... on decorticated wood of Picea, near Snasa, Bergsasen, 6.7.22. The spores are about 15-19/6-7 µm large. I did not notice that this was lichenized, but I do not find another solution. Can somebody confirm my supposition? Yours, Lothar

I also believe. This paper should be consulted:
Spribille T., Resl P., Ahti T., Pérez-Ortega S., Tønsberg T., Mayrhofer H., Lumbsch H.T. 2014. Molecular systematics of the wood-inhabiting, lichen-forming genus Xylographa (Baeomycetales, Ostropomycetidae) with eight new species. Symb. Bot. Upsal. 37(1):1–87.

Hello Marta and Zotto,
thanks for your opinion and comments.
The link Marta gives is very similiar to what I have, but I did not notice such a splendid IKI-positive reaction.
The paper Zotto states I just downloaded. If I get much wiser with it I will write again.
Yours, Lothar

Hi Lothar
you must know that lichenologists write "KI" for what I use to call KOH+IKI. You must only pretreat with KOH, then you get the deep blue.
