I've found these in both my outdoor and indoor collections, but mostly indoor. There is this invasion of black, slimy what I can only guess is mold on top of my sphagnum dressing. Closer inspection shows that it's made of very very tiny spherical clusters that resembles very fine caviar. When I dab some on my fingers and rub them, it smells sickenly sweet. Are these harmful and what can I do to get rid of it?
Thanks a lot.
