NEW OR CRITICAL FUNGI. 147 with potassium hydrate, 70-120 x 5-7 /*, sometimes arranged in fascicles; asci clavate, apex narrowed and blue with iodine; pedicel elongated, often crooked, 100 x 8-9 />t; spores 8, irregularly 2- seriate, straight or slightly curved, hyaline, smooth, for a long time continuous, finally 1-septate, 12-20 X 3 /* (averaging 15 /xlong); paraphyses hyaline, 2-3 /x thick, almost cylindrical. Peziza Eupatorii Schw. Syn. Fung. 174 (1834). Trichopeziza Eupatorii Sacc. Syll. no. 1758. On dead stems of Eupatorium purpureum, Bethlehem, U.S.A. (Schweinitz). The above diagnosis is drawn up from a specimen named by Schweinitz, and now in Herb. Berk., Kew. The clear purple colour assumed by the external hairs when treated with potassic hydrate is very striking. There is not a single point of specific relationship between the present species and Peziza solenia Peck. ( = Solenopezia solenia Sacc. Syll. no. 1981), as has been suggested. Barlsea subaurantiaca Mass. Ascophore subsessile, con- tracted into a very short, stem-like base ; at first convex and closed, then expanding and becoming plane, the entire margin frequently drooping; disc umbilicate and usually furnished with a few radiating shallow furrows, tan -colour with a tinge of orange ; externally whitish, very minutely scurfy, about 1 cm. across; excipulum formed of densely interwoven, septate hyphaB about 6-7 p thick, cortex pseudo-parenchymatous, and running out into minute, irregular groups of cells that give the scurfy appearance to the outside; asci cylindrical, apex subtruncate, base narrowed into a long pedicel, 8-spored; spores obliquely 1-seriate, hyaline, 1-guttu- late, rather coarsely warted, globose or subglobose, 14 p diameter; paraphyses septate, the clavate tip 7-8 p thick. On the ground. Hamilton, Victoria. Allied in size and habit to Barlma recurva Berk., from Tas- mania, but distinguished by the smaller spores and the orange-yellow disc. Erinella Novae-Zelandise Mass. Gregarious, narrowed below into a short stem-like base, clavate and closed at first, then expanding and becoming pear-shaped, 2-3 mm. across; disc con- cave, pale yellow, externally tawny, densely clothed with septate, obtuse, cylindrical, brown, thin-walled hairs, 60-80 x 4-5 p, usually rough with minute particles of lime ; hairs forming the margin longer and pale, except at the tip ; excipulum parenchy- matous, cells 6-9 p diameter; asci clavate; apex broad and very obtuse, tapering below into a slender, usually crooked pedicel, wall thick except at the apex, 8-spored ; spores arranged in a parallel bundle, very long and narrowly clavate, apex 5 p thick, rounded, and gradually tapering to the pointed base, multiseptate, hyaline, smooth, straight or slightly curved, 85-95 p long ; paraphyses septate, hyaline, not thickened at the tip, 2|-3 p thick. On dead wood and bark. New Zealand. A very beautiful species, superficially resembling Lachnella 'pulverulenta^ but rather larger, and with very different spores, L 2
