small discomycete with lichen-characters

... found on wood of Fagus sylvatica (without any algae) in the Bavarian forest.


The small asci are thick-walled and react with IKI strongly blue - but not the wall, but the inside of the ascus.


Who has an idea of this fungus?


Best regards from Lothar

Re : small discomycete with lichen-characters
Hi Lothar

the blue reaction is the tholus of the ascus, the thickened ascus wall which is much thinner in living asci.

I can hardly believe your scale, such minute lichen asci I never heard or saw.

Re : small discomycete with lichen-characters

Hi Zotto,


I am also somewhat bewildered that I find so many fungi with minute asci and spores (H. hemiamyloideus, the pyrenomycete, and this disco). But my scale should be o.k., as other fungi like for instance Flammulaster, Entoloma or Mollisia (possibly I will post one soon) have "normal" results.


My fungus, by the way, is no lichen. There are no traces of algae on the substrate, nor in the apothecia. It is related to lichens, o.k. - but no lichen.


Thank you and best regards from Lothar

Re : small discomycete with lichen-characters
o.k., but when I look again at the spore photo I imagine your microscope has a resolution of 0.1 µm or less. Spores with 1.1-1.3 µm width I never saw such big and with such thin cell wall. Couldn't it be that you used a 60x objective and the scale for 100x?

Re : small discomycete with lichen-characters

... sorry, I do not have a 60x-objective. I have used the cut-function in my BMS-program, but also have similar results with the smaller spores on larger pictures without cut. And Hyphodiscus has realistic measures - or not? And - the asci and spores were definitely very small.


Regards from Lothar

Re : small discomycete with lichen-characters

... oh shit ... - sorry!


I see the cut-function brings a false result when measuring the fotos taken by it - what a shit!


So - Zotto is, as almost in every case - right.


The measures are too small.


I give an original picture with - hopefully - more realistic values.


Regards from Lothar - and sorry again


P.S. The same mistake is likely in my pyrenomycete post. I will go back to this later.
