Libertella on Quercus

In the Eifel National Park I also found this anamorph - it looks like Libertella faginea to me, but it grew on Quercus. I do not find an Eutypella (Libertella)-species growing on Quercus. What do you say?


Best regards from Lothar

Hi Lothar,
Did you check Phomopsis? I've noticed some samples might only have alpha-conidia's, so why not some with beta-conidia's only? It seems to me I see a single alpha-conidia.
Maybe put another conidiomata under the microscope, one never knows.

Proportions of alpha and beta conidia's are maybe dependant of climatic conditions of the period of sampling. It's the hypothesis I make after following some stations.

Cheers - LUC.

Re : Libertella on Quercus

Hi Luc,


thank you very much for your proposal - and: you seem to be right.


Only today I found the time to put another piece of the fungus under the lens. First I (again) thought there would be only one sort of conidia - millions of the long, curved B-conidia.


But after some search I found few (only at about 5 or 6 places in my slide) other conidia that could perhaps be the A-conidia of the Phomopsis. They measure about 10/2 µm.


Phomopsis belongs to Diaporthe - then on Quercus to D. leiphaemia? What do you think?


Best regards from Lothar
