Descriptions
Crowded upon a brownish spot, often following the direction of the main nerves, minute; cups black externally; disc pale. Asci clavate, rather thick. Sporidia obovate-oblong, 1/2250 of an inch long. Endochrome at length obscurely bipartite.
On the upper side of the living leaves of some Gnaphalium, Colenso.
minuta, extus nigra, maculae fusae inspersa, hymenio pallido, ascis amplis clavatis, sporidiis obovato-oblongis, endochromate demum bipartito.
Ephelina gregaria (Berk.) Sacc. 1889
On the upper surface of the living leaves of some Gnaphalium, Colenso s.n. (type).
Apothecia gregarious, sessile on a superficial epiphyllous thallus, discoid, black throughout when dry, disc convex, 0.5 mm. across, dingy yellow with a brown margin when soaked up; receptacle smooth. Excipulum composed of parallel, septate, brown hyphae, 3 µ wide, paler and more irregularly disposed towards the surface; thallus of interwoven brown hyphae like those of the excipulum, algal cells not seen. Asci cylindric-clavate, 8-spored, rather thick-walled, 75 x 10 µ (100 x 9-10 µ, Massee), apex rounded, not blued by Melzer's reagent; ascospores uniseriate or irregularly biseriate above, ovoid, 11-13 x 4-5 µ, with 2-3 oil bodies, hyaline, perhaps eventually 1-septate; paraphyses hyaline, cylindrical, apex rounded, about 2 µ wide.
Neither the superficial habit not the prosenchymatous excipulum support Massee's interpretation of this as a Pseudopeziza and I cannot at present improve on Saccardo's disposition of it.
On the upper surface of living leaves of a species of Gnaphalium. New Zealand (Colenso, nn. 5056 & 5272).
Erumpent; gregarious or scattered; disc pallid, externally blackish, glabrous, about 1/2 mm. across; cortex parenchymatous, cells small; asci cylindric-clavate, apex rounded, not blue with iodine, narrowed below into a slender pedicel, 100 x 9-10 µ; spores 8, irregularly 2-seriate in the upper part of the ascus, 1-seriate towards the base, hyaline, smooth, elliptical or sometimes inclined to be narrowly egg-shaped, or obovate, 10-12 x 4-5 µ; paraphyses numerous, very slender, tips very slightly or frequently not at all thickened.
This species is a typical Pseudopeziza, and will stand as P. GREGARIA.
Ephelina gregaria (Berk.) Sacc. 1889
ad paginam superiorem foliorum Gnaphalii Nova Zelandia septentr. (COLENSO).
Ascomatibus minutis, maculis brunneolis insidentibus, extus nigris, intus pallidis; ascis latis, clavatis; sporidiis obovato-oblongis, 10 µ. longis, plasmate demum obscuro bipartite.
