anamorphic ?Ceratostomella or similar - on Abies

... found today in the Bavarian Forest near Frauenau, Germany, altitude about 1000 m NN, on bark of lying log of Abies.


Unfortunately I found no asci but only a lot of hyaline conidia - but with a quite special form, and about 11-14/2 µm large. The conidia have a lot of minute droplets (as long as alive ...).


Can somebody help - or is it hopeless?


Regards from Lothar

Hi Lothar,
if one assumes that your conidia might be immature asci and the minute horseshoe-shaped things floating between them ascospores, and considers the long beaked gragarious ascomata, Calosphaeriales might be a lead.

Re : anamorphic ?Ceratostomella or similar - on Abies

Hi Jacques,


thank you very much for your proposal of unripe asci!


But - I think this cannot be right.


First: there were a lot of (hundreds of) that "asci" floating, and not much more to see at all - like it is typical for anamorphs. And all looked more or less the same, this speaks claearly against unripe asci. None of the "asci" showed a second cell or what has ruptured from a second cell, all were more or less "sperma-shaped". The droplets inside the conidia were of perfect roundish form (as far as one could see this - they are minute) - what also speaks against unripe asci but for a ripe and healthy structure.


No - I really think it is an anamorph.


Best regards from Lothar


P.S. I try to find this fungus again - in the teleomorph :-)
