Parasiter på mossor finns det rätt många av. Oftast är det svampar. Här Arrhenia retiruga som växer på en skuggstjärnmossa

Moss Navel, Arrhenia rickenii.

Eaton Park, Norwich, today.

Moss Navel, Arrhenia rickenii. A single fruitbody, growing in moss on a wall. Moss Navel is saprophytic, nearly always on mosses on alkaline soil - in dune slacks or on unimproved grassland overlying calcareous rocks or on the moss-covered lime-rich walls.

An interesting feature about this fungus and a few (but not all) Arrhenia is the lack of gills which is quite unusual for a basidiomycete fungus (the group containing most fungi you and I call 'mushrooms'). 🍄

🍄‍🟫 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.

I was going for genera in Hygrophoraceae; Hygrophoris, Hygrocybe, etc. Even worked some Arrhenia in at the bottom. Thankfully, my illustrations no longer need be accurate. 😁

A fungus photo a day: The brown goblet/Arrhenia epichysium is not rare but for some reason yesterday is only the second time I’ve found it. #fungifriends #fungi #mycology #naturephotography

Arrhenia "sp-CAO4"
An undescribed blue-green Arrhenia that can be seen in chaparral habitats in California. Known so far from 2 sequenced collections by Stu and myself.It spans from LA to the Bay and likely further.
Saw on a late starting New Year's Day hike in the Oakland Hills. #mushrooms

Back in the graveyard before Christmas, another mini-mushroom, Moss Navel (Arrhenia rickenii), hiding amongst the moss on a tombstone. If you don't seek, you don't find. #fungifriends #fungi #mycology

Interesting-looking fungus growing from moss atop a tombstone in Doddington churchyard. I took it for dead leaf at first. ObsIdentify says it's Arrhenia spathulata. #KentNature #fungus #fungi @caringforgodsacre.bsky.social
A pale brown, lobed, flattened fungal body, resembling a dead leaf. It is growing from the edge of a patch of moss. The same fungus, from a greater distance, showing the fungus and moss is on the top of a lichen-encrusted tombstone. In the background is a church porch.

Arrhenia retiruga I think, quite common but how many people spot it? It can be found even in built-up areas on moss-covered walls. Funnily it got locally redlisted as probably regionally extinct in Czechia in 2006, I think it got found even before the finished red list got published.

Based on that I’d suggest Arrhenia- I’ve seen Arrhenia rickenii on mossy walls around Norwich.

Old mossy lawns around University of Liverpool’s city campus yielded some interesting #fungi. Particularly the black cups next to old tree stumps. Any help with ID would be very welcome #fungifriday
