Sporadically it has been found also in other grassy areas (without grazing). Localities: Máriabesnyő (Com. Pest), grassy places at the edge of forest, 19 May 1961, leg. M.

Pest), mountain slope meadow, 6 June 1965, leg. M. BABOS. Data on the occurrence of Agaricus phaeolepidotus (Moell.) Moell. We succeeded in collecting this scarcely mentioned species, too. It ought to be noted that regarding the colour of the pileus there is some difference between the expression "reddish brown" ("rufescens, rufus") of the description of the species and the following statement to be found in the note: (p. 172): "P. phaeolepidota despite several years' observations of numerous fruit bodies always is a constant pure brown". The colour of the numerous specimens collected by us were pure brown and hazel brown. Characteristic is the discolouring of the flesh: when cut turning moderate yellow expecially in the base of the stem, then slowly flesh coloured of fleshy brownish. Smell slightly as ink, possibly hardly noticeable. Herbarial data: Budapest, Kamaraerdő, wood consisting of Fraxinus, Quercus, Eobinia, 16, 23 October, leg. G. BOHUS & E.

Agaricus porphyrizon Orton Correction: The correct date on p. 156 (Bohus, 1969) is 13 Sept. instead of 30 Sept. Edibility of Agaricus xantbodermus Genev. s. str. According to many years of observation PILÂT (1951) found this species always edible in the environment of Karlátejn. He and his family as well as other persons have collected and consumed it in great quantities. My own observations up to now were the same. Therefore we can find in the elaboration of the Xanthodertnus-gvoup by A. xanthodermus the following remark: "savoury as food" (BOHUS 1974, p. 78). There exists, however, a material of typical A. xanthodermus (Budapest, Kamaraerdő, 16 October 1974, mixed wood), that after cooking gave off a strong carbolic smell. Thus not only A. pilatianus is inedible, but seldom also the specimens of A. xanthodermus are unsuitable for consumption.
