Lepiota rufovelutina Vel. var. sanguinescens Pilât This characteristical, nigrescing Lepiota is identical with the variety described by P i 1 á t in 1955, collected twice around Prague, Czechoslovakia. The identification of fungi collected in the plant association Fageto-Ornetum on the Mt. Szarvashegy in the Mts. Buda, 15 and 29 Oct. 1955, and in a mixed forest on the Mt. Csúcshegy, Oct. 1955, were also done by Pilât. The material is in the Herbarium of the National Museum in Prague. Lepiota sistrata Fr. forma minima Lange n. c. In the past years, we have succeeded to collect the fungus Lepiota sistrata Fr. forma minima Lange, new for Hungary, on 14 occasions, in various deciduous forest associations, as follows : Fageto-Ornetum, Mt. Szarvashegv, Mts. Buda, 31 August, 1955 ; Querceto-Potentilletum albae pannonicum melicetosum, Mt. Samassa, Mts. Bükk ; 18 August 1955, 8 Sept. 1955 ; Querceto-Luzuletum subcarpaticum, 18 July 1955 ; in other frondose plant associations, 20 August 1955, 7 Sept. 1955 ; Querceto-Carpinetum pannonicum, 8 Sept. 1955, 6 Oct. 1955 ; Querceto-Potentilletum albae pannonicum cladonietosum, 19 July 1955, on Mt. Balázshegy ; in deciduous woods, 1 July 1956, prope Stimetz-ház ; in frondose woods, 2 August 1957, Vöröskő valley ; in alderwoods in the Samassa valley, 6 August 1957, 10 August 1957 ; in Querceto-Luzuletum subcarpaticum fagetosum, on the Mt. Nagy Somhegy, in the Mts. Sátor, 17 Sept. 1957. The species Lepiota sistrata is very rare in Hungary, but its above form is also rather rare, according to literature data, in the whole of Europe. This small fungus found in rather large amounts may be identified with the L. seminuda Fr. forma minima of Lange. The question, however, arises whether forma minima could be preserved, since the fungus published by Wakefield &D ennis under the name L. seminuda is also agreeing with the forma minima of Lange, only its measurements are bigger. On the other hand, if we accept the designation „forma", it would be more advisable to accept the form described by Lange as a form of L. sistrata, since, according to the opinion of Konrád & Maublanc and Pearson, L. seminuda is a synonym of L. sistrata. The description of the fungus : Diameter of cap 0,4—1,2 cm ; white, with possibly a slight rosy tint centrally. Covered with white, mealy granules. On margin of young specimens, fugacious, white veil traces. Gills white. Stem very slender, breakable; 1,3—3,5x0,05—0,1 cm; white above, flesh-colored below. Spores hyaline, oval, 3—3,7 X 2—2,3 ju. Cystidia absent. Bibliography: Barbier, M.: Lepiota Fourquignoni Q. et L. ochraceo-cyanea Kühn. (Bull. Soc.
