Article: Horak, E. (1980). On Australasian species of Lepiota S.F. Gray (Agaricales) with spurred spores. Sydowia 33: 111-144.
Habitat: Habitat - on soil or on rotten wood, Nothofagus forest - New Zealand
Notes: Remarks. - The most significant features of this species are the large, spurred spores, the fusoid-lageniform
cheilocystidia and the dark brown colour on the carpophores. The combination of these
three characters definitely exclude the speculation that L. calcarata represents a discoloured form of
L. alopochroa (B. & BR.), L. infelix HORAK or some other species belonging to the complex
around L. castanea QUEL. For further discussion see HoRAK (1980b).
L. calcarata shares the dark brown colour of pileus and veil remnants with the Papua New Guinean
L. crepusculata HORAK whose microscopic data, however, are distinctly separating these two
Australasian taxa.

Description: Pileus10-20 mm diam., convex when young becoming broadly umbonate or campanulate, dark brown, umber brown, paler towards the estriate margin, smooth at centre, disrupted to form appressed fibrillose irregular squamules towards margin, occasionally with pale brown veil remnants. Lamellae free, ventricose, moderately crowded, whitish when young turning to yellowish or pale brown, edge concolorous, not fimbriate. Stipe 35-60 x 1.5-2 mm, cylindric or rarely attenuated towards base or indistinctly fusoid, brownish or pale orange-brown, covered with short, irregular, concolorous rings and patches from veil, often washed off in over mature specimens, cortina absent, dry, fistulose. single in groups. Context pale orange-brown in cortex of stipe. Odour pleasant, fruity. Chemical reactions on pileus: unknown. Spores 11-15 x 4-4.5 µm, spurred, hyaline, dextrinoid, smooth, germ pore absent. Basidia 22-28 x 8-10 µm, 4-spored. Cheilocystidia 25-40 x 6-10 µm, fusoid to lageniform. hyaline, thin-walled, forming sterile seam on gill edge. Pleurocystidia absent. Cuticle a palisade of erect cylindric or subfusoid cells (25-140 x 5-10 µm), with brown pigment in membrane, septa with clamp connections.
Habitat: on rotting log of Nothofagus sp. and on soil. New Zealand
