Chlorociboria on Fagus

Dear FriendsCan you tell me whether there are any environmental preferences of species Chlorociboria aeruginella, Ch. aeruginascens and Ch. aeruginosa? I would like to clarify for myself what same species from mentioned above are able to colonize wood of Fagus and cause its greening. I often find a timber devoid of fruiting bodies. Is it possible in this case to talk about any particular species name?
What other criteria besides the size of ascospores are important for these species delimitation?
At one of my samples I found ascospores the following sizes:
(12.3) 13,1-14,5 (15.3) x (2,0) 2,7-3,4. Could this be Chlorociboria aeruginella?
Grateful before,
Alex

Re : Chlorociboria on Fagus
Hi Alex
C. aeruginella is a species of herbaceous stems and leaves. On wood there is only aeruginascens and aeruginosa, which are indistinguishable from the green stain. But my data on substrate preferences say:
aeruginosa: Betula, Acer, ?Populus
aeruginascens: Quercus, Salix, Alnus, Carpinus, Fraxinus, Fagus, Laurus.
But Dixon gives also Betula for aeruginascens, and even conifers, and for aeruginosa? a very similar host spectrum.
Your spores perfectly fit to the more rare aeruginosa. Both species have short flexuous haurs but those of aeruginosa are warted, those of aeruginascens smooth.
