ResumoThe stalked cup-fungus Banksiamyces is reported from 13 wild and one cultivated Banksia species. The geographic range of Banksiamyces is expanded to include Western Australia, South Australia, Victoria, Tasmania and NSW. Forty-five collections of Banksiamyces were examined in detail for a range of macro- and micro-morphological characters. Amongst the collections were all four of the previously described Banksiamyces species (B. katerinae, B. maccannii, B. macrocarpus and B. toomansis). Some collections that did not accord with these taxa were assigned to Banksiamyces aff. macrocarpus and B. aff. toomansis. The two species B. katerinae and B. toomansis appeared closer than initially proposed. The strict host-specific relationship suggested by some earlier studies was not confirmed. Evidence is provided for production of the fruit-body in early spring, and production of multiple crops of the same species on the one cone over successive fruiting seasons. Apothecia of these crops are of different macroscopic appearance, with lighter apothecia being mostly immature, and darker apothecia producing spores. This phenomenon may explain previous observations of seemingly different species on the same cone.
