Yellow on short stem
Johan Myhrer, 28-08-2019 09:20
Central Sweden 26 august 2019 on decaying leaf and small twigs (Betula) on damp soil under a stump (Picea abies) on a mire (61°58'43.4"N 16°54'36.8"E).

Spores 20-22x5-6µm, mostly without septa, sometimes with one. No croziers. Paraphyses with many drops. The stem is darker in the lower part.

Thought this would be a Calycina, seems to be a Hymenoscyphus?

Re : Yellow on short stem

clearly a Hymenoscyphus (at least s.l.) and not a Calycina - because of the multiguttulate paraphyses - and the macroscopical appearance


Regards, Lothar

Re : Yellow on short stem
Yes, and the apical ring also excluded Calycina. If the asci are really without croziers it should be Phaeohelotium fulvidulum which may occur in a grey and yellow variant.

Re : Yellow on short stem
Thank you Lothar and Hans-Otto!

P. fulvidulum looks like a match. Is there a description somewhere?

Take my notes on the drawings :-) 

Yes, in Boudier Icones p. 253. I repot it also in my 1985 paper.

Re : Yellow on short stem
Thanks again Hans-Otto. I get cautious since P. fulvidulum is never reported from Sweden before, no searchable records in herbaria and nothing in Ove E. Erikssons cheklist from 2014. As a layman you don't really expect to find new species for Sweden every now and then :-D
