The cross‐points of conidia of Penicillium piceum were determined by partition in aqueous two‐phase systems. No differences in cross‐points or partition behaviour were registered for conidia subjected to u.v. radiation, 95°C dry heat or 120°C wet heat, compared with untreated conidia. The cultivation of fungi on various types of substrates affected the surface characteristics and thereby the cross‐points of the conidia. When the method was applied to three closely related and morphologically similar isolates in the P. viridicatum group, significant differences were observed between the range of cross‐points for conidia of P. crustosum, P. camembertii group II and P. camembertii group III grown on various media.
