White apothecia on Picea abies resin

Hi!
These tiny white apothecia (presumably) were found on resin (Picea abies). I first thought they were Hyalorbilia resinae, which has been found in Norway once before (ID by Baral), but in the microscope I only see masses of globose conidia (ca. 2 microns in diam.) formed in chains in a palisade of slightly curved conidiogenous cells. Any thoughts? (Sorry about the poor micro image quality.)
Thanks!

Dear Edvin,
It looks like Dendrodochium citrinum which can be cimpletely white sometimes.
Cheers,
Stip
