Hello.An anamorph located on the surface of a thin
On 26 February 2020, I found some conidioma on a mouse dropping (< 7 mm).
The colour changed day by day from white to bright yellow to greenish yellow.
I am not familiar with fungi in an anamorphic state.
Is this called a synnema? The conidia are globose/ovate and measure 3.4-4.2 x 2.4-3.2 µm.
I would like your help to identify them.
Thank you very much in advance,
François Bartholomeeusen
Thank you for your reply. I thought P. vulpinus was host-specific. I forgot to mention that the synnemata were smaller than 2 mm. Probably dung is dung!
Kind regards,
François
Thank you for your suggestion! I am sorry to say that I have neither the knowledge nor the equipment to set up a pure culture. I have tried reading Houbraken et al 2016 and taking into account "mouse dung" there are 5 candidates in the section Robsamsonia: P. coprophilum, P. coprobium, concentricum, P. glandicola and P. vulpinum.
A final microscopy attempt did not provide a clear picture of the synnemata's structure (attached some photos).
I classify this find as Penicillium spec.
Thanks again and best regards,
François
