Two summers ago, I switched to a new cube of genuine New Zealand … sphagnum moss.
That summer started to see this large green lichen like stuff. About the size of an American quarter This year, it is everwhere…even huge patches on the ground under benches. Note the little umbrella…
Deap dive into lichens, looks like a Peltegera species; but then, I’m an aspiring space cadet and not a lichenologest.

Was lifting the whole mass out and discarding. Luckily, Roundup ‘painted’ directly on kills it. More invasive than Scotch moss.
Note the overly aggressive moss around it… probably sphagnum moss. Grows ~3" in a summer and takes over a pot. NOT the tight short green moss I like…
Blame it on the Bosanova…
Bonsai On!
