20.6.25, on branch of Abies infected and thickened by Melampsorella caryophyllacearum (rust fungus-cancer), leg. C. Weinkötz in the scope of a fungal seminar, Germany, Baden-Württemberg, Schwäbischer WaldI think the fungus shouid be bitunicate, and the spores reminde me of Melanomma or something related. I do not find a fully fitting fungus in the book of Björn Wergen. The brown, 3-septate spores measure about 21-24/(6,5)7-7,5(8) µm. There is no reaction with Melzers reagent, and there are croziers at the base of the asci.
Who can help? Best regards, Lothar

very likely Cucurbidothis pithyophila var. cembrae - on Abies
Hello Angelo,
thank you very much for your proposal. This seems to be a very good hint - as far as I can find quick information in the internet. I also have the book of Migula who mentions Rehms variety (without longitudinal septa), and the data given sound good.
Best regards, Lothar
P.S. If somebody has acces to the following publication, this could be interesting:
Boyce, J. S., 1952: Cucurbitaria pithyophila, an entomogenous fungus. Plant Dis. Reptr. 36 (2), 62—63.
