Lachnum virgineum (possibly immature).

Re:On Larix cones
I found no spores yet, but asci were about 30-35x3-4 micrometers and hairs up to 150x3-4 micrometers and seems to have something on :) (small spikes or something). I saw no septas.

Yes, the hairs of L. virgineum have a subacute tip when still growing. 150 µm is a bit much, are you sure? 100-120 is o.k. for mature hairs.

Re:On Larix cones
I loaned a microscope from the local university and now I've got to admit, that I'm not sure. With a new device I could have used a factor, that is too big.
I have found L. virgineum lot on deciduous trees and herbs, but not on cones.
I saw no lanceolate paraphyses, which would have revealed L.virgineum. I'll put them aside and wait for them to mature.
