White apothecia on Picea abies resin

Edvin Johannesen, 29-04-2021 17:41

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!
