Descriptions
Secotium leucocephalum Massee 1891
Distribution.-Auckland, N.Z. (Berggren. Type, in Herb. Kew), Mt. Lofty, S. Aus. (J. B. Cleland, 4/8/22. Specimens in Herb. Cleland).
Peridium dingy-grey, depressed-globose, somewhat umbilicate, base truncate, excavated, 9-12 mm. high, 20-26 mm. wide, smooth, minutely longitudinally striate, glabrous, margin tardily separating from the stipe; drying pallid brown, surface becoming rugulose. Stipe whitish, slender, 12-25 mm. long, 3-4 mm: thick, attenuate downwards, solid, striate, smooth, polished; columella expanded at the apex. Gleba ferruginous, cellular, cells laterally compressed, up to 3 mm. long, dissepiments thin. Spores verruculose, pallid ferruginous, ovate or ovate-elliptical, commonly lachrymiform, rounded at one end, pointed at the other, 9-11 x 5-7 µ (Massee, 8 x 5 µ), epispore thin.
Habitat.-Solitary on sandy soil.
This species is characterised by the, small, smooth, depressed-globose peridium and long, slender, solid stipe. The lachrymiform spores are also characteristic. The Mt. Lofty collection is undoubtedly the same as the species described by Massee, as it agrees in all characters, save in the size of the spores. The difference in spore measurement is too slight to allow of the separation of these specimens. The solid stipe is a character present only in this and the following species. In shape the plant shows a general resemblance to S. erythrocephalum, but the pallid colour of the peridium, and the verruculose spores separate it.
