Growing within 10 ft of 2 Prairie fringed orchid. someone pointed out that it could be the Platanthera leucophaea x lacera hybrid. was quite robust for the P. lacera Im use to seeing. Ohio.

At its only known site in Ohio. Curiously not known from Kentucky just across the Ohio River.

These are growing in tiny black patches on dried Picea sitchensis resin on the trunk. 1-2mm tall with head ~500um. @jameskm @tcurtis any ideas?
