Dear Forum,On decorticated wood of Castanea,I foun
I found this pyreno growing on the wood of a decorticated tree. The advanced maturity make the perithecia look like apothecia. Here are some details of it in addition to the attached photos:
- Asci with indicative dimensions 73.2 - 87.1 x 7.6 - 9.9 µm;
- Spores hialine multiseptate, mostly 3-septate but there are some with more septa, with
(18.7) 20 - 28.7 (29.4) x (3.9) 4.1 - 5.4 (5.6) µm
Q = (4.1) 4.3 - 5.8 (6.2) ; N = 20; Me = 23.2 x 4.7 µm ; Qe = 5;
- All parts I-.
Thanks in advance for any hint about its classification,
zaca
Thanks for your response and for the hint about the genus, that is new to me. Meanwhile I saw some images in the internet and the sections (as well as the spores) of some species are indeed very similar, except for the inexistence of spines in this case.
As requested I will send you a part of the specimen, which broke into pieces (because the wood was degradating).
Thanks again,
zaca
