A few green croziers starting to push through in a brown crown of scales and old frond stipes.

Lovely.

And Ophioglossum azoricum. 🌱

😂 Orangy one looks like Rhizocarpon oederi, not sure about the pale one in the middle, looks almost lichenicolous.
Nice Stereocaulons. Guessing a metal rich rock.

Nice sized clumps 💚

Worth contacting the archivist and explain your making a special trip, and ask if it is possible to see material not on display.

It's definitely worth a visit. It has his measured drawings and paintings; life size work drawn from the birds brought in by locals. Very different to his engravings and commercial work and absolutely breathtaking. Every time I visit I get lost in the detail.

A great #FernFriday today. Spent the day at the World Museum in Liverpool identifying our filmy ferns from #Honduras. #BritishPteridologicalSociety #EdgeHillUniversity

Two types of fern growing next to each other.

Hello #FernFriday

Beautiful 🥰

Least Adder's-tongue on the patch last month. Only grows in a small 2m square of turf on Guernsey. I didn't know exactly where this was before a passing botanist pointed me in the right direction. At about 2cm tall, no wonder I hadn't noticed them before.

Fantastic, I wonder where they are all heading?

Wow, looks like it's possibly a lichenicolous lichen. Nice spot. @britishlichensociety.org.uk

More likely to be an early hopeful male. Females tend to be swamped the moment they arrive.

Fantastic 🥰

Maidenhair Fern Adiantum capillus -veneris at its well-known site in Bath, curtaining one end of a canal tunnel, but now spreading to the outside wall at the other end and even to the wall of a nearby railway cutting. #FernFriday #FridayFerns #ahashtagwithFernsinit

Well it's a cold and wet #FernFriday, so time to sit down with some new books and explore distant lands... #Michigan #NewZealand #lycophytes

Walking through nature and discovering a place like this is fantastic.🌿🌿

I've registered for this webinar "Taxonomy: What is it good for?" by @sandyknapp.bsky.social, the story of the mega-genus #Solanum. (Note that 12pm ET = 5pm (17:00h) GMT)
Here's a rather mini member of that mega-genus. 😉

Dark green once pinnate fronds against a dark grey wall with snow on top of the ferns.

Rustyback's (Asplenium ceterach) seem to be loving this snow!

Really enjoyed your talk, thank you.

I think it should survive, but I don't know for sure. It would be interesting to know how it fares.

One of the most beautiful things I have seen for some time. Frosted Hymenophyllum tunbrigense. Never seen this patch with frost before @sussexwildlife.bsky.social Eridge Rocks nr. Tunbridge Wells; named after this tiny disjunct population; more common in UK Atlantic woodland @bsbibotany.bsky.social

Great idea.

In the UK we have a Small Claims Court for low value redress; but yes, you could hand it over to a Debt Collection company if they don't settle within a reasonable time frame.

New site record of Hymenophyllum tunbrigense for Co. Louth (H31) growing in a rocky woodland on a minor hill. Happy to find this one today. A very scarce species in the county.
