The sequence wasn’t long enough to be particularly useful

Great observation Joan

Hopefully you can post the herbarium record number and ITS sequence at some point as recommended by the NAMP.
Hygrocybe chlorophana by appearance and ITS sequence

The top two photos are consistent with H. chlorophana – golden colored & viscid. I’m uncertain of the lower two photos. The ITS sequence matches verified collections of Hygrocybe chlorophana.
I corrected the consensus sequence and obtained 681 readable bp (pasted below) of which only 8 were exclusive substitutions or single bp indels (1.1% difference) from a sequence of H. chlorophana from Tennessee (GenBank FJ596922 collection DJL06TN16) and 19 hard bp (2.8%) divergence from Kew H. chlorophana (mis-identified as H. flavescens, which doesn’t occur in Europe, GenBank EU784301)


In contrast there were 66 ‘hard’ substitutions and indels out of 706 bp (9.3% divergence) when compared to the consensus of two H. flavescens sequences from Tennessee (DJL06TN25 seq. by K. Hughes and SC-19 seq. by Rizzo)
