Enterographa crassa is a woodland lichen that forms extensive patches on tree trunks. I think it looks better wet than dry.

Also this arthonioid species which I think is Reichlingia anombrophila. Appearance and spores look right.

A few lichen things from a damp wander round the old trees in Felbrigg Park today. Coniocarpon cinnabarinum, Pyrrhospora quernea, Diarthonis spadicea and Cresponea premnea. The Diarthonis looks much better wet than it does dry!

Just for your amusement. Spores of lichen Amandinea punctata from a stone wall, fungus Hysterium angustatum from a sycamore trunk, and sickle-shaped conidia of script lichen Opegrapha vulgata from oak bark. Such features are important in identifying these inconspicuous gems.

More harvestman line drawings completed. Leiobunum species have such long legs that I didn't even try and fit them on the page.

Under some damp bark of a fallen poplar was this Hololepta plana, a curiously vertically challenged beetle.

Something instinctively told me that beavers were in the area. My mammal field skills were not tested.

reading about organisms that aren’t your specialty is like
margins of the quorbus eplungulate, ploobular processes bent posteriorly towards the foobulum
define term “eplungulate”
- lacking plungae. synonym: thubulous

That’s a good idea! Not sure my DIY skills are all that, but I might have an existing implement I can adapt for the purpose.

A couple of alula feathers from a dead woodcock I found. I don’t know who discovered it, but they make excellent brushes for manipulating insect scales when dissecting. I am planning to mount one on a small wooden handle. Might be good for cleaning lichen specimens too.

I think Cladonia can show the colour all year round, but is more obvious in winter months when it is well hydrated.

Cladonia diversa is very variable, with some podetia bearing swollen bright red fruiting bodies, and others just tiny red studs on the cup rim. Heaths and dunes.

A grey form of Evernia prunastri seen today, which could be forma herinii, which is deficient in usnic acid. Growing alongside the normal greenish version.

The poster for this NNNS event has been changed today (28/01/26) to clarify that whilst everyone is welcome to attend this event, it is free for NNNS members but there is a small charge for non-members (£3/£2 for students). Apologies for the confusion.

Some tideline pebbles on the sheltered (saltmarsh) shore of the dunes at Burnham Overy had lichens on them. This one turned out to be Lecanora helicopis, which was previously recorded at the same site in 1989, only 37 years ago.

While visiting the local museum I noticed that herbarium specimens lose their colour after a while - do you know if they retain spot and UV reaction capability? There are quite a few boxes of unidentified specimens…
