🥳We are very excited to see work starting on one of our biggest ever wetland restoration sites. Now, after lots of planning and preparation, the diggers have arrived to turn an area almost the size of Hyde Park into a thriving wetland. Read more here www.wildlifebcn.org/news/work-st...

Interesting fungal find: This parasitic plant fungus (Exobasidium karstenii) lives exclusively on bog-rosemary (Andromeda polifolia) and makes some of the leaves much broader, and purple. The green and the purple leaves here are the same plant! #naturephotography #fungifriends

My goodness, that looks like a nice bit of lowland spring fen. What was the moss? Thatchy & tall dead reed means it could do with a good cut & collect, then goodness knows what good things may return, perhaps grazing later on happens? Sweep netting in May & June needed for soldierflies...

Brian Eversham @brianecambs.bsky.social · 19/09/2026
Nothing special so far, but thick stands of Calliergonella with some nice amoebae etc. looked promising. Yes, the fen and the meadow both need more management; I don't think the wet parts have been mown or grazed for a few years. I hope a local grazier might put a few cattle on once it's re-fenced.

A species can be common in an ecosystem and still be doomed. If it can no longer reproduce, e.g. due to degradation or climate change, it's likely already facing extinctioning. Sometimes ecosystems reflect land-use decisions from 50y ago as much as today's. New piece on ghosts, debts, and credits.

Wonderful ancient artistry! About 40,000 years ago, this small, graceful horse figurine was carved from mammoth ivory! Imagine the #IceAge artist at work, sitting by the warmth of a fire, creating what is the world’s oldest known figure of a horse! 📷 by me #FindsFriday #Archaeology
My photo shows a profile view of a small horse figurine with head to the left, displayed against a dark background. Sculpted from mammoth ivory, the surface is a mottled greyish-earthy-brown colour with a shiny patina. It was once likely off-white in colour. The head is gracefully lowered with a long and elegant curving neck, and a convex curved back. The four legs are incomplete. The top of the tail remains. The eyes, nostrils, and mouth are carved as indents. It measures a mere 2.5 cm in height, 4.8 cm width, and 0.7 cm depth. 

The 'Vogelherd Horse' was excavated in 1931, together with a number of other ivory animal figurines from the Vogelherd Cave, Swabian Jura, Germany. It is the oldest known sculpture of a horse. On display at the Museum of Ancient Cultures, at Hohentübingen Castle, Tübingen, Germany.

Deacon in local Catholic Church went full Ezekiel in homily today, re climate crisis and the horrors being visited on those least responsible: "seen recently in Nepal and Tibet. The blood of more than 1,300 people is on our hands, from this one incident of climate injustice alone."
Deacon Ray's Homily 23rd Sunday in Ordinary Time 

"It is important we celebrate this feast appropriately because part of our duty, as the body of Christ, is to be responsible stewards of creation, another most precious gift which God has granted us. We have lived comfortably using the resources of the Earth, without regard for future generations, but the debt is now due, and we need to make difficult choice about the way in which we live. This is especially true in the western world where despite baking summers and sodden winters we are still largely sheltered from the worst effects of the climate crisis, while those in less wealthy countries suffer disproportionately, as we have seen recently in Nepal and Tibet. The blood of more than 1,300 people is on our hands, from this one incident of climate injustice alone. 

To borrow a famous phrase from a fictional journalist, the job of the homilist is "to comfort the afflicted, and to afflict the comfortable". So, if you are still sitting comfortably in your pew, then I have failed this morning. But I hope and pray that you are feeling just a little uncomfortable, and that your hearts have been softened towards your brothers and sisters, whoever and wherever they may be."

A new book on British Earthstars by Jonathan Revett is now available to preorder from @summerfieldbooks.com #MycoBookClub #fungi #FungiFriday #Mycology www.summerfieldbooks.com/product/brit...
British Earthstars by Jonathan Revett14. Geastrum rufescens Pers.

Rosy Earthstar

<<< rufescens = red, reddening >>>

Icons: Pegler et al. (1995) p103; Jeppson (2013) p168; Læssøe et al. (2019) p1249.

A medium to large sized species with thick fleshed pinkish-red non-hygroscopic rays, a fimbriate peristome and stalked spore sac

Unexpanded fruitbody: Subglobose, 30mm 40mm.

Expanded fruitbody: 50mm - 90mm with 5-8 non-hygroscopic rays, flattened or arching with age.

Mycelial layer: Persistent, encrusting debris.

Fibrous layer: Pale grey brown

Fleshy layer: Warm reddish pink, flesh up to 8mm thick when fresh, quickly cracking and falling apart, darker with age but normally with residual reddish tones.

Spore sac: Subglobose 10mm 30mm diameter, greyish buff or light brown, smooth or minutely hairy (hand lens needed!) and with a fimbriate peristome which is often ill-defined and a short stem.

Mature Spore Mass: Dark brown.

Spores: Globose, 3.8µm 4.3µm, covered in elongated warts up to 0.5µm high.

Capillitial hyphae: 4.0µm 8.0µm, thick walled, tapering, encrusted.

Habitat: Rich litter in both deciduous and coniferous woodland, parks, arboretums.

Distribution: An uncommon species but well represented across Britain.

Discussion:

Unmistakable when fresh, thick fleshed with some degree (often very intense) of pinkish red tones and a weakly defined fimbriate peristome. The spore sac often degrades very quickly, especially around the peristome and can end up with several tears and holes. The short stem is best seen in mature specimens when all the flesh has eroded.

Unlikely to be confused with other earthstars when fresh but old specimens can resemble Geastrum michelianum or even Geastrum fimbriatum however the rays normally have dark reddish tones and sometimes dried patches of the thick flesh. The spores are also larger than G fimbriatum & G michelianum.

Often found in and around rotting tree stumps or on big thick piles of needle litter.

European Distribution & Species:

My reading of it is that the whole Dyke is in Cambridgeshire vice-county, which many recorders still use; and the north-east side of the Racecourse section is in modern administrative Suffolk (whose boundary follows the Dyke), so if you use modern counties, the butterflies there probably visit both!
