Rutstroemia sp.

Pavol Palo, 13-02-2015 15:33

Hello, dear friends.
Thank you in advance for your assistance, or some idea

I found this one on part of cone Abies alba at the end of september.
Apothecia with short stipe : diam. 1-2 mm
Spores : 8-20 x 4-5 µm
Ascii:85-110 x 7-10 µm
Paraphyses: diam. 2-3 µm

Re : Rutstroemia sp.

Hello

I assume you mean 18-20 µm

I suppose this is Hymenoscyphus epiphyllus. You can test iodine for the ascus apex which is certainly not sclerotiniaceous.

Re : Rutstroemia sp.

H. epiphyllus is plurivorous on everyting, not only leaves, also wood and cones.
