Psilachnum on Phragmites
Viktorie Halasu,
07-01-2022 22:45
Hello,last year I've found this Psilachnum on old Phragmites leaves, apothecia (220)330-395(500) um wide, shortly stipitate.
Paraphyses broadly lanceolate, protruding.
Asci up to 4.6 um wide, H+ (LUG not tested), Psilachnum-guttule not seen.
Hairs in fascicles, not much narrowed to the tip.
Is it P. acutum? P. schoenoplecti should have different hair tips. leg. 24. V. 2021.
Thank you in advance.
Viktorie

Re : Psilachnum on Phragmites
Yes, P. acutum seems good. P. schoenoplecti has much longer multiseptate hairs. I know both with VBs, however.
