Geoglossum tremellosum-Cooke, "Mycogr.," fig. 347. Geoglossum microsporum, var., tremellosum-Cooke in "Grevillea," iv. p. 109. On the ground. Name-Tremulus, trembling; from shaking when agitated. Rannock, N.B. (Dr. Buchanan White). Sessile, effused like a crust, afterwards bullato-inflated, determinate, hymenium occupying the upper surface; under side furnished with root-like fibrils; flesh firm, persistent; asci cylindrical; sporidia 8, large. (Plate II. fig. 10.) On the earth or on wood. Large (from 1 to 3 inches), persistent. Name-pia, a root; from the root-like fibrils which clothe more or less of the under surface, attaching it to the ground. 1. Rhizina undulata. Fries. Effused, undulate, bay-brown; margin inflexed, flocculose beneath, and pallid; asci cylindrical; sporidia 8, fusiform, sub-acute, 2-guttulate, at length pseudoseptate, 30-35 x 9μ; paraphyses filiform, enlarged and brown at the apices, which adhere firmly together.

On gravelly and sandy soil that has recently been exposed to fire. Varying in size from an inch to 3 inches broad. At first orbicular, plane, with a whitish margin; when mature convex, undulate, and irregular in outline. The rhizinæ are coarse fibres occupying the greater part of the under surface, but absent for a certain distance from the margin, which is tomentose and rufous; when dry the hymenium becomes black and hard. The fusiform sporidia have a thick epispore, especially at the extremities, and are faintly coloured. The paraphyses adhere by their summits being apparently held together by a brownish "gelatina hymenia," and at intervals occur some which are brown throughout their whole length, and non-septate. These deserve more careful examination in the fresh state, as their function may be to convey from the subhymenial tissue the brown gelatina hymenia" alluded to above. 66 Name Undulatus, waved. Ascot Heath (Mr. Frederick Currey). Wrekin, Shropshire ! 2. Rhizina lævigata. Fries. Orbicular, even, brown; margin prominent, granulose beneath; fibrils pallid; asci cylindrical; sporidia 8, fusiform, acuminate, bi-guttulate, uni-seriate, hyaline; paraphyses filiform.

Exs.—Winter, “Fungi Eur.," 2406; Dr. Cooke, On Stumps"; Fries, "Ad terram araneosam." Scarcely exceeding 1 inch in breadth. The only British specimen I have seen is from Glamis, N.B., which has sporidia in no way differing from R. undulata. Name-Lavis, even; from the even hymenium. Order II. PEZIZÆ. Receptacle concave, plane, or convex, sessile or stipitate, fleshy or waxy; hymenium on the upper surface; asci fixed, cylindrical, or clavate; sporidia usually 8. Receptacle adfixed by the centre, rarely by the whole under surface, or supported on a stem, more or less concave, often becoming plane or even convex; substance fleshy or waxy, not gelatinous or cartilaginous; asci not ejected; sporidia hyaline. Differs from Helvellacei by the concave or plane receptacle; from Ascobolo by the fixed asci; from Bulgariæ by not being gelatinous or subcartilaginous; from Dermatea by the softer texture; and from Patellaria by colour, texture, and form. Name-Pezica (from Téa, the foot, bottom, base, that which rests on its base, sessile), a word used by Pliny to denote various kinds of puff-balls (vide Houghton, "Ann. and Mag. Nat. Hist.," 1885). The name has now acquired a widely different meaning. Fleshy, for the most part large; sporidia large Peziza. 2. Fleshy, or rarely waxy, sessile; sporidia minute Mollisia. 171 3 Hymenoscypha. Chlrosplenium. 3. Stem absent, or short and thick; sporidia simple, rarely 1-septate or 4.

(Hymenium not setulose SERIES I.-NUDE. Fleshy or fleshy-membranaceous, externally glabrous, pruinose, or floccoso-furfuraceus. GENUS I.—PEZIZA. Dill ("Gen.,” p. 74). Receptacle marginate, cup-shaped, at first closed, afterwards expanding; epidermis thin, contiguous, glabrous, pruinose, or floccoso-furfuraceus, persistent, distinct; asci large, distinct, fixed, enclosing 8 sporidia, which are soon elastically ejected; paraphyses filiform, intermixed with the asci. Cups adfixed by the centre, often stipitate, freely unfolding, more or less concave, often becoming plane; hymenium smooth (not villous or pulveraceous), differing in colour; substance fleshy-membranaceous, not waxy or gelatinous.
