Camarops on Quercus
Lothar Krieglsteiner, 09-08-2020 07:49
Lothar Krieglsteiner... 8.8.20, in the Eifel (Germany), on the same log with Daedalea quercina.
I would have thought this to be C. polysperma, but Quercus would be an unusual substrate. C. petersii is said to grow on Quercus. What are clear differences? I cannot find a good key including all species. Who can help - what have I to do?
The spores are mostly about 6-7/2,5-3,5 µm large. 5 % KOH (I do not have 10 % with me) dissolves a weak greyish (lilaceous?) pigment.
Best, Lothar
