Bonjour à tous, Je recherche cette publication :
This perithecium was found on Rabbit (Oryctolagus cuniculus) dung in 2011, which I named as Sordaria macrospora.
Ascus and spore data: Asci 220-243 x 30-35µm; Spores 35-38 x 17.5-19µm.
The first two (poor) images are of this collection.
This week, I found a similar looking perithecium with images showing better clarity of the setae which are long and sub-clavate. Unfortunately, it was immature so no spore data. Also on Oryctolagus cuniculus dung and from the same site.
The fungus measured 400µm tall x 300µm wide. Hairs are 75-200µm long.
I believe these two fungi are the same species and doubt my original identification which was made with little knowledge and less literature.
It's quite distinct in both colour and setae but I can't place it. Does anyone recognise it?
Regards, Chris
do you have any shots of mature spores ejected from the asci - thus showing nature of appendages etc.? Presumably not from the first collection (which clearly shows a pedicel in one of the immature spores at the bottom of the image). You may well have to wait for spores to mature in the later collection.
regards
Chris
Sure it lacks details for spores. If the presence of a pedicel confirms he's not a Sordaria; have you observed paraphyses, there is t he apical apparatus atop asci? Can you do other pictures immature spores?
Michel.
Lack of spore detail was always going to be an issue but I haven't any more images from the 2011 find and only one immature perithecium this time. I'm checking daily an will report back if I find anymore.
Thanks for looking, Chris
I think this should be Anopodium ampullaceum Lundq.
Typically are the transparent to light-coloured perithecia and the light brown hairs with swollen hyaline tips.
The spore size also fits very well and I mean to see some of the hyaline upper cells (pedicel) at your second photo.
Regards, Norbert
As I mentioned earlier I had spotted that pedicel, but was confused in that it appeared to be pointing towards the ascus apex - now I know why!
I see that virtually all the previous UK records have Mike Richardson as recorder or determiner. This might be why it appears to be restricted to Scotland https://data.nbn.org.uk/Taxa/BMSSYS0000001485 although Mike did a lot of work in Yorkshire and other parts of England and Wales as well. Maybe it is truly northern (arctic-alpine) in its distribution here. It also appears to be mostly restricted to lagomorph dung.
The attached may help those unfamiliar with this taxon - I know I was . . .

It looked distinct enough to think it might me easy, but alas ....
I hope this gets posted this time. We are in the centre of a huge Atlantic depression and the power keeps going off.
Best wishes, Chris
Michel.
I have only two gartherings from Germany, both on dung of hare.
Last I found it in 2001!
I'll attach the plate from "Lundqvist, 1964". A. ampullaceum (syn. A epile).
