Nectrioid fungus on Cornus
Eduard Osieck, 18-12-2019 19:35
This nectrioid fungus was found on a dead Viburnum branch still attached to a fallen shrub. The dark yellow perithecia (KOH+, 0,5 mm only 0,25-0,3 mm visible) were largely embedded in the substratum. The 7-septate brownish spores were rather large: 68-72 x 11-13 um. Intact asci not seen.

All suggestions are welcome!

Eduard

Re : Nectrioid fungus on Cornus
Hi Eduard,

this is Pseudotrichia viburnicula. Would be nice to have your collection details (date an location). This fungus is plurivorous, I think Cornus is a new host.


best regards

Martin

PS: if it is from the NL, there ia a collection from Steenbergen on Crataegus by Aafke Buijs in 2015.

Re : Nectrioid fungus on Cornus
Hi Martin,

Thank you very much for the prompt identification as Trichonectria viburnicola! Clearly, I was misled by the yellow (top of the) perithecium and the positive KOH-reaction.


Little information about this species in the literature but the more on this site including your document of the Heidelberg collection and your message in 2013. Yes my collection was done in the Netherlands, so this is the second collection after the one in Steenbergen on Crataegus.


Cheers, Eduard
