Orbilia septispora? on Salix
Viktorie Halasu,
15-12-2021 16:12
Hello,this Orbilia seems to be somewhat similar to O. quaestiformis, but I think it could be O. septispora (septate spores in living asci, short SB, LBs in spores). What do you think?
Growing on 1cm twig of a shrub Salix, on decorticated wood. Periodically wet meadow near a riparian forest, 220 m elev., soc. Calycina cf. vulgaris.
Apothecia 170-200(250) um in diam (dry?). Rather variable paraphyses' shape. SCBs only globose in both excipulum and paraphyses. SBs vermiform / subulate, in older(?) spores tear-shaped. Lower spores inverted.
Thank you for any advice.
Viktorie

Re : Orbilia septispora? on Salix
Yes, no doubt! It is rare that this species occurs on wood.

Re : Orbilia septispora? on Salix
Thank you for confirmation! I've seen that (temporarily) intermediate collection on a Salix pole (under quaest.), so I had some doubts, but the coll. of septispora from Hradec Kralove on Juglans looked more similar to this one. There's a lot of Phragmites around, hopefully I will eventually find septispora on it's usual substrate too.

Re : Orbilia septispora? on Salix
It was strange that the holotype (first collection) was on a Melilotus stem, though in a Phragmites stand.
