9 L. GEMMATUM. Batsch (Micheli).
None of the authorities quoted by Fries appear to give at all distinctly the typical form of this most variable species. Batsch has no plate of it, and refers to Micheli as his authority ; Bolton's plate, exclusive of figs. a and c, represents forms totally unlike each other. "Bulliard champ. p. 143, melior pars," is a reference of no practical use. Happily, some of the varieties are better defined.
Peridium sub rotund, beset with scattered sub-spinulose warts; stem elongated, sub-plicate at the base. Not very common. In plantations, borders of fields, &c. Knowsley, Bromborough.
Var. B. L. PERLATUM. Persoon.
Peridium rounded, somewhat depressed, warts strongly prominent, pointed, at length deciduous; stem round, subscabrous. Very common, sometimes crowded and gregarious in prodigious numbers. Uuder or near trees.
Peridium top-shaped, sub-stipitate, rough, with firm, spurious, sub-distant warts.
Var. 8. L. HIRTUM. Micheli.
Peridium turbinate, hairy, with thin, soft, at length generally blackish warts.
The preceding varieties, with many intermediate forms, are common in grassy places on the coast. Colour generally yellowish or deep umber.
Var. e. L. PAPILLATUM. Schæfr.
Sub-rotund, sessile, papillary, furfuraceo-pulverulent. A form well agreeing with this description, and which is certainly not L. pusillus (Batsch.), occurs frequently in old pastures, and is nearly always solitary.
8 L. PYRIFORME. Schæff.
Peridium sub-pyriform, opening by the somewhat prominent apex; collumella conic. Varying in colour from light to deep rich brown; the slender warts also vary, and are sometimes nearly obsolete.
on stumps: generally in crowded tufts.
9 L. SACCATUM. Schum.
Peridium somewhat depressed above, sub-concave or vaulted beneath, in substance like tissue paper, wrinkled, rather shining, greyish; epidermis almost altogether fugacious, but leaving a roughness on the peridium. The above is a description of a single tufted specimen, five inches in height, found in Knowsley Park in 1856.
10 B. NIGRESCENS. Persoon.
Peridium sub-rotund, 1-2 inches or more in diameter, oblong, often irregularly indented, in age stiff and persistent, variously shaded with brown and blackish tints. Spores globose, pedicellate from the sporophores which remain attached to them. Warren, New Brighton.
11 B. PLUMBEA. Persoon.
Less than an inch in diameter, rotund, in age less hard than the preceding, lead or slate coloured. Hoylake, Southport.
Peridium perfectly flexible, rotund or oblong, one inch in diameter, white, at length pale brown: epidermis thin and very fugacious, but remaining on portions of the peridium in simple or ramose stars : spores pedicellate. B. tunicata. Fries? A few specimens occurred in pasture, Knowsley Park.
SECTION IV. MYXOGASTRES. Fries.
Genus XI. LYCOGALA. Micheli.
1 L. EPIDENDRUM. L.
Peridium sub.globose, from the size of a pea to that of a hazel nut, often crowded and confluent, variously coloured, sometimes bright scarlet, and very beautiful, in age pale or dull-brown. Not uncommon. On palings, Childwall; on stumps and timber in many places.
Genus XII. SPUMARIA. Persoon.
2 S. ALBA. Bull,
Generally somewhat less than a walnut, frothy white; in maturity forming tube-like cells or folds.
Var. a. LAMINOSA.
Folds simple Not very common. On grass, Rainhill, Cheshire.
Var. B. CORNUTA.
Folds compound branched. In great abundance on the twigs of
Genus XIII. RETICULARIA, Bull.
3 R. MAXIMA. Fr.
Forming effused masses thick and broad as the palm of the hand, or even larger, at first mucilaginous, white, opaque, surface variously tuberculate, in age almost wholly transformed into a mass of purple brown spores. Cheshire, I. Byerley, Esq. Almost filling up a rat's hole at the root of a tree in my garden, Rainhill.
4 R. UMBRINA. Fr.
Peridium very thin, shining with a silvery lustre; Aocci branched, mass of spores dark umber. On stumps and timber, an inch or more in breadth, not uncommon. At the base of a dying oak tree, Knowsley; a foot in height, and spreading irregularly for many inches in breadth.
Genus XIV. ETHALIUM. Link.
5 Æ. SEPTICUM. L.
Peridium intermediate, irregular in size and shape; substance very porous, bright yellow. On decaying stems of grass. Carr Mill Dam.
Genus XV. STEMONITIS. Gleditsch.
6 S. OVATA. Pers.
Peridium oval, fugacious, bluish, stem a line or more in height Resembling a Physarum, but the columella is distinct. Fallen branches. Knowsley.
Genus XVI. ARCYRIA. Persoon.
7 A. PUNICEA. Pers.
Crowded, a line or more in height, peridium sub cylindrical, very fugacious; the capillitum beset with spores; colour a very peculiar red, approaching vermilion. A lovely little plant. On decayed wood. Rainhill, Croxteth, Eastham.
8 A. INCARNATA. Persoon,
Capillitium flesh coloured, almost stemless. I have not seen the peridium. Bromborough Wood.
Genus XVII. PHYSARUM. Pers.
9 P. NUTANS.
P. AUREUM. Grev.
Genus XVIII. DIDERMA. Link.
10 D. VERNICOSUM. Pers.
Crowded, sub-pyriform, shining bay, inner peridium paler; spores dark. About a line in height. On fallen twigs. Halsnead.
Genus XIX. DIDYMIUM. Link.
11 D. SQUAMULOSUM. A. & S.
Pileiform, shortly stipitate, covered with the whitish grey, farinaceous remains of the outer peridium. On decaying leaves and twigs of Ulex. Warren, New Brighton.
12 D. FARINACEUM. Schrad.
Peridium sub-globose, mcaly. On fallen branches, Knowsley.
13 D. NIGRIPES. Link.
Stem setaceous; much larger than in the preceding species. On fallen branches. Pexhill.
Genus XX. TRICHIA. Hall.
11 T. PYRYFORMIS. Hoffm.
Peridia pyriform, dark testaceous, growing in scattered groups on rotting wood. Croxteth, Rainhill.
Peridia club-shaped, yellowish; stem, and sometimes the base of the peridium rough. On stumps, Woolton Wood, and rather common in woods in Cheshire.
16 T- TURBINATA. With.
Resembling the preceding species, but sessile. Croxteth, on a fallen branch.
