Notes

293. X A Naucoria semiorbicularis (Fries) (4,8,16) = Agrocybe semiorbicularis (Fries) Fayod

Although the material (BERGGREN 61) is half destroyed by insects all the diagnostic microscopical characters of this European species were found. It is apparently an introduced fungus in New Zealand.

Naucoria semiorbicularis sensu Massee 1899 [1898]

Description

Pileus hemispherical, then expanded, even, glabrous, slightly viscid, at length rivulose, tawny-ferruginous, ochraceous when dry, 2.5-5 cm. across when expanded; flesh thin, whitish; gills adnate, rarely more or less sinuous, very broad, crowded, pallid, then rusty - orange ; spores elliptical, 10 x 5-6 µ; stem 5-10 cm. long, 2-4 mm., thick, tough, nearly straight, pale-ferruginous, shining, base usually darker, hollow, the cavity containing a free strand which readily splits into fibrils.

Distribution

Waitaki, New Zealand. Australia, India, Europe, United States.

Habitat

Among short grass, &c.

Notes

Allied to Naucoria pediades, from which it is readily distinguished by the viscid pileus, broad gills, and rusty or ferruginous stem.

Psilocybe sp. 2 Watling & G.M. Taylor 1987

Notes

As Agaricus semiorbicularis, Waitaki, Berggren 61 (K). Badly consumed by insects. Only the following microscopic data was obtainable;

Cheilocystidia absent. Basidiospores 11-12 x 6.5-7(-7.5) µm, smooth, thick-walled with truncate germ-pore, sometimes with dark inclusions. Pileipellis filamentous. Neither cheilocystidia nor pleurocystidia could be found.

This belongs to Psilocybe; see comments above. We do not agree with the placement by Horak (197ib).

An illustration in E apparently is a copy by M. C. Cooke of a Berggren collection labelled 'AGARICUS (GALERA), on the ground, New Zealand'. It is impossible to go any further but it is not unlikely that this figure depicts one of the above collections of Psilocybe.
