An excellent example of the necrosis it can cause on epiphytic bryophytes. Thanks for the tag.

NNNS Transactions article 2 details aphid recording carried out in the Norwich area between 2020-2025, during which time @norwichbirder.bsky.social managed to locate & identify 144 species. Around 1/3 are illustrated, including some excellent photographs from @caryocatactes.bsky.social 3/x

Do I need this Sarah? I think, perhaps, I do! Congratulations.

This looks like fun, as well as being hugely worthwhile. How can people sign up as a volunteer?

Lots of Claviceps spartinae on the Spartina in the Southport saltmarsh today. On a few plants the Claviceps was hosting Fusarium heterosporum too!

Do microbes get more food by swimming or staying still? Turns out both work, and cilia help them pull in nutrients no matter the strategy. buff.ly/vK3GmK5

A great explanation on how to define a species. It’s complicated… www.scienceofbirds.com/blog/how-do-...

I had the honour of reading this pre-publication. It seems even better second time around! If you live in the south-east of the UK, you won't find many of the species covered but the book is still worth buying. The advice on HOW to look and how to attempt IDs is second to none.

Is this the year when you're going to get to grips with identifying grasses? They can be tricky, especially when growing in "interesting" ways, like the Creeping soft-grass spotted by @averisben.bsky.social. Don't worry, we have some great #WildFlowerID resources for you: bsbi.org/learn/resour...

Did somebody mention basal rosettes? Check out the fabulous Basal Project website, it has almost 2,000 photos of basal & juvenile leaves of British & Irish wild plants: basalproject.org.uk

In this review in Fungal Ecology, Håvard Kauserud (@drhyfe.bsky.social) argues that while the ITS region is by far the best DNA (meta)barcoding marker for fungi, we should not use it naively or simplistically doi.org/10.1016/j.fu...

There are five species of aphid that feed on Bamboo in the UK - so far I've only managed to find this one, Takecallis arundicolens, found again this morning from Bamboo overhanging a pavement in west Norwich.

Vegetative identification of ‘small’ Geranium species can be tricky and you need to take a close look at hair length and glands as well as degree of lobe incision. Here are a couple of useful resources archive.bsbi.org.uk/BSBINews99.pdf pg 22-28 thewildflowersociety.org.uk/wp-content/u...

An hour to kill? Is it possible that the fabulous @trevorthebotanist.bsky.social doesn't know that his #UrbanPlants talks are #AppointmentViewing, just like #TheTraitors? Such modesty!

It is John Aubrey’s 400th anniversary this year! My next book publishes his Natural History in full for the 1st time. It is not the quaint collection of random anecdotes suggested by the heavily edited 1847 version, but cutting edge c17 science all penned with Aubrey’s characteristic brilliance.

Sunday book review: Pan-species Listing by @graemelyons.bsky.social Publisher: @pelagic.bsky.social Review: markavery.info/2026/01/04/s... "Hardly anyone has the knowledge to write this book & even fewer could write it so well!"

There are two other lichen guides for Britain and Ireland in print. But this is the first one written by a northern team. If you live in the North of the UK, then this is definitely the one for you.

Looking good. Great to see lichens included.

Interested in moth trapping? Wondering which trap to use? Or if different bulbs collect different species? Using 100k samples from @gardenmothscheme.bsky.social our new paper looks at these questions and more! With with Bill Kunin and @katatrepsis.bsky.social #mothsmatter #teammoth

On Sunday February 22nd I'm doing a lichen walk and talk at Higham Hall near Cockermouth. More info here: highamhall.com/course/liche...

Which theme will your best pictures fit into? Don't forget to give your photos titles to get people's attention. You'll want to win as many votes as possible!

The theme for this meeting is Lichens in Churchyards and on Man-made structures. Come and hear how lichens can form a protective layer over stone.

Such a perfect posy.

Gulnara Tagirdzhanova nous a présenté ses recherches sur les interactions au sein des lichens à partir d’approches omics.

An amazing photograph! Will we receive work of this calibre for the British Lichen Society photo competition? Details at britishlichensociety.org.uk/the-society/...

What an amazing resource this will be!

Some fungi are so small they are only likely to be found by deliberate searching. This curiosity was shown to me today at Whitlingham. The 'large' structure here is an old nail gall on a lime tree leaf caused by Eriophyes tiliae. The fungus, Ophiognomonia melanostyla, is the tiny black prongs on it!

I’ve seen quite a few of these tiny Mycena pseudocorticolas recently, always amongst moss on damp tree trunks. I like em.

Had a lovely time chatting to Ellie, The Curious Geographer, about stone lichens and how they challenge our thinking about the natural world and our cultural heritage @britishlichensociety.org.uk @oxfordgeography.bsky.social youtu.be/9tO_5yBvQmw

Small coffee-bean shaped fungi on bark. There are a few species, but this is probably the commonest - Hysterium angustatum, distinguished by the 4 celled spores with rounded ends. Foxley Wood.

These are amazing! So creative and unique.

Fabulous. I'd love to see more of these as you work through your data. What part of the country were you in? I'm not seeing some of those pathogens. I probably just need to look harder!

Key findings: • 42% loss of rough grassland, heath and wetland since 1930 • Pastures and meadows reduced by 29% • Arable land up by one third by 1990 • Urban areas rose from 13% to 20% A fresh perspective on how our landscapes changed over 90 years www.ceh.ac.uk/press/maps-c... 3/ #LandUse

This is the first British & Irish lichen book, that I am aware of, which is not focused on species common in southern England. Definitely the best beginners' lichen book to buy if you live in the north. That's one benefit of Scottish authors!

A great book. Enjoy.

Mother: Excellent. Can you do me another? Me: Thanks Mum. What were you thinking? Mother: Holly and ivy with snowman. Me:

#naturewriting I’ve now read Trevor Dine’s Urban plants twice and keep dipping in. It’s one of the most compelling, captivating, well researched books I’ve read in years. To combine scholarship with such engaging prose and a brilliant choice of images is the work of a writer of real distinction.

You have at least six well photographed species here. Bring your photos to the next #AquaticHyphomycete online session and we can help you. Meanwhile look up Clavariopsis aquatica and Tetracladium marchalianum to start with.

Gorgeous. The best photo of a lichen community that I've seen for ages.

You've missed my birthday list this year too. But I'm happy to take a voucher for a pre-order for Christmas! I'll let my family know. We'll done @sarahwhild.bsky.social
