Hi.
Found in Rotlia Naturreservat in Norway 13.10.2015, on a 1 cm thick decorticated branch of Juniperus communis.
I measured spores on 2:
No1: 16.6 [19.3 ; 20.9] 23.7 x 8 [9.1 ; 9.7] 10.9 µm, Q = 1.6 [2 ; 2.3] 2.7 ; N = 20 ; C = 95%, Me = 20.1 x 9.4 µm ; Qe = 2.2
No2: (17.5) 18.9 - 20.7 (21) × (6.5) 7.3 - 9.3 (9.8) µm, Q = (1.9) 2.1 - 2.5 (3) ; N = 25, Me = 19.7 × 8.5 µm ; Qe = 2.3
Spore wall (0.7) 0.71 - 0.8 (0.9) µm thick.
Asci: (94) 96.6 - 135.6 (149.4) × (14.9) 15.2 - 17.6 (18.1) µm, Q = (5.2) 5.6 - 9 (10.1) ; N = 16, Me = 108.6 × 16.3 µm ; Qe = 6.7
The spore wall dimension leads me to Propolis leonis, but the spore size do not fit the description in Baral's key, but it corresponds better with Markéta Šandová measurement. P rhodoleuca is another candidate, but do not have that thick spore wall.

Is it P leonis with small spores/not fully grown spores?


Regard

Re : Propolis
I think this fits quite well P. rhodoleuca. Your two spore measurements are in water or KOH?

Looks like it is new for Norway:-)
Thank you for identification.
