I found and collected this propoloid ascomycete scarcely growing on the bark of a living tree (Pinus sylvestris) on the 12th of December, this year. It was found in the same area as my previous post (Fagerfjell, municipality of Flesberg, Buskerud county), but on a different locality. This locality is an open, old, pine dominated forest about 610 m.a.s.l.

The ascospores are cylindrical to ellipsoid and are filled with small guttules.

19,2-27,2 x 11,2-14,4 µm

Me= 21,9 x 12,31 µm

The spore wall is about 0,96-1,5 µm (living) and 1,7-2,8 µm (dead)

The asci are about 126-147 x 18 µm (dead)

The spores were measured in the living state, but I was unable to obtain a spore print. The large variation in the spore measurements may be due to some of the spores being partially immature. All measurements were taken from fresh material in water.

Although the spores are a bit small I believe that this resembles Propolis leonis quite well. However, that species has primarily been recorded in areas close to the coast. Could this be the right species, and is anyone aware of P. leonis or a similar species being recorded from submontane regions inland?

Thank you in advance and best regards,
