Bonjour, Marie-Rose D'Angelo (Société Mycologiq
This was growing on Rabbit dung. Hyaline to white 0.3 - 0.45 across. The spores were on average 13 x 8 with a large guttule in one end (in Meltzers). The asci were 55-80 long. The paraphyses slightly swollen at the ends.This keyed out to Coprotus disculus.
Is this a possiblity?
Thanks

IL is sometimes difficult to separate certain species of Coprotus. C.disculus generally has more cylindrical asci, but it can also have more clavé asci and spores biseriate as part of your photo. It often takes several copies observe to get a better idea. If you happen to watch the top paraphyses you may be also notice if they are slightly uncinate.
Michel.
in my opinion is this Coprotus leucopocillum. How Michel says are the asci from C. disculus more cylindrical and the spores uniseriat, the paraphyses more uncinat. The microfotos are rather old.
Greetings Peter.
Thanks for your thoughts. With a bit more study I have found some more cylindrical asci but most are much more clavate. The more mature asci are also longer with 95µ being the norm.
Some of the paraphyses are straight and some slightly bent but I don't think I would call them uncinate.
The spores are still slightly small for C leucopocillum at 13.5-13.7 but I think that is the most likely identification.

Ps the final photo should the length of the ascus be measured to the septa where the base starts or to include the base?
Michel.
Thanks Michel.
