Notes

Fig. 9 Despite the poor state of the material (SINCLAIR, Auckland 26.IV.1854) microscopical characters and collection notes justify placing this species in Macrolepiota. The spores are typical of this genus: thick-walled, slightly dextrinoid, with distinct germ-pore, 13-16 X 9-10.5 µ. We suppose that this species was accidentally introduced into New Zealand.

Lepiota exstructa (Berk.) Sacc. 1887

Description

Pileus rather fleshy, campanulate, then expanding, white, surface broken up into warts or concentrically arranged, more or less overlapping, thick scales, white, 2.5-3.5 cm. high,4-6 cm. broad when expanded ; gills very distant from the stem, rather crowded and narrow, white with a tinge of pink; spores hyaline, broadly elliptical, ends very obtuse, smooth, 14-15 x .10 µ; stem 7-10 cm. high, slightly 'thickened at the base, pallid, ring ample, superior.

Distribution

Bay of Islands, Auckland, New Zealand.

Habitat

In meadows, &c.

Notes

A very beautiful endemic species. Examination of Berkeley's type specimen, supplemented by others accompanied by notes and sketches, has enabled me to complete the description. Belongs to the procerus group, and is in all probability edible.
