Vitus SchäfftleinHello, I found Trochila ilicina on Ilex aquifoliu
Orbilia tremulae?

Hello,I've found this Orbilia on wet decorticated wood (probably Salix), on the ground.
Only a little refractive exudate on paraphyses top + scattered on cells near margin.
Uppermost spore mostly with SB up, but not always (3rd ascus from left is with SB down).
I'm not sure if the anamorph belongs to it.
Given the habitat and spore size, could it be Orbilia tremulae? Isn't it too much orange?
Thank you in advance.
Viktorie

Re : Orbilia tremulae?
Hi Viktorie
Could be, but sure we cannot be. These fusiform spores might be ascospores?
The Dicranidion conidia of O. tremulae would be characteristic.
O. tremulae is probably a common species, but I am often not sure, and our concept is only tentative. With DNA it would be easy - or with a culture or conidia from near apothecia.

Re : Orbilia tremulae?
... das hätte ich (früher) als coccinella bestimmt. Aber vermutlich ist dies eine Sammelart geworden, wie so vieles.

Re : Orbilia tremulae?
Ja, das ist kompliziert geworden. O. coccinella ha hörnchenförmige Sporen in 16-sporigen Asci. O. tremulae hat eigentlich als NFF das japanische Dicranidion inaequale, aber das passt nur morphologisch. Neben der häufigen O. eucalypti gibt es noch ein paar weitere mit ellipsoiden bis subglobosen Sporen.
