NEW OR CKITICAL FUNGI. 149 



septate, 32-35 x 8-9 /x ; parapbyses numerous, very slender, 

 septate, corymbosely branched at the apex, the tips slightly 

 thickened and tinged green. 



On soft decayed wood. Bethlehem, United States (Schweinitz). 



The present very fine and distinct species is amongst the 

 Schweinitzian species in Herb. Berk., Kew, with the label "Beth- 

 lehem ; herb. Bchweinitz," but without a name by Schweinitz. 

 On the other hand, the name ^' Peziza viresccns?'' in Berkeley's 

 writing is on the paper on which the specimen is mounted. 



Pyrenopeziza Ellisii Mass. (PI. 357, figs. 6 & 7). Scattered 

 or gregarious, erumpent, at first subglobose and closed, then ex- 

 panded, thin and soft, blackish grey, glabrous, ^-| mm. diameter ; 

 externally consisting of irregularly polygonous cells 9-12 /x diameter, 

 which have a tendency to become slightly elongated and parallel to 

 form the minutely fimbriate margin, dark brown ; within the outer 

 dark-coloured marginal cells is a slightly longer series of hyaline 

 hyphae, which give to tlie margin a whitish appearance; asci clavate, 

 apex narrowed and becoming blue with iodine, base narrowed into a 

 long, slender pedicel, usually curved, 90-100 x 10-12 /^ ; spores 8, 

 2-seriate, hyaline, continuous, smooth, cylindrical, ends obtuse, 

 usually very slightly curved and 2-guttulate, 14-16 x 3*5-4 /a ; 

 parapbyses scanty, cylindrical, septate, about 3 fx thick. 



Peziza denigrata Kunze in Ellis, N. Amer. Fung, no. 565. 



On dead culms of Festuca tenella. Newfield, New Jersey, U.S.A. 

 (Kllis). 



Superficially resembling Niptera denigrata J. Kunze, Fung. Sel. 

 no. 180 (= Pyrenopeziza denigrata Kehm, Asc. no. 353); Krypt.- 

 Flora, Disc. pi. 631, figs. 1-5, p. 605 ; Sacc. Syll. no. 1518. 



P. denigrata differs from the present species in having the asci 

 shorter, cylindric-oblong, abruptly narrowed below into a very 

 short pedicel ; parapbyses numerous, tips thickened, and the ex- 

 ternal cells of the excipulum smaller. 



Spragueola Mass. (PI. 357, figs. 8 & 9). Ascophore sub- 

 globose, irregularly nodulose, glabrous, sessile, solid, hymenium 

 covering the entire surface; asci cylindric-clavate, apex slightly 

 truncate, the pore becoming blue with iodine; spores 8, 1-seriate, 

 continuous, hyaline, smooth, elliptical; parapbyses slender, septate; 

 hypothecium formed of slender, hyaline, very densely interlaced 

 hyphfe, which become thicker, much branched, aseptate, and more 

 loosely interwoven at the centre of the ascophore. 



Mitrula Berk. Grev. iii. 149. 



As to what Spathularia crispata Fr. really is, we shall never 

 know, as it has not been described. In first mentioning the name 

 — Summ. Veg. Scand. 347 (1846) — Fries, in contrasting it with 

 S. Jiavida, says, "A priori distiuctissima ! " Fuckel accepts as the 

 species of Fries a Spathularia differing from S. Jiavida ni having 

 slightly difi"erent spores, measuring 48 x 3 /x, whereas his measure- 

 ments for S. Jiavida are 72 x 2 //, (Symb. Myc. 332). Berkeley, on 

 the other hand, considered the New England fungus communicated 

 by Sprague to represent S. crispata of Fries, but, observing that the
