Hi all,
A few weeks back a friend pointed out some yellow fuzz in small cavities in stems of Aralia (A. elata or A. spinosa). I saw some depauperate perithecia among the fuzz. So I put the stem in a moist chamber for a couple of weeks.
A pyrenomycete has since grown. There are some small necks, fully covered in the same yellow subiculum. The subiculum turns brown-orange in KOH. This seems to be a Dothidiomycete. But if I am wrong about that, it is a Sordariomycete with a very thick unitunicate ascus and a
Asci IKI-, 174-224 x 13.7-17µm.
Pores brown, muriform with mostly 3 transverse septa and 2 or more longitudinal septa. 13.3-20.5 x 9.7-11.5µm
Paraphyses narrow.
Any help would be appreciated.
Thanks,
Ethan
