NÁTT ÚRUF RÆÐÍNGURINN 27 SUMMARY Fly Mushroom in Iceland by Slurla Friðriksson University liesearch Institule, Deþartement of Agriculture, Reykjavik. 111 Septeniber 1959 tlie species Amanila muscaria L. was for the first time collected in Iceland at Bjarkarlundur, Reykhólasveit, W. and is consequently the first species of the genera Amanita to be discovered in the country. Although not previously reported by botanists, it is considered possible that tlie mushroom might ltave a wider distribution, especially in the north-eastern part of Iceland; wliere it is believed to have existed even at the beginning of the century. Sonte old Icelandic mushroom names indicate that it might liave been known there at stili carlier times. Previously, the nonexistence of the mushroom in Iceland has been regarded as an argument against the theory, that the mushroom was used by the vikings as a drug to induce their berscrk behaviour. Such an argument, liowever, is substantially weakened by the resent discovery of Amanita in the country.
