I answered this in another forum topic, same answer:
We used to have tiny brown spots all over the inside of our barn, especially on light fixtures. For years I assumed these were deposited by insects. Turns out it is usually artillery fungus from wood shavings, mulch etc. Lots of pictures and articles on the internet if you search this term. Some examples from Penn State and Cornell:

So far, I haven't seen a good cleaning solution, but maybe you should reconsider the mulch next to the house? |
