Secotium virescens Massee 1890

Description

Peridium ovate, apex acute, basal portion at first attached to the stem, becoming free and expanding, wall coriaceous, even, smooth and shining, pale green ; stem below basal attachment of peridium short, incrassated, tapering upwards, solid, smooth and even, yellowish at the base; gleba bright ferruginous orange, cavities small, sub-equal and regular, septa thin ; basidia large, clavate tetrasporous, sterigmata slender, elongated ; spores elliptic-oblong, smooth, bright rusty-orange, 18-20 x 7-8 µ.

Notes

Peridium 3 x 2 c.m., stem below basal margin of peridium, -5 c.m. long.
Resembling S. acuminatum in shape, but smaller, and differing in colour, polished peridium, and more especially in the spores. A portion of the type specimen of A. acuminatus sent by Montagne to Berkeley has pale olive, broadly elliptical spores measuring 5-6 x 4 µ.

Secotium superbum G. Cunn. 1924

Collections Examined

Distribution.-Otaki Forks, Upper Otaki River, Wellington, N.Z. (300 m., J. G. Myers, E. H. Atkinson, 8/7/22. Type), Forest Reserve, Whakatikei, Paekakariki, Wellington, N.Z. (45 m., J. G. Myers, J. C. Neill, 16/6/23). Collections in the herbarium of the writer, Nos. 922, 1094.

Description

Peridium azure, sage-green or sea-green, sometimes mottled with pallid spots, conical, apex sharply acuminate, base strongly excavated, truncate, or more frequently margin decurrent, up to 8 cm. high, and 4 cm. wide, at first pruinose, becoming glabrous, polished and slightly viscid; drying dull green or olivaceous. Stipe bright yellow, stout, up to 5 cm. long, and 12 nnm. wide, tapering from base to apex, smooth, shining, hollow; columella slightly thickened at the apex. Gleba ferruginous, cellular, cells 2-4 mm. long, laterally compressed, dissepiments thin. Spores smooth, pallid ferruginous, ovate or elliptical, one end rounded, the other pointed, frequently shortly pedicellate, 14-18 x 6-8 µ, epispore thin.

Habitat

Habitat.-Solitary on the ground in grassy places in the forest.

Latin

Hab.. Solitarii ad terram in locis gramineis.

Notes

The large conical peridium, stout yellow stipe and large smooth spores characterise this species. It closely resembles the following species [Secotium columella], but is separated on account of the shape and large size of the peridium It is a magnificent species, the azure peridium and yellow stipe being very conspicuous. The base of the peridium does not as a rule separate from the stipe, but remains closely pressed to it. This is one of the largest species known, and should be readily determined on this account.

Secotium virescens Massee 1890

Collections Examined

Distribution.-Dannevirke, N.Z. (W. Colenso. Type, in Herb. Kew). Locality unknown (T. Kirk. Specimen in Herb. Kew), Bluff, Southland, N.Z. (J. B. Cleland, 10/6/22. Specimen in Herb. Cleland).

Description

Peridium pallid sage-green, ovate or broadly conical, apex obtusely acuminate, base abruptly rounded, slightly or not excavated, 2-3 cm. high, 2-2.5 cm. broad, coriaceous, glabrous, shining, with occasional longitudinal furrows, margin lacerate, somewhat decurrent; drying dull green. Stipe greyish-white, short (almost obsolete in the specimen examined), about 5 mm. long, hollow, smooth, glabrous, tapering from base to apex; columella slightly expanded at the apex. Gleba ferruginous, cellular, cells regular, laterally compressed, 2-3 mm. long, dissepiments thin, enclosed within a dense purplish-brown layer within the wall of the peridium. Spores smooth, pallid ferruginous, elliptical, ends bluntly pointed, 15-18 -x 7-8 µ (Massee 18-20 x 7-8 µ; Cleland 14.5-16 x 8 µ), epispore thin.

Habitat

Habitat.-Solitary on the ground in rain forest.

Notes

This species is characterised by the colour of the peridium and gleba, short, almost obsolete stipe and the large size of the spores. The plant somewhat resembles the preceding [Secotium superbum]
I am indebted to Dr. Cleland for the loan of the specimen from which the above description has been drawn up. In a note accompanying the specimen he fias given details as to the colour, shape and size of the peridium when collected, and these have been incorporated in the above description.
This species was originally described from material forwarded to Kew by Colenso. It is apparently rare, for, with the exception of one collection made by the late Mr. T. Kirk, Dr. Cleland's plant is the only collection made since the species was described.

Notes

[Notes from Kew Type specimen, PRJ 2010] type not found. Shaun just found a note in Cunningham (1944: 80) that Colenso 722 (the type) is labelled "S. szabolcsiense = S. czerniavii" in Kew. Presumably that is where it remains filed.
