Rutsroemia fruticeti?
Zuzana Egertova, 19-08-2019 22:48
Zuzana EgertovaHello,
I would like to consult this inoperculate asco.
Apothecium 4.7 mm broad, 0.72 mm high.
Asci are 8-spored, have croziers, IKI+ (tested without KOH pretreatment).
Ascospores 18-21.2 x 4.6-6 micrometers, hyaline, smooth, often curved, with up to 3 septa, sometimes with apendages at poles.
Paraphyses contain brown pigment.
Medulla t. intricata, 330-400 micrometers thick.
Ectal excipulum t. porrecta, 40-60 micrometers thick.
Hairs rusty brown, roughened, septate, cells 5-9 micrometers wide.
Single apothecium on soil, no twig was visible. Austria, 300 m asl.
Thanks, Zuzana

Re : Rutsroemia fruticeti?
maybe I'm wrong, but what speaks against R. echinophila? I found that one growing seemingly on soil, but there was Quercus cerris cupule buried beneath it.

Re : Rutsroemia fruticeti?
The curved spores and non-gelatinized excipulum speak for echinophila. yes.

Re : Rutsroemia fruticeti?
Thank you! I somehow had in mind R. echinophila grows on cupules of Castanea, which wasn't growing in the locality, but now I can see it can also occur on Quercus. Z.
