The observation data rightly says ‘Seen at’ (not Collection Location), but it still shows up in the Occurrence Map, which gave me a surprise until I read the notes here.

Is this supposed to happen? I thought collections that had the ‘Is Collection Location’ box unchecked didn’t show up on the OMs.

corkscrew hyphae in the pilipelis…
