Bohus, G. ; Babos, M.: Notes on the occurrence in Hungary of Russula species, with regard to their range in Europe

Mycocoenological survey data (Bohus&Babos 1958) : In the course of coenological surveys, it was found in the following associations, that is, forest types, in the Western Transdanubium : Querceto petraeae-Carpinetum mediostiriacum luzuletosum ; in the area of the Hungarian Central Mountains : Querceto petraeae-Carpinetum pannonicum caricetosum pilosae, Querceto petraeae-Carpinetum pannonicum corydaletosum, Querceto petraeae-Carpinetum pannonicum subnudum, Potentillo-Quercetum (petraea. cerris) pannonicum, Potentillo-Quercetum (petraea, cerris) pannonicum melicetosum uniflorae, Potentillo-Quercetum (petraea, cerris) pannonicum poetosum nemoralis, Potentillo-Quercetum (petraea, cerris) pannonicum Cladonia fades, LuzuloQuercetum subcarpaticum Dicranum fades. Russula pectinata Fr. ex Bull, sensu Cke. ssp. pectinatoides (Peck.) n. c. This rare subspecies (rather frequent in France) is rare also is Hungary. The caracteristics of the collected specimens are the yellow base of the stem, that is, its turning to yellow (instead of the coppery red spot or color of R. pectinata), and the cystids — incrustated with yellow grains — on the margins of the cap (fig. 2.). Its flesh turns later slightly peppery, but this character is not constant. These two characteristics (the yellow base of the stem and the granuloso-incrustate cystids), though typical, do not qualify for the criteria of a distinct species, maybe not even for a subspecies.

Széchenyi-hegy, Mts. Buda (Bohus) Moesz (1942), Bohus (1943). Russula pseudointegra Arn. & Gor. It is rare, or not frequent in Europe, with the exception of certain areas. There are only some few data known from Hungary. It is probably more frequent than that, but is many times mistaken for R. lepida. On one occasion, we have also observed Schaeffer's finding, namely, that sulphovanillin will, in rare cases, stain the gill-section preparation first red, then bluish-green to blue. Herb.: in silva, 30 Sept. 1951, Mts. Buda, leg. Korponai; in silva frondosa, 19 August 1951, near Király meadow, Mts. Börzsöny, leg. Bohus. Lit. : Pamuk, Com. Somogy, S z e m e r e (1960). Russula puellaris Fr. The species ranges probably over the whole of Europe, fructifying mainly in pine forests. In Hungary, it occurs in coniferous woods and in the various types of the association Luzulo-Quercetum. A rather rare fungus. Herb. : in the Mts. Buda : in pineto culto, 27 July 1957, Mt.
