146 NEW OR CRITICAL FUNGI. 



margin and giving it a fringed appearance when seen from the 

 outside, 50-75 x 4-5 /x ; asci narrowly clavate, apex slightly 

 narrowed and tinged blue with iodine, GO-70 x 7-8 /x; 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 /y. ; paraphyses filiform, sometimes branched, 

 containing orange oil-globules. 



Helotium trcibineUoides Rehm. Ascom. no. 853. 



Solenopezia trahinelloides Sacc. Syll. viii. no. 1982. 



Helotiella NuttalUi E. & E. Proc. Acad. Nat. Sci. Philad., Part 

 iii. 1894, p. 351. 



Exsicc. — Rehm'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 Rehm 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, lf-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 [jl, 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 jx; paraphyses cylindrical, hyaline, about 2 /x thick, 

 longer than the asci. 



On rugged bark. Near Dimboola, Victoria, Australia (F. Reader). 



Externally almost indistinguishable from Erinella Nova-Zea- 

 landice. 



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 hypha?, 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 iind translucent, except near the apex, which is paler, or 

 almost hyaline, changing to a clear purple colour when treated
