Hello dear Forum.

This very early species was found today on catkins of Populus tremula, on road side in mixed coniferous-deciduous forest. It is still snow in the forest, but south slopes are exposed and there was the fungus fruiting.

It goes to C. caucus using Nordic Macromycetes (2000) key, but the spores in my specimen are some larger.

Asci 155 (140-180) x 10.5 (10-11); paraphyses cylindrical, slightly enlarged in upper part, 3-3.8 broad there; spores 11.7 (10.8-12.3) x 6.7 (6.3-7.1), Q=1.74, n=23.

Hello Nina

this spore size is fully o.k., see my drawings on Salix.

Those on Corylus and Alnus have smaler spores and are a different species, C. amentacea.

Probably Nordic M. mixes both, also they probably give dimensions of dead spores.

I usually find the species on Salix, while on Populus , the type substrate, it is not often collected.
