Lachnellula subtilissima?
Juuso Äikäs, 10-03-2021 10:39
During last winter I collected some Lachnellulas and it seemed that L. subtilissima was clearly the most common species. I collected it both from Picea abies and Pinus sylvestris. This one was growing on the latter substrate, on a fallen branch. 

I only have microphotos of spores left and wonder if it can be said only on the basis of spores that this is L. subtilissima or not? The spores measure 6.7 - 8.2 × 2.5 - 3.1 microns.

Re : Lachnellula subtilissima?
The spores look too wide for me. Important is the iodine reaction of asci and the ascus base.

Spore size reminds me of L. calyciformis, but shape and lacking drops are contradictory.

Re : Lachnellula subtilissima?
Ok, thanks. Too bad there isn't other info left. If I correctly remember, both the iodine rection and croziers are variable in L. subtilissima.

Re : Lachnellula subtilissima?
Yes, if we really have to do with only one species.

Re : Lachnellula subtilissima?
How about Capitotricha bicolour? aka Dasycypha bicolor. It looks exactly like your little discomycetes. As mentioned microscopy is essential to be sure. Your spores would do for this species. I attach the figure from Boudier which does seem remarkably like your nice picture of the cups aligned along a small dead branch.

Re : Lachnellula subtilissima?
Maybe Pinus sylvestris as a substrate would be a bit strange? If I remember correctly, C. bicolor is restricted to deciduous trees.

Re : Lachnellula subtilissima?
Good point.  It is usually on oak. But substrates can change in the fungal world. With DNA we aught to be able to tell if there is a switch or the species were actually the same all along.

Re : Lachnellula subtilissima?
Actually DNA is available for various substrates of C. bicolor, and the result is that there exist a number of species, including my old C. fagiseda (see paper about C. attenuans in Ascomycete.org 2019). ITS is partially very different among these cryptic species. But never I saw a fungus on conifer with such lanceolate protruding paraphyses.
