I think I stand corrected….

Both the spore size and shape fits better with P. antillarum…

Microscopy added.

I don’t know which taxon this is but based on the data given by Byrain in a previous comment Panaeolus semiovatus var. phalaenarum has to be ruled out simply based on the spores dimensions.

This has a veil….

Meaning its not Panaeolus antillarum.

Edit: Missed a crucial word, “not”….

You can

check the spore size to further confirm.

2 Veil visible as dentate or appendiculate margin of the cap
(fugacious); spores elongated, in average reaching 20 (im
in lenght, little flattened (fig. 2 c); species of temperate
zones
…. Panaeolus semiovatus var. phalaenarum (2)
- Veil absent; spores more stocky and more flattened,
in average less 20 um (about 15-20 Lim long), similar
papilionaceus-type; species of tropical and subtropical
zones …………………… Panaeolus antillarum (3)

Also, images of the sulphidia would be really cool, but not helpful for identification.
