(Sow.) Cups crowded or scattered, sessile, hemispherical; externally brown, paler towards the incurved margin, clothed with short, rigid, septate, brown hairs; hymenium deep flesh-red; asci cylindrical; sporidia 8, fusiformelliptic, 2-guttulate, smooth, 21-25 x 8-10μ; paraphyses not seen. Peziza hybrida-Sow. in "Eng. Fung.," t. 369, f. 1. Peziza brunnea-A. and S., of "Eng. Flo.," v. p. 193; Cooke, “Handbk.," No. 2020; “ Mycogr.," fig. 126, b. On the ground. Cups 2 to 6 lines broad. Sowerby says, "This Peziza resembles P. hispida (i.e. P. hemispherica), and is hairy on the outside, but whiter; the inside partakes of the redness of P. scutellata. We have had it growing two or three years at Mead Place, without any considerable variation" (l. c.). P. hispida (Sow.) has been usually quoted as a synonym of P. brunnea (A. and S.), erroneously, as it now appears, the original specimen having fortunately been found in Kew Herbarium. By the favour of Dr. Hooker we have been permitted to examine it, and have drawn up the above description. B. CUPS SMALLER; HAIRS OFTEN FASCICULATE. (a) Sporida elliptic. 17. Lachnea gregaria.
