Descriptions
Remarks. - The type material of this Ceylonese Lepiota was reexamined by PEGLER (1972: 168) and the New Zealand collections agree sufficiently well to be considered the same species.
L. alopochroa is characterized by the brilliant red-orange or ferruginous colours on pileus and stipe. It has these features in common with three other representatives of Lepiota viz. L. fulvella REA (1918), L. castanea QUAL. (1880) and L. infelix HoRAK. However, L. alopochroa is well separated from these taxa either by smaller spores or different structure and pigmentation of the pileal cuticle (cf. BABOS, 1964: 69).
Macroscopically L. alopochroa is also similar to L. pyrrhaes (BERK. & BR.) SACC. (1887) but the spores of the latter species are distinctly smaller (PEGLER, 1972: 167).
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.
Remarks. - The peculiar green-black colour on pileus and stipe and the rather large, spurred spores are distinctive characters of L. grangei (EYRE). The material gathered in the two New Zealand localities agrees in all details with topotypic specimens from England. Lepiota griseovirens MAIRE (1928), another species with green-olive colours, is separated from L. grangei by its distinctly smaller spores.
According to HONGO (1959: 76) L. ossaeiformispora IMAI (1933: 43) is probably conspecific to L. grangei which means its area of distribution probably covers the whole Eurasian region (VASSILIEVA, 1973: 180).
The above mentioned records from New Zealand and Argentina indicate that L. grangei also occurs in the more temperate zones of the southern hemisphere.
