Edit: next one in the sequence added (Thursday). They matured very quickly and starting flinging spores everywhere.

There are some conidiophores of a dematiaceous hyphomycete (the tiny black "bristles") in this image - they could well be identifiable I suspect, if you wanted to post some images of the conidia, I'd have a go . . . .

Hi Chris

I've often wondered what the bristles were.. wood samples are often covered with them. I thought they may be remnants of smaller corticolous myxos.

If I can get something resembling spores from them, I will post them.

Cheers,

John

Hi,

I was fortunate to get hold of a supplement published by Bruce Ing, to his great book " The Myxomycetes of Britain and Ireland". In it he now calls this Trichia meylanii (Ing , nom. et sp. nov.) as there is strong evidence that it is a distinct species.
The name Trichia olivacea had already been used by Persoon and Whithering for another species so T. meylanii was chosen to commemorate Charles Meylan, a myxomycologist of the early 20th Century.

The FRDBI is up-to-date and has T. meylanii as the current name. For anyone interested, the identifying features are the circumscissile dehiscence (nicely shown in these photos) as opposed to the irregular "tear" in T. decipiens. Under oil immersion T. meylanii has minutely warted spores wheras T. decipiens has faintly reticulate spores.

Thanks for th update Dave, I noticed you were using T. meylanii on your website. Good to know - I don't have that supplement yet.

I didn't even need to go looking for this one - I noticed a small group of them growing behind a sample of Stemonitis I was investigating.

I seem to still be hogging the myxo section, but as long as nobody minds.. here's another.

Trichia affinis, found in Northumberland recently.

Which microscope and camera are you using for your micro images?

This camera https://micro-science.co.uk/product/mic ... th-usb3-0/

Although I think this camera is as good and uses the same excellent software https://micro-science.co.uk/product/mic ... lcmos-5mp/

Probably best if we open another thread somewhere if you would like to discuss further.

Cheers,

John

Stunning photos, well beyond the abilities of my mere 105 macro lens .... :lol:

I saw this today and had no idea what it was - a steer from Sterry and Hughes' Collins fungi Guide points me in the direction of a slime mould, some sort of Stemonitis fusca??? It was slightly more lilac-coloured than the photo shows.
