Propolis sp. on Pinus sylvestris
Hulda Caroline Holte, 29-12-2025 10:15
Hello,

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,


Hulda

Re : Propolis sp. on Pinus sylvestris
Dear Hulda,

I collected P. leonis on the bark of Pinus sylvestris in the mountainous regions (Karawanken) of Carinthia, Austria, so quite far from any coast. I briefly mention this collection in the following article: https://www.zobodat.at/pdf/CAR_207_127_0449-0492.pdf. It seems to be rare in most areas of Austria since I've not been able to find it elsewhere.

Best wishes,
Gernot

Hi Hulda, 

You are right, the species was at first mainly found near the Atlantic coast but a former post on Ascofrance already showed a much larger distribution (includinc Gernot's find) 
See : http://www.ascofrance.fr/search_forum/70642

Amitiés Michel

Re : Propolis sp. on Pinus sylvestris
Thank you all for your answers, they are greatly appreciated.
To know that the species is recorded far away from the coast in other countries is very interesting.

I am confused about whether or not the two latest comments on the topic from 2021, that was linked to by Michel, was directed towards my post or to the one from 2021? Is my specimen certainly P. leonis, according to the current species concept?

Kind regards, Hulda

Re : Propolis sp. on Pinus sylvestris
I collected Propolis leonis twice - in Liguria (Italy) and in the French Sea Alps, both times quite far from the sea coast.
Yours, Lothar
