Hymenoscyphus on branches of rubus?

Hello,
I found these stalked species on dead rubus branches. They are ivory coloured, not reddening when damaged and measure between 1&1,5mm. Spores are scuteloid 3,5/4x19/25µm and the asci are 6/10x95/103. Can anyone tell me what this is?
regards,
Ralph

Re : Hymenoscyphus on branches of rubus?
I would place it in hymenoscyphus scutula, despite the apparent absence of distinct bristles at the spore ends.

Hello Zotto,
thanks for your answer. I don't see the reddening either. Can it be because my sample is already 1 week old?
PS I will take again a look at the spores to see if I can find any bristels.

ralph

Re : Hymenoscyphus on branches of rubus?
Did you read about reddening? On your photpo I see slight red-brown areas. This is by oxidation of the guttules (VBs) in the paraphyses, and a general feature in Hymenoscyphus.

no I didn't read about reddening but I saw it in a key to this genus. sorry, my mistake
