White mould on fallen and decaying Eucalyptus woody fruit
Stephen Mifsud, 19-11-2019 06:16
Stephen MifsudI 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.

Re : White mould on fallen and decaying Eucalyptus woody fruit
Hello Stephan, you should look in Clonostachys spp

what you call Verticilium it is young conidiophore of clonostachys

Best wishes

Re : White mould on fallen and decaying Eucalyptus woody fruit
Thank you so much Angel Pintos - You are right. Interesting microfungus with two different morphological states (Verticillate then Penicillate!)
