I was searching mushrooms in an afforested area with Eucalyptus gomphocephala. Ground covered with leaf litter, twigs, branches and fruit of these trees. The fallen and decaying fruit were colonized by a white mould which mostly was composed of a Penicillium species (and also some Verticillium-like species). Have aanyone met this Penicillium and know what it is? The interesting part is that it is specific to the fruit!


Spores are clumped in heads which are liberated when there is water. I saw this under the microscope (toplight illumination) where there was like a river of spores flowing away from the heads.
