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.

[blocks in formation]

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.

[blocks in formation]

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.

Not uncommon

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.

Genus X.

BOVISTA. Persoon.

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.

12 B.

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.

[ocr errors]

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,

Folds simple Not very common. On grass, Rainhill, Cheshire.

Var. B. CORNUTA.

Folds compound branched. In great abundance on the twigs of
Salices, sand hills, Crosby.

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.

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.
