Carrots, irrespective of their origin and whether they have been grown conventionally or organically, almost always harbour spores of Thielaviopsis basicola and T. thielavioides on their surface. Infections become visible as dark green mould patches upon prolonged incubation in polythene bags. These moulds produce beautiful asexual reproductive organs which are described here. We also present the first report of the previously unknown ocurrence of repetitious conidial germination in both species.
