 146 NEW OB CRITICAL FUNGI. margin and giving it a fringed appearance when seen from the outside, 60-75 x 4-5 /a; asci narrowly clavate, apex slightly narrowed and tinged blue with iodine, 60-70 x 7-8 fx] spores 8, irregularly biseriate, hyaline, smooth, straight or very slightly curved, oblong- fusiform, 1-septate, not at all constricted at the septum, 10-15 x 3-4 /a ; paraphyses filiform, sometimes branched, containing orange oil-globules. Helotium trabinelloides Kehm. Ascom. no. 853. Solenopezia trabinelloides Sacc. Syll. viii. no. 1982. Helotiella Nuttallii E. & E. Proc. Acad. Nat. Sci. Philad., Part iii. 1894, p. 351. Exsicc. — Eehm's Ascom. no. 853 ; Ellis & Everhart, N. Amer. Fung., Ser. ii. no. 3233. On dry decorticated beech wood, Gomshall, Surrey. Found on the same matrix in Hungary, and on decaying wood of Castanea in the United States. The American fungus described by Ellis & Everhart is identical with the species previously issued by Eehm in his Ascom. no. 853 as Helotium trabinelloides. Peziza Dorcas B. & Br., a Ceylon species, is almost indistinguishable under a lens from the present, but readily distinguished under the microscope by the excipulum being composed of fairly regularly- sized polygonal cells 9-12 /x in diameter. Dasyscypha aurea Mass. Gregarious, sessile but narrowed to a short, stout, stem-like base, depresso-globose and closed at first, then expanded, but the margin more or less permanently erect, thin, 1|~2 mm. across; entirely clear sulphur-yellow, ex- ternally densely villose, hairs crowded, straight or very slightly flexuous, thin-walled, sparsely septate, cylindrical, apex obtuse or slightly pointed, minutely rough, pale yellow, 150-200 x 4-5 /a ; hypothecium and excipulum minutely parenchymatous, cortical cells hexagonal or almost oblong, elongated in the direction from base to margin, 7-9 x 4-5 /a, pale yellow; asci rather broadly clavate, becoming gradually narrowed downwards from the very obtuse, rounded apex, 8-spored, not at all coloured with iodine; spores irregularly 2-seriate, hyaline, continuous, smooth, cylin- drical, ends obtuse, often 2-guttulate, straight or slightly curved, 18-20 X 5 /x ; paraphyses cylindrical, hyaline, about 2 /a thick, longer than the asci. On rugged bark. Near Dimboola, Victoria, Australia {F. Header). Externally almost indistinguishable from Erinella Nova-Zea- landicB. Dasyscypha Eupatorii Mass. Scattered, sessile, closed at first, then expanding until almost or quite plane, sometimes more or less contracted when dry, at other times remaining plane, 2-5 mm. diameter; substance soft and slightly fleshy; hypothecium and excipulum consisting of densely interwoven hyphse, which become arranged in a parallel series to form the entire margin ; externally clothed with cylindrical, 3-7-septate, obtuse hairs, which are some- times rough with external, amorphous particles of lime, dark brown and translucent, except near the apex, which is paler, or almost hyaline, changing to a clear purple colour when treated
