Libertella faginea or Phomopsis quercella? => Libertella faginea

Hello forum,

Found 05-07-2018 in woodlane with fagus and quercus.

We think the host is fagus but are not 100 % sure ...

On fagus:

Ellis & Ellis, p. 136: Libertella faginea: "conidia curved, hyaline, mostly 15-19 x 1-1.5, issuing in long twisted, glistening honey-yellow tendrils or sometimes broad ribbon-like bands. Very common on trunks and branches. July-Oct."

Teleomorph:  Eutypella quaternata

On quercus:

Ellis & Ellis, p. 219: Phomopsis quercella: "conidiomata becoming erumpent through longitudinal slits, black. A-conidia fusiform, pointed at each end, biguttulate, hyaline, 8-12 x 2-3   B-conidia curved or hooked, 20-30 x 1.5-2   On dead twigs."

Teleomorph: Amphiporthe leiphaemia

Libertella faginea fits well .....

Greetings, Riet
