Not semiovatus

These mushrooms are definitely not Panaeolus semiovatus var. phalaenarum. One reason is the spore size – That species has spores that average 20 micrometers long, while these are no longer than 14 micrometers. Also the spore shape is wrong for P. semiovatus var. phalaenarum – that species has relatively narrow spores for Panaeolus, while these spores are relatively wide. Another reason is the lack of veil remnants around the cap margin, which is an identifying feature of Panaeolus semiovatus var. phalaenarum. Panaeolus antillarum is a much closer match. Your concern about links to the shroomery is a bit unusual since you have posted there over eight thousand times.
