Investigations into the biological and integrated control of basal rot of Narcissus caused by Fusarium oxysporum f. sp. narcissi, identified a number of soilborne antagonists (Beale, 1987). Among the most effective of these antagonists was the bulbilliferous basidiomycete Minimedusa polyspora (Hotson) Weresub and LeClair. Interestingly, this fungus was isolated from a Narcissus-growing soil which was identified as being disease-suppressive and was the first record of the biological control potential of this organism. Previous studies with species in the genus Papulaspora Preuss, to which M. polyspora was first assigned, have identified antifungal properties (A1-Hashimi and Perry, 1986; Shukla et al., 1977), but M. polyspora does not appear to have been considered previously.
