Secotium cartilagineum G. Cunn. 1924

Collections Examined

Distribution. Beech Forest, Dun Mt., Nelson, N.Z., 650 m. (J. C. Neill), 27/5/23. Type in herbarium of the writer, No. 1099).

Description

Peridium pallidum, paler below, depressed-globose, base excavated, incurved, margin distinct from stipe, 7-12 mm. high, 18-22 mm. wide, densely and closely scabrid; drying dingy-brown. Stipe short, stout, up to 10 mm. long, 4 mm. thick, tan-coloured, hollow, scabrous, base slightly inflated. Gleba dark ferruginous, cellular, tough, compact, cells minute, 2-3 mm long, polygonal, dissepiments thin. Spores verruculose, ferruginous, ovate, rounded at one end, pointed at the other, 12-15 x 8-11 µ, epispore thin.

Habitat

Habitat.-Solitary on the ground in beech forest.

Latin

Peridio pallido-brunneo, depresso-globoso, base excavato, 7-12 mm. alto, 18-22 mm. lato, scabrido. Stipite 10 mm. longo, 4 mm. crasso, brunneo, excavato. Gleba aurantio-brunnea, . cellulosa, lenta. Sporis verruculosis, flavo-branneis, ovatis, 12-15 x 8-11 µ.

Notes

The scabrid surface of the peridium would place this close to S. scabrosum, but the glebal characters are different from those given for the latter species. In appearance and to the touch the peridium exactly resembles chamois leather. The tough, almost cartilaginous nature of the gleba is also characteristic, and would serve to separate it from any other Australasian species.
