Dear all,
a week ago this cushen formed species was collected as a side-catch with Lilapila jurana on Picea resin in Swiss Jura at 1030m. So far I don't get any further as that the thing microscopically resembles the Sarea species wit asci 110-120x 30-35 µm and filed with thousands spores sphaerical of 2µm.
I am open for any suggestion, thanks in advance.

Re : Sareomycete?
Hoi Stip
You mean the black disc on the lower right or these grey warted ones?
Actually I am not sure with the spores. Alternatively the asci are immature and full of LBs? Did you see free spores?
Sarea reacts deep blue in IKI (entire hymenium), probably turning reddish at high concentration..

Re : Sareomycete?
This looks like spores, but the macro-appearance is not that of a Sarea.
Perhaps you could test the KOH-pretreated IKI reaction, if the blue obscures the entire ascus or is only a faint reaction which would be untypical of Sarea.
The apos with their small opening look immature but in section they appear exposed.

Re : Sareomycete?
Ha, this would surprize me, never seen such apos! Did you compare the black ones with the mic?

Re : Sareomycete?
Did you have a look at Mitchell et al. 2021? There Sarea is restricted to black ones and Zythia are the yellow-orange ones.
The ectal excipulum in both is a clearly vertically oriented texture, unlike yours. Also the macro is totally differnt from your grey ones.
I also see differences in the paraphyses, being straight, distinctly thicker and densely septate in Sarea.
I would appreciate James Mitchell's opinion.

Re : Sareomycete?
Phh, I have now problems to follow. Which green one? Your new micros with a living ascus are from the black ones? It is always a mess with these fungi growing so close together.

Re : Sareomycete?
Hoi zotto,
according to James Mitchell it should be an undescribed species and it was on ascofrance before.

Re : Sareomycete?
When they are pseudothecia, why is the disc broadly open in section?
Is there any microscopy of the previous find?
