Of these species, L. grangei is very distinct by its big, projectile-shaped spores and the double (brown and green) pigmentation of the fibrils of the cap. The spore measurements of the three other species and one subspecies are more or less conforming, and their separation on the basis of the spore shapes is difficult, due to transitions among the species. The connections of these species may be illustrated by the following diagram : griseovirens Maire obscura Locquin n. c. ( tr. griseovirens-fourquignoni) fourquignoni Quel, sensu Kd. et Mb. et al. cretini Bat. If the assumption of Konrad&Maublanc, namely, that the species L. cretini is a synonym of L. fourquignoni, will become validated the above connection will take a linear shape. The above relation establishes so near a relationship that it will be necessary to relegate L, fourquignoni, placed up to now by some authors far from L. griseovirens into another section (Ovisporae), among the other green Lepiota species (L. grangei, griseovirens) . Failing that, L. obscura standing between L. griseovirens and L. fourquignoni, should be transposed into both sections, that is, the one embracing projectile-shaped spores (Stenosporae), and the one containing oval spores (Ovisporae), since our present examinations found both projectile-shaped and oval spores in almost identical proportions within the same preparation. Indeed, the previous consideration of Barbier (1934) may again come to the fore, inasmuch species reductions within the Lepiota group of species discoloring from this special green hue to brown and reddish brown may also be brought about — due to the very slight differences — in the course of future investigations. There are two home data known of Lepiota obscura; one of them is based on the collectings of L. Szemére in 1952 from Pamuk (Com. Somogy). This fungus was, at that time, identified by C. Furrer — Ziogas as Lepiota grangei, but it differs from that species by its small spore dimensions, nor could the double pigmentation of the fibrils of the cap be noticed. The other datum is our own. We have studied four specimens in their habitat in the alder woods in Kishuta in the Mts. Sátor, 16 Sept. 1957. The description of the species : Diameter of cap 0,8—2,2 cm ; convex then expanding, somewhat humpy ; basic color whitish-greyish-rufous, closely covered by grey scales of a greenish tint. Locally, also scales reddish-brown, especially on older specimens. Gills dirt-whitish — grey-whitish. Stem 1,3—4x 0,15—0,25 cm ; whitish above, ornamented below (up to floccose ring-like line) by pattern identical with colour of scales of cap. Spores hyaline, projectile-shaped and oval. A small appendix on some of oval spores. Their measurements : 7,2—8,2 (9) X 3—3,7 //. No cystidia found. In this regard, the are no data in the description of Pilât either.
