Todays post is another small fungus, this one is only 1/2" 12mm across the widest and was growing on a dead twig of Blackberry Rubus fruiticosus laying in the bottom of an old field hedge. This veiw is from the underside showing the gills. the top side is smooth and white and seems to curl under the bottom edge as you can see in the image here.
A tentatife ident on it puts it in the crepidotus with 3 possibles, C.applanatus which what I have it labled on the hard drive, Mainly because of the colour and the smoth white appearance of the top, another is C. variabilis which seems to prefer this type of plant material to grow on, the only this I have against it is that all the images I have sem to show both a more iregular edge to the cap and also the cap seeming to face up-wards, the 3rd is C. epibryus,which the images for look very simular. All 3 species say late summer to autumn, but it has been a very mild winter here in Nottinghamshire and they were in a very sheltered spot in the bottom of the hedge.
Hope some body can comfirm or change my mind about these ID.
Thanks for looking Yours Robert

These are a pain to ident. I have a lot of photos and differences are too subtle. Again mycroscopic help is needed.
Acording to my books, I would guess epibryus, if you ask me why, only because your photo looks very similar to one of my books :D
If I take into account the descriptions I would go crazy, there are no definitive keys.
Nice to see some fungi from you, Robert.

Hi Robert,
Looks like the old Sony performed flawlessly here. Exposure looks great. Nice subtle colors in this soft light. Outstanding detail and texture shown here. Guess you won't nedd that D200 after all.

Hello Rob, I think you are correct on the ident, I think it is hard to get to a species level. Nice composition, and interesting specimen. I think it could do with a little more contrast. Well done.

Without microscopic analysis you can't say anything 100% sure in this genus, but another option is Crepidotus cesatii (Rabenh.) Sacc., a species very common in late autumn / winter, and frequent in Ireland as I observed. C. variabilis is more or less a summer species, C. applanatus mostly grows on conifers and is bigger in size - C. epibryus is a serious option, however, is mostly a summer/autumn species also. Meanwhile I always found this small Crepidotus from November to March in Ireland.

Have a nice festive season, and thanks for running TN. Kind regards from the Emerald Isle, László
