Valsa on Salix
Karl Soler Kinnerbäck, 30-01-2022 20:13
Hi! 

Need help with this Valsa on Salix, Uppsala, Sweden, 2022-01-29. 

Sp. 14-19 x 2,5-3.    Asci 8-spored.

No stromatic line as far as I can see. Was thinking about V. ambiens or sordida. 

Best regards
Karl

Re : Valsa on Salix
Hi,
Probably V. ambiens because V. sordida usually has much shorter ascospores: 8-12 (-15) x 1-3 um according to Hayova & Minter 1998.

Re : Valsa on Salix
Hi Eduard,

Thanks for your suggestion! It sounds resonable. I actually found V. ambiens on Acer during the same field visit but that specimen had clearly wider spores (3-4), which made me wonder if they were really the same. Is it a reasonable variation in spore size?

Best regards
Karl
