5 probably on the consideration that the name hispida was not always unequivocally used during the lapse of time (E. g., the hispida of Ricken is not hispida). In the same work of Bresadola, in which he published the description of L. carinii, the species L. hispida Lasch is also mentioned, showing agreements with L. carinii also in microscopical characters. Several authors maintain the name L. hispida in a correct interpretation. The view of K o n r a d &Maublanc concerning the synonymies is right, since there is no essential differentiating character among these species of a smaller habit than Lepiota acutesquamosa, with cap, ornamented by spinose scales of broad bases. There is only one datum known from Hungary ; about 30 specimens grew on the wet ground of the alderwoods in the Samassa valley in the Mts. Bükk, 1 August 1957. The description of the species : Diameter of cap 1—4 cm ; hemispheroidal then expanding ; densely covered by deep brown, erect, spinose-scales on white base. Scales deciduous in patches from cap of some specimens, yet their place well visible as minute, round spots, — same as on fruitbody of Lycoperdon gemmatum. Brown, floccose veil traces on margin of cap. Gills white, creamy on older specimens. Stem 1,6—4,5 X 0,1—0,3 cm ; brown ; veil covers it as brown fibrils. These fibrils disrupted on lower two-third of stem, declining. Flesh white. Spores hyaline, oval, 4—4,5x2,2 Cystidia absent. Lepiota irrorata Quel. Drosella irrorata (Quel.) Kühner et Maire Grown in numerous specimens in a shrubby site of mixed woods on the Mt. Csúcshegy of the Mts. Buda, 26 June 1956 ; then collected also later in several specimens at the same place, 27 July 1957. Previously, there was only one dubious datum known from Hungary. The description of the species : Diameter of cap 1,5—6,5 cm ; light ochreous, slightly viscid. Gills creamy. Stem 1,6—8x 0,4—0,8 cm ; whitish above, ochreous below. Ring disruptive, rapidly fugacious. Stem ornamented, below line of ring, by fine rusty yellow-rusty brown grains and scales. In wet weather, also shining rusty yellow-rusty brown drops visible. Flesh whitish ; smell somewhat resembling that of Lepiota cristata. Spores hyaline, oval, 4,5—5 X 2,2—3 ju. Cystidia club-shaped 22,5—31,5 X 15—20 fi. Lepiota obscura Locquin n. c. (transitus L. griseovirens — fourquignoni) The green — greenish blue — grey scaly, later brownish — reddish brown discoloring capped Lepiota species are very uniform with regard to their external morphological characters. Romagnesi & Locquin distinguish the four species and one subspecies on the basis of their microscopical features, especially by the shape of the spores, as follows : Lepiota grangei (Eyre) Lange : spore projectile-shaped Lepiota griseovirens Maire : spore projectile-shaped Lepiota griseovirens ssp. obscura Locquin : spore partly projectile-shaped, partly oval Lepiota fourquignoni Quel, sensu Kd. et Mb. et al : spore oval Lepiota cretini Bat.: spore cylindrical, tapering to a tip
