rosy-pink hyphomycete staining the wood (weakly) pinkish

... found in the Bavarian Forest near Frauenau, about 1000 m NN, on a decorticated log of Fagus sylvatica lying in the sun.


First we noted that the wood was partially weakly stained pinkish. In the section of the wood, however, the staining could not be observed.


Then we saw that at some places there were rosy-pink concretions, and we took it home.


Under the microscope first we could see it is an anamorph thus many small conidia made the picture. The "excipulum" (I don`t know if such a term is correct at hyphomycetes) consists of globose, incrusted cells. After staining with Congo-NH3 I could see the spore-building hyphae that were stained in the agent. This hyphae are a bit gnarled - and if I am not fully drunk I imagine to see clamp connections. Unfortunately, I have not a lot of experience of hyphomycetes. But this means it should be a basidiomycete.


Perhaps somebody can give a hint, anyhow?


Regards from Lothar


P.S. I googled "hyphomycete staining wood pink" and found a species with the name Arthrographis cuboides. I did not find a lot about its anatomy, but the conidia seem to have a similar form. But - the pictures in the net show a fungus that strongly stains the wood inside. And - it is an ascomycete ....
