Lots of moulds on this table, which has been in the weather for many years. I am unclear about what features (beyond colour), differentiate one mould from another. So these few ‘mould sightings’ (4647245, 4647246, 4647264, 4647449 & 4647452), could include duplications, or be totally different. I’m looking to learn!
For this faintly white & thin mould, the 2nd photo is to provide context. The 1st photo is the only reasonable close-up. Both were taken when it had been hot & dry for at least a week.
