Propolis hillmanniana or farinosa?

Hello - and happy new year.  This Porpolis was collected on what is believed to be a twig of Picea abies.  Spores (only the relativeliy thin-walled ones measured) are 33-41 x 14-15 microns in water.  Asci are 20-27 microns across. Spores, when mature have many minute guttules and 1-3 large LBs. The largest ones up to 11 microns.  Spore and ascus size should indicate P. hillmanniana, but I am unsure about the LBs.  Micrographs in water, 1000x, scale ca. 1 micron.

White ascomata fresh, pink ascomata dried.

Re : Propolis hillmanniana or farinosa?
From spore size and also spore contents clearly P. hillmanniana. P. farinosa has max. 10 µm and betulae max. 12.5 in my key.

In which area did you collect? Perhaps you saw Hedmark in Norway as record. Found today or last year?

Re : Propolis hillmanniana or farinosa?
Thanks a lot! It was found in fall 2018 in Oslo region. Yes, I am aware of the finding my good friend Per Vetlesen made in Hedmark. This is the second record from norway, then.  I have used your key dated Jan. 2015.  Is that the most recent version?
