I was up in Wensleydale today, so called in at a @yorkswildlife.bsky.social nature reserve I've not been to before, Leyburn Old Glebe.
It's best known for its flowers, but actually had a few waxcaps today. Enough to encourage someone to go back next year (I'm not close enough).

I found this enormous Pike this afternoon, looks like it may have been eaten by an Otter. I'm not sure anything else can taken in a 4'6" long Pike and would eat the insides. It didn't smell much so was fairly fresh.
Anyone seen anything to suggest something different? @sorbynathissoc.bsky.social

I put out a moth trap more in hope than expectation last night. So only one macro, a Red-green Carpet, was ok with me.
Today I found some Yellow-flowered Strawberry spreading about in a churchyard at Dronfield. New for me.
Wildlife is endlessly interesting. Always something new or surprising.

A few fungi from a walk at Ladies Spring Wood, Sheffield today.
Wrinkled Peach, Common Funnel, Wood Blewit and Honey Fungus.
Honey Fungus seems to be taking advantage of of stressed trees from the summer drought, as it's common this autumn.

Well when Lancashire gives us bits of 'east Lancashire' and back I'll speak to my countrymen in Mid Yorkshire Fungi Group about their boundaries. 😜
Although I've been well indoctrinated to call my patch, Sorbyshire. A new county, I have divided loyalties (Yorkshire/Sorbyshire) now.

Possibly a new (to me) pinkgill, Entoloma violaceoserrulatum, found in my local cemetery. But pinkgills are tricky, and impossible to be sure without microscopy.
The photo doesn't do the indigo colour of the stem justice.

Grassland fungi are not as showy as usual this year. I had to do a lot of searching to find not many species today. A bit more rain should bring more out hopefully.
Meadow Coral, an undetermined Earth-tongue (finger for scale, this is a big one), Blackening Waxcap.

Has anyone else noticed bladderwort appearing where pre planted coir mats or rolls have been used? I can't be certain that's the source, but noticed this twice now.
(Not sure which species this one is. But the other was U australis).

Rove beetles are the odd beetles that don't look like beetles. Their wing cases being short and their abdomen is on show, unlike other beetles.
This large beast is a Devil's Coach Horse, and is a predator of other invertebrates.

I was in the centre of Rotherham this morning for a meeting, right by the river. So I had a look for any interesting plants.
Plenty of Frogbit, which is otherwise rare in South Yorkshire, and declined enormously. It must be floating down from somewhere upstream.

Not so many things still in flower now, but a couple of things from this week. Nodding Thistle, and Autumn Gentian. From a couple of @yorkswildlife.bsky.social nature reserves on magnesian limestone (Brockadale and Sprotbrough flash).

I found a small one still in flower this week. Although in a heavily grazed field, so probably just trying to pop up between nibbles from the horses.

As long as you go in July or August I like to sample the fruits. Bilberry is purple inside, Bog Bilberry is white (as here). I think I'd have to see the two near one another like in your photo otherwise.
But eating a few berries is much tastier.

Great Mullein from earlier in the week at Lathkill Dale in the Peak District. Most had finished flowering, but found one or two still in flower. Rosettes will flower next year.
The hairiness of the filaments being a key thing to look for in this species.

Ash dieback is continuing to take a toll on some of the nature reserves I look after. @yorkswildlife.bsky.social
Some very large ash died this year, some looking ropey. Many small trees already dead. Lots of trees to make safe near paths and roads.

I went investigating on scree habitat today. Looking fairly bare, it mostly has commoner plants. Wood Sage is frequently in bare scree, Mouse-eared Hawk-weed often where soil is starting to form.
The thing I was looking for though is very rare, Red Hemp-nettle. Declined in arable, but still ok here

I went for an autumn wander today, still a few things in flower, although mostly IDing things vegetatively.
Harebells still going strong, Dark Red Helleborine not in flower but easy enough to find at the moment, I tried IDing an eyebright, it was just the common one.

Choosing a favourite for #WildflowerHour is impossible. So just a couple of things that I was pleased to find in 2025.
Rare Spring Sedge involved lots of crawling around on my knees looking at small sedges
You can't find Grass Vetchling if you want to, I just happen across it every couple of years

I rowed out to some of the islands at Parson's Carr nature reserve today. In spring these are home to many Black-headed Gulls, which prefer no trees and less vegetation, so was brushcutting, Sophie was chainsawing
Spear-leaved Orache was very common around the shore line

Last of the Parsley Water-dropwort flowers. Only plants regrowing after browsing are now flowering, the rest are running to seed.
I rubbed a few plants today, and they do indeed smell like parsley or parsnips, but so many carrot family things do, maybe there is another reason for the name?

Sometimes bees key out easily, other times not. This male furrow bee was tricky, although I had a good idea what it was I struggled to get through the key to the right place. Discounting all the other species I came back to Orange-legged Furrow Bee (H. rubicundus)

An early start this morning, our ponies needed a visit from the vet, who wanted to come at 9am. We needed to set up our temporary squeeze in the catching pen, and allow plenty of time for these fairly feral horses to not follow the script. But they did as was asked, in the pen first time.

I went to go find one of only 2 locations in South Yorkshire today. A golf course! I had to wait until after hours to avoid being hit by balls.
It's seems happy enough in the current management of the rough areas.
