Hyaloscypha (?) on Picea resin
Edvin Johannesen,

Very small (up to 0,2 mm diam.) whitish apothecia on resin from Picea abies (Norway). Short (~as high as diam.) stems. Ascospores 6-8 x 3 microns, with two refractive bodies, ellipsoid to broadly spindle shaped. Asci not discernable. Short hairs, approx. 40 microns long (?), with some sort of incrustations. Stem base pigmented, pseudoparenchymatous. Iodine reaction not checked. Mounted in water (dry specimen, a week old). Three of photos in phase contrast to enhance visibility.
Are we in Hyaloscypha? Any clues appreciated.
Thanks!

Re : Hyaloscypha (?) on Picea resin
The only published resinicolous species that is close to this at all is Hymenoscyphus resinae-piceae, I think. The description doesn't seem to match, though. There is a link here: http://www.indexfungorum.org/names/NamesRecord.asp?RecordID=131033. But, perhaps what you found is something that is not obligately resinicolous.

Re : Hyaloscypha (?) on Picea resin
Thanks, James. You are right - the description of Hymenoscyphus resinae-piceae doesn't quite fit, and yes, my collection may not be obligately resinicolous.
Cheers!
