This small (< 1.5 mm diameter) white Hymenoscyphus was growing on very moist leaves of Clethra arborea in Madeira, Ribeira do Seixal.
Asci octosporic, IKI+, with croziers and Hymenoscyphus-like apical apparatus, (80.9) 82.8 - 95.9 (103.8) × (8.4) 9.4 - 11 (12.1) µm; N = 36; Me = 87.7 × 10.4 µm in vivo.
Ascospores ellipsoidal, with a central septum, slightly constricted at the septum, with some small to medium LBs, (10.2) 11 - 13.3 (13.9) × (3.8) 4.1 - 5 (5.7) µm; Q = (2,1) 2,4 - 3 (3,3) ; N = 60; Me = 12,2 × 4,6 µm ; Qe = 2,7 in vivo.
Paraphyses cylindrical, septate, but without VBs.
Ectal exciple with textura prismatica, with very short cells. Medullary exciple with textura intricata.
With Baral's keys I arrive at Hymenoscyphus "calycinoides", but I don't see VBs in the paraphyses and it seems that the species is not published, at least under that name.
Many thanks in advance.
Miguel Ángel Ribes.


Despite the absence of VBs, it seems there is no other possibility, right?
I will turn the table around, thanks.


Thanks Zotto
