Hi there,Collected in Belgium on twigs of Cytisus scoparius:
Pycnidia semi-immersed, scattered to gregarious, subglobose, 0.3-0.4 mm diam., black, extruding a black creamy conidial mass.
Conidia subcylindrical to slightly barrel-shaped,, with truncate ends, 4-11(19)x(1.5)2(2.5) µm, smooth, with thin blackish wall, eguttulate, occurring in disarticulating, unbranched, short chains.
Ass. Schizoxylon compositum (Stictidaceae).
Based on the conidium morphology, it might be a Phacidiella sp. Although Phacidiella has hyaline conidia, Crous et al. (2007) introduced P. eucalypti, a species with pigmented conidia and moreover phylogenetically allied to Stictidaceae. Purely coincidental?
Your comments/help is welcome.
Best regards,
Bernard Declercq

Re : Coelomycete on Cytisus scoparius
Hello,
did you consider genus Hormodochis? (H. melanochlora but perhaps others too) It might be the anamorph of Schizoxylon. In GenBank, H. melanochlora from CBS (KP004487) has 98% match with Guy Marson's Schizoxylon sp. from LUX (OM891651).
I've seen here similar anamorphs on several woody plants (Ulmus, Populus, Rhamnus, Humulus...), no idea whether they all are the same species or not. I don't have any practice with Schizoxylon and cannot culture them anyway.

Hello Viktorie,
Thanks for your suggestion.
Indeed, Hormodochis melanochlora could be a match.

... and yes, I was too fast. I see now that Crous recombined his Phacidiella eucalypti into Hormodochis eucalypti (Crous) Crous 2020.
