I found on cow feces. It will be a Peziza??Thanks
I have Collected a Diatrypaceae on hardwood.
Here are some features:
Perithecia immersed, usually separated, spherical / ovoid with a diameter of 600-900um.
Ostioles emerging separately. With a round shape the diameter is about 350um.
Asci octosporadas on a long pedicel clearly IKI +
Are not mature perithecia and spores are difficult to obtain, however, the size of which are measured are on average 17.7x4.2um, and are slightly allantois.
With these data, I think it might be Cryptosphaeria and within this genre fits better with C.subcutanea.
You can give me your opinion?
Thank you very much, greetings
Susana
again an interesting find. I agree it resembles Cryptosphaeria by many traits but in this genus the wood surface beneath the stromata is typically strongly blackened unlike what shows your photo 2.
I suggest you observe a stroma in vertical section and compare it to Rappaz' description.
Moreover, C. subcutanea which might fit as to ascospore dimensions differs in having inamyloid asci and a fairly boreal distribution on Salix.
Try to find mature ascospores to check whether they become pigmented or stay hyaline.
Good luck!
Jacques
I found mature perithecia, and spores are pigmented, they are brown.
I made cross sections, and I noticed that the perithecia are grouped two to three and their necks are emerging together.
There is a black dorsal line (Fig.2) and in some cases a ventral black line also appears (Figure 3).
Now I think it may be Eutypella dissepta. It can be?
Saludos
Susana
