Hi , I found an interesting Penicillium s.l. (could be Talaromyces) that was growing on a very specific substrate. Inside my cupboard was an old cartoon of red wine that, tilted and it was slightly leaking. A dull green mould was growing on the wine-soaked cartoon box. I managed to culture a pure colony on PDA, MEA, and CZ
On CZ and MEA it released a very deep red pigment - so amazing!! On PDA no pigment was released.
I wonder if one can help me with the identification (or suggest some literature to consult)
I have not yet examined the material under the microscope as first I wish to have a pure colony to save for the future. The slow-growing mould (at room temp of 29C!) is dull green at the centre, then fading and changes to a cream border and white margin. There are a few options but not sure what it is yet.
