Hi to everybodyI need your help with this fungus that forms superficial black, lageniform, ostiolate perithecia, up to 0.45 mm high, 0.2 mm broad with necks 0.1 mm in diameter, singly or clustered in groups of several perithecia covered by a copious whitish or greenish blue, aerugineous subiculum. Non stromatic or very inconspicually stromatic.
The irregulary disposed clusters covering several cm on rotten wood of Alnus glutinosa at the Botanical garden of Gijón, at the north of Spain at the sea level.
The narrowly clavate asci, 8-spored but four of them aborted, 44-58 x 4-5 microns, have an strongly refringent apical apparatus not really Melzer positive. The ascospores are hyaline, smooth, biguttulate, one-celled, 4.9-5.8 x 2.6-3.1.
I don not have any good track, but perhaps you could help me?
Thanks in advance
nice find! I would suggest to dig into Boliniales but I have no genus to propose.
Amplistroma might be considered too but it has consistently globose ascospores.
Can you check the presence of a germ pore on ascospores? They are minute and hyaline, it might be challenging.
Good luck,
Jacques
Hi Jacques
With the kind permission of Jesús Linde, allways the collector, I could send you a part of this collection together with A. michelianum. Do you like it?
Thanks a lot, as allways!
PD. I couldn't see any germ pore at the ascospores
