On elder and elms. Very common. Our figure is from
specimens on elms which have the surface of the hymenium
freer from folds. I do not, however, consider it a distinct
species.
48. N-^MATELIA, Fr.
Nucleus solid, heterogeneous, covered with a gelatinous
stratum, which is everywhere clothed with the hymenium.
1. N. encephala, F r .; nearly sessile, pulvinate, plicato-
rugose, pale flesh-coloured, then brownish.—Willd. Bot. Mag.
i. t. 4. / . 14.
On pine-rails. Rare. Loch Lomond. Wales, Mr. Ralfs.
Looks like the brain of some animal. Nucleus large, opaque,
white.
2. N. nncleata, F r .; sessile, flat, somewhat gyrose, white,
then brownish-yellow.
On rotten wood. Bare. Sometimes confounded with
Tremella albida, from which it differs in the presence of a
small white nucleus. I see no difference between British and
American specimens.
3. N. viresoens, Cd.; small, roundish, depressed, gyroso-
tuberculate, or quite even, green.—Fl. Dan. t. 1857, / . 1.
On furze-branches. Common.
49. DACRYMYCES, Nees.
Homogeneous, gelatinous. Conidia disposed in moniliform
rows. Sporophores clavate, at length bifurcate.
1. D. violaceus, P r.; small, compact, somewhat compressed,
gyrose, violet.
On trunks of pear-trees. Rare. Relhan.
2. D. deUquescens, Duby; pulvinate, slightly waved and
plicate, yellow.
On fallen pine-hranches. Not uncommon. From a quarter
to half an inch across. Spores triseptate.
3. D. stillatus, Nees ; roundish, convex, at first nearly even,
at length often concave, deep orange ; colour persistent. (Plate
18, fig. 8.)—Grev. t. 159.
On pine-rails. Very common. Smaller than the last.
Spores multiseptate. Generally barren. Ditiola nuda, B. and
Br. Ann. of N at. Hist. ser. 2. vol. ii. p. 267. t. 9. f. 4, is probably
the fertile state of D. deliquescens, not of D. stillatus.
4. D. ohrysocomns, Tul. ; small, yellow, gelatinous, cupshaped.—
Peziza cJirysocoma, Bull. t. 376. /. 2.
On fir-branches. Not common.
50. APYRENIUM, Fr.
Stroma gelatinoso-carnose, fibroso-floccose, hollow, inflated.
Plymenium smooth, when dry oollapso-pubesoent.
1. A. lignatile, Fr.— Grev. t. 276.
51. HYMENULA, Fr.
Effused, very thin, maculæform, agglutinate, between waxy
and gelatinous.
1. H. punotiformis, B. and Br. ; gelatinous, punctiform,
pallid, somewhat undulated; spores elliptic.
On decorticated fir-poles. Batheaston, C. E. B. Dirty-
white or very pale umber, slightly tinged with yellow.
52. DITIOLA, Fr.
Orbicular, margined, patellæform. Hymenium discoid,
gelatinous, at first veiled.
1. D. radicata, jFV. ; disc nearly plane, golden-yellow ; stem
thick, villous, white, rooting.—J . and S. t. 8. / . 6.
