[Nhcoll-l] Mold curiosity

[Gali Beiner]

Dear All,

I noticed this little popular press article on mold that thrives in RH ca.
55%:

Denmark’s museum objects at risk from ‘extreme’ new mould, say conservators
| Denmark | The Guardian
<https://www.theguardian.com/world/2025/may/06/denmarks-museum-objects-at-risk-from-extreme-new-mould-say-conservators>

Has anyone noticed this happening in natural history collections? There
are, of course, many types of mold - we dealt with some in our bird
collections - but generally lowering the RH (to taxidermy-appropriate
levels) appears to help. However, it would be good to know what other
professionals see in "their" collections in terms of molds working in
lowered RH conditions.
