Phaeohelotium sp.
Nina Filippova, 02-02-2013 20:01
First identified this specimen as Phaeohelotium nobile with Nordic Macromycetes; then picked the key by Bernard Declercq from the previous discussions, and there it came to [P. pilatii] or probably P. monticola.

I do not see clear clamps there (i would say clampless), spores with gelatinous sheath (but not always), and there are abundant budding at maturing.


Collected on pine wood (Pinus sylvestris) in bog, N61,066591° E69,457326°, 07.09.2012.


Apothecia turbinate, with short stipe, hymenium surface convex, growing in clusters (2-4), 2,5-3,5 mm in diam, hymenium surface bright yellow, smooth, outer surface yellowish, pale, brownish at stipe base.


Outer layer of excipulum from textura globosa (at base) to porrecta (edge),  from thick-walled cells; asci cylindrical, long, with amyloid pore, about 167 x 9; spores very variable in shape, disarticulating in two parts, and budding when overmature, with gelatinous sheath (not in all spores), with several medium guttules and amorphous oil content, 1-2 septated when overmature, mean shape fusoid, with obtuse ends, measurement for 10 mean spores: 14,2 x 5,3; conidia at long stalks, 5 x 3; paraphyses cylindrical, not enlarged to the tip, rarely branched, many segmented (about 5-7 septa), without or with some minor guttules in upper part (but bad seen in rehydrated stuff), about 150 x 2,3.

Re : Phaeohelotium sp.
Here the spores also still look as if alive. And yes, the asci are clampless. This is certainly the conifericolous  P. pilatii, for which an earlier name is available: Hymenoscyphus eichleri. H. monticola has croziers and more elongate spores.

Re : Phaeohelotium sp.
Thank you.

There the spores were in water, and in KOH (in different pictures), the same "approximate <10" concentration.? The specimen was stored dry before.
