On modelling clay.

Occasionally on common black modelling clay, where, to the artist, it is a troublesome intruder, it being generally necessary to work the part again to get rid of it. It is held to the clay by very fine attenuated cobweblike fibres from the sides, as it were, to assist the little knotty root (Sowerby).

The Rev. M. J. Berkeley, in whose possession Sowerby's original specimens were, kindly gave me some of the modelling clay on which the Peziza had grown, but the Peziza had long since disappeared. On the surface of the clay, when it came into my hands, were a number of small, hard, seed-like bodies partly imbedded, around some of which was a growth of mould giving them the appearance of Sowerby's figure. I have kept the clay damp under a bell-glass for some years, but no Peziza has appeared.

GENUS II-PSILOPEZIA. Berk., "Outl.," p. 373.

Indeterminate, immarginate, agglutinate; hymenium always exposed. (Plate V. fig. 23.)

The typical representative of this genus has only been found once. It resembles a Rhizina more than a Peziza, though at first included with the latter, but it has not the peculiar roots of the former. The spores differ also from those in Rhizina.

Two species

A. HYMENIUM MOUSE-BROWN.

1. Psilopezia Babingtonii. Berk.

1-2

Small, convex above, mouse-brown, fixed by the margin; beneath concave, pale watery brown, slightly rugose, with obsolete fibrils; asci cylindrical; sporidia 8,

broadly elliptic, 18-20 × 10-12μ; paraphyses linear, clavate at the apices. (Plate V. fig. 23.)

Peziza Babingtonii-Berk., "Ann. Nat. Hist.," No. 554. Psilopezia Babingtonii-Berk., "Outl.," p. 373; Cooke, "Handbk.," No. 2162.

On rotten wood.

Cup an inch or more broad, contracting greatly in drying, irregular in outline, convex above, mouse-brown; concave beneath, and slightly wrinkled, pale watery brown, fixed by the border; asci linear; spores broadly elliptic; paraphyses linear, their apices clavate (B. and Br., l. c.).

Name After the Rev. C. Babington.

Grace Dieu Wood, Leicestershire! (Rev. C. Babington).

B. HYMENIUM GREENISH-BLACK.

2. Psilopezia myrothecioides. B. and Br. Sub-orbicular; margin laciniate, tomentose, pallid yellow; hymenium greenish-black; asci linear; sporidia 8, elliptic, margin pellucid, 17—19 × 10—13μ; paraphyses filiform, broadly clavate and brown at the apices. Psilopezia myrothecioides B. and Br., "Ann. Nat. Hist.," No. 1489, t. ii. f. 5; "Grevillea," iii. p. 122. On Prunus padus.

Two to five lines broad. The asci are cylindrical, 200μ long, 17μ broad. The clavate apices of the paraphyses are 10 to 13μ broad, and brownish. The cells of the excipulum are 20 to 30μ broad.

Name Myrothecium, a genus of fungi, doç, likeness resembling a Myrothecium.

New Pitsligo (Rev. J. Fergusson).

GENUS III.-HYMENOSCYPHA. Fries.

Opening freely, naked, glabrous; cup thin, membranaceous, but sufficiently firm, supported by the slender sub-equal stem; hymenium distinct; asci large, clavate

or cylindrical; sporidia often in two rows; texture fibroso-cellulose. (Plate V. figs. 24-27.)

Growing on twigs, fruit, and very often on stems of plants (Fries, "Sys. Myco.," ii. p. 117).

Name-vuv, a membrane, and okúpos, a cup; from the membranaceous character of the cup.

Epiphytal, having no distinct sclerotium

SUBGENUS I-SCLEROTINIA. (Fckl., "Symb. Myco.,"

p. 330.)

Cup rather large, or rather small, long stemmed, arising from a sclerotium, more or less infundibuliform, fleshy, marginate, at length more expanded, for the most part glabrous; asci elongated, 8-spored; sporidia ovate, oblong-ellipsoid, hyaline, guttulate, continuous; paraphyses filiform (Fckl.).

A. SPORIDIA ELLIPTIC.

1. Hymenoscypha tuberosa. (Bull.)

Cup thin, at first pyriform, then infundibuliform, at length expanded, bright brown, margin entire; stem elongated, flexuous, more or less immersed in the earth, arising from a black difformed sclerotium; asci cylindrical; sporidia 8, elliptic, biguttulate, 15 × 7μ; paraphyses filiform, rather stout.

The cups are about 6 to 8 lines broad. The disc is generally darker than the exterior; the stem is usually black and fibrous below; the sporidia have a nucleus at each pole; the paraphyses are sometimes branched.
