conidioma on a mouse dropping
François Bartholomeeusen, 08-03-2021 22:09
Dear forum members,

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

Nice picture of the synnemata.

This is a species of Peniciium, probably P. vulpinum.

Hi David,

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

Re : conidioma on a mouse dropping
Hi François,



Penicillium vulpinum is just a guess. Penicillium coprobium and P. coprophilum are related synnematous species in Series Robsamsonia that also occur on dung and might be what your collection is. You would probably have to study it in pure culture to be sure.

Re : conidioma on a mouse dropping
Good morning David,

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
