White mould on Bolete (Xerocomus sp.)

Hi, I collected some specimens of Xerocomus which were partly and not abundantly infected by a white mould. I expected Hypomyces chrysospermum but when I checked it under the microscope I found a very peculiar morphology. The reproductive parts consisted of a large, bullet-shaped organ encapsulated by some thick wall subtended by a springy and curve conidiophore. 

Any ideas to the genus ?

I searched on the keys/pictorials of ID of Moulds Website and nothing compared
