Lachnum fasciculare?
Filip Fuljer, 30-05-2023 11:00
Filip FuljerHello everyone,
I need your help once again, I found some Lachnum species on decaying wood of deciduous tree, which I cannot properly identify.
Locality: Slovakia, Central Europe, Petrovice village, abbrev. +- 370 m, south facing slope, deciduous forest (Quercus sp., Crataegus monogyna, Acer campestre, Populus tremula, Prunus spinosa, Cerasus avium), under robust Quercus sp. and Crataegus monogyna, well hidden in litter (leaves, small twigs, acorns...), on decaying wood of deciduous tree (probably oak)
_______
Apos - white or faintly creamish colored, after touch turning color to lightly brownish red, 1-3,5 mm broad, with stipe (not sessile).
Spores - fusiform, OCI 0-1, 7-10,1 x 1,8-2,2 µm
Asci - 8 spored, with croziers, 53,2-65,5 x 4,3-5,4 µm
Paraphyses - lanceolate, with strongly refractive VBs, protrunding asci 25-36 µm, thickness of p. - 4-5,2 µm
Hairs - endings slightly capitate or distrinctly clavate, septated, covered by warts, with VBs, 67-77 x 5,1-5,4 µm, without oxalate crystals

Thanks a lot,
Filip

Re : Lachnum fasciculare?
Yes, this all sounds like L. fasciculare. Quercus you can easily distinguish by its large pores arranged in rings.

To my knowledge there is no sequence in GenBank under that name.
