🍄‍🟫 Another parasitic fungus that frequents mossy walls (photos from back in December):

I've identified this one as Arrhenia retiruga, with the common name Small Moss Oysterling according to #iNaturalist. Seems to like the common cushion moss #Grimmia as a host which it parasites upon.

Spotte vandaag een prachtig kussentje van Grimmia pulvinata op een oude muur — zo'n klein wonder van de natuur dat je bijna voorbijloopt. #mos #urbannature #grimmia #biodiversiteit

Fuzzy moss growing on concrete. Super cute.

Saw some cool moss today. And now you can, too!

I am pretty sure it is Grimmia pulvinata. So fluffy!

Any bryophyte lovers out there please feel free to correct my ID. 😊

A cute 🤗 bryophilous pezizale: likely #Octospora musci-muralis on #Grimmia pulvinata (Les Clayes-sous-Bois, FR).
