., a biotrophic mycoparasite of spp.

is newly reported from the centre of origin of in South Africa, where it is associated with dead flower stalks of . , a rare hyphomycete with a morphology corresponding to asexual morphs of , was isolated as mycoparasitic on , along with bacteria that co-occurred in synnematal heads of Germinating conidia of were observed to parasitise germinating conidia of . Although could not be cultivated on its own, the association with proved to not be restricted to , as it could also be cultivated with other spp. is a member of , an order of obligate insect parasitic microfungi. The exact role of the bacteria in synnematal heads of remains to be further elucidated, although one bacterium, , appeared to cause lysis of the synnematal conidial cell walls This discovery suggests that many unculturable obligate biotrophic microbes can probably be cultivated if co-cultivated with their respective hosts.
