The growth rate of vegetative hyphae of colonies of 22 Dichotomomyces cejpii (Miľko) Scott strains was determined on Sabouraud agar, on Sabouraud agar with 2 and 4 % NaCl, on Sabouraud agar with pH 4-11 and on a medium with 1 % peptone and 4-30 % saccharose. Dichotomomyces cejpii strains are a new member of heat resistant fungi. In our experiments hyphal growth was limited only on Sabouraud agar with 4% NaCl. Chlor of orm-extractable metabolites which stopped the mobility of tracheal cilia of 1 day old chick in vitro were produced by eighteen (58.5%) out of 31 Dichotomomyces cejpii strains in the mycelium and by 26 (83%) in the medium. One strain (No. 2268) had ciliostatic activity comparable with the activity of important known mycotoxins.
