My Observation 109443 is larger and looks somewhat similar, but is microscopically very different. Still waiting for some DNA results for Obs 109443.

Interesting

Spores and cystidia are a good match with sambucina. The colours too – greenish yellow hue on the cap is a typical character. It’s no doubt that this is a close one, but not as large and sturdy as I’m used to see it.
Still, maybe close enough to be the same..?

Closest match of my ITS sequence …

for this Observation is GeneBank Accession number AM882757.2 Inocybe sambucina 18S (partial), ITS1, 5.8S rRNA gene, ITS2 and 25S rRNA (partial), specimen voucher SJ01002

I’ll post details this evening.

Can you be more specific and post what collection of Inocybe sambucina you are referring to?
