Pyreno with long neck + IKI blue
Daniel Ghyselinck, 26-03-2021 21:13
Found on hardwood, plenty of these long necks arising from the bark.
Difficult to have a good photo of the ascus, there are probably very thin. The apical pore is slightly blue in IKI.
Spores small, variable in shape and size, 3,5 - 6 x 1 - 1,8 µm, often slightly bent, sometimes strongly, pale yellow brown under the microscope.
Looks like Togninia minima, but the ascus blue in IKI does not fit.

Thanks and best regards,
Daniel

Re : Pyreno with long neck + IKI blue
Hi Daniel
Did you consider the possibility it might be Peroneutypa heteracantha (Eutypella scoparia?

Re : Pyreno with long neck + IKI blue
Hello Enrique,

You are absolutely right, and I am unforgivable for not having recognized it!
But I had always seen this species in compact clusters, and I had no idea that the asci reacted in blue with IKI. I just saw the micro on your site, completely compliant.

Thank you!
Daniel
