum com- posed of very slender, much interwoven, greenish hyphse, which run out at the periphery into groups of larger cells, forming a grumous external layer ; asci stout, subcylindrical, apex rounded, contracted at the base abruptly into a very short pedicel, not at all coloured blue by iodine, 85-95 x 18 /x ; spores 8, irregularly 2- seriate, hyaline, smooth, straight or slightly curved, cylindric- ellipsoid, ends obtuse, basal end usually slightly narrowest, 5-7-
