Abstract. In experimental microcosms, 3 Glomus spp. (2 Glomus spp. and 1 G. macrocarpum) were subjected to heating to over 200 deg C at the soil surface and 70 deg at 5 cm to determine the effect of fire on survival of arbuscular mycorrhizal fungi. Heating reduced the quantity of propagules surviving at the soil surface and the effect declined with depth. While all propagules are likely to be affected by heat, it is argued that the hyphal network is most severely disturbed and probably responsible for declines in density of fungi observed in the field following fire.
