Descriptions
Agaricus campigenus Berk. 1855
Agaricus (Psalliota) campigenus, Berk.; minor, pileo campanulato subcarnoso squamuloso, stipite gracili, annulo latiusculo superiore deorsum incrassato, lamellis angustis postice attenuatis subadnatis. HAB . On the ground, amongst grass, Colenso. Pileus about 1 inch high, campanulate, very obtuse, silky, with a few scattered scales, assuming a reddish hue when dry, rather fleshy. Stem 1.5 inch high, about 2 lines thick, incrassated at the base, slightly furfuraceous, with a broadish ring near the top. Gills rather narrow, attenuated behind, adnexed or slightly adnate. Spores pale red-brown, obliquely obovate. This has much the habit of a Lepiota, but the gills are adnexed and the spores pale, but decidedly coloured. It has not, I believe, been ascertained whether the spores of Leucospori ever change their colour when dry. In such species as A. cretaceus they are never dark; It is however certain that in A. fumoso-purpureus, Lasch., they are sometimes colourless, but possibly from being effete; and I have lately received from Dr Badham A. cretaceus with spores decidedly white, though the gills are as pink as in any dark-spored specimens.

Agaricus campigenus Berk. 1855
Pileus campanulate, rather fleshy, very obtuse, silky, with a few scattered scales, assuming a reddish hue when dry, about 2.5 cm. high; gills rather narrow, narrowed behind, adnexed or slightly adnate ; spores pale red-brown, obliquely obovate; stem 4 cm. high, about 4 mm. thick, incrassated at the base, slightly furfuraceous, with a broadish ring near the top.
New Zealand.
On the ground, among grass.
This has much the habit of a Lepiota, but the gills are adnexed and the spores pale but decidedly coloured (Berk.).
The type specimens are destroyed by insects, hence nothing can be added to the above information. If the gills are adnexed the plant cannot belong to Agaricus (the old Psalliota).

Notes
taxonomic status
Material destroyed by insects, fide Massee 1899, p. 297; no material found, and taxonomic position uncertain, fide Horak 1971b, p. 411. However image of Kew material suggests this may be a much earlier name for Macrolepiota clelandii [JAC]
