Propolis on Juniperus
Per Vetlesen,
11-07-2016 22:10
It was found on the bark of a dead Juniperus communis in Rotlia Naturreservat, Norway.
Spores (25.9) 28.8 - 33.2 (36.5) × (9.5) 11 - 13.4 (14.3) µm, Q = (2.2) 2.3 - 2.9 (3.3) ; N = 31, Me = 31.2 × 12 µm ; Qe = 2.6
Asci 127.1 - 141.18 (141.2) × (25.3) 25.33 - 31.16 (31.2) µm, Q = 4.1 - 5.2 ; N = 5, Me = 132.3 × 27 µm ; Qe = 4.9
Using H.O. Baral key I can't find any that fits exactly. I think the spores look like those of Propolis hillmanniana, but they are a bit too small and the same for the asci?
Thanks in advance for any comment

Re : Propolis on Juniperus
Hi Per
I think it is P. hillmanniana, yes. These propolis species show some variation and I have certainly not covered the entire scope so far. In fact, only a few species have such multiguttulate spores, and with that size I know nothing else. Conifer as substrate is also typical.
The type collection has extremely long spores (43-55), while a fresh collection that I studied had 31-45 µm, so I hope there are not much more species but only variation.
