The current article presents information about six species of Agaricus recorded for the first time from Bulgaria: A. albosericeus, A. fissuratus, A. maskae, A. moelleri, A. pseudopratensis, and A. tenuivolvatus.

The genus Agaricus includes saprotrophic species occurring in a variety of ecosystems. Most of them, however, are confined to grasslands. Forty one taxa have been recorded in Greece to date. Some species, although heavily picked for their gastronomic value, seem to appear in abundance while others, which are inedible, seem to be infrequent or rare. As in recent years grass and pasturelands in Greece have been included in “improvement programmes” and subjected to the use of fertilizers, there is concern about the disturbance caused to the habitats of the Agaricus species and consequent changes in the fungal biodiversity. It is obvious that further research on the ecology and particularly the factors governing the fruiting and spreading of Agaricus species is necessary before any concrete conclusions are reached and any conservation measures are imposed.

The genus Cystolepiota is new for Israel. In Israel it is represented by two species: Cystolepiota bucknallii and C. moelleri. Locations, dates of collections in Israel, general distribution, detailed macro- and micromorphological descriptions and illustrations are given.

The species of the genus Chamaemyces present in Israel and their distribution are considered. Detailed data on Chamaemyces fracidus var. pseudocastaneus, new to Israel’s mycobiota, and Ch. carmelensis M. Didukh et S. Wasser, sp. nov. are presented.

The current article presents data about seven species of Agaricus, new for Bulgaria, A. deylii, A. impudicus, A. leucotrichus, A. maleolens, A. mediofuscus, A. spissicaulis, and A. subfloccosus. The specimens were collected from the Forebalkan, Toundzha Hilly Country, Pirin Mts, Mt Sredna Gora, and the Western Rhodopes.
