You could place part of the mould into a cut in a piece of citrus fruit to continue its growth. Citrus can also host P. italicum, the below website is one mentioning how to differentiate between them.
Aspergillosis: (fungal spores growing in the lungs) which is uncommon.
Asthma: penicillium spores have been associated with increased chance of onset of asthma, and problems with breathing in people with asthma.
There may be other hazards.
I just cite one paper below, but a search using terms of penicillium and asthma shows lots more.
"Household airborne Penicillium associated with peak expiratory flow variability in asthmatic children"
