Probably due to synonyms…

There have certainly been people who have considered O. illudens a synonym to the older O. olearius, so that might be why the name has been used for Florida material. It would definitely be interesting to start recording spore sizes and of course keeping specimens. This is actually another really good example of nearly cryptic species. They really are very distinct genetically and there are morphologically very distinct species more closely related to each of them.

I can live with the recommended name change. The guide I was using claims both o. illudens and o. olearius have been reported in Florida but are only distinguishable microscopically from the spores. Now I could kick myself for not saving some spores to look at. I will try to contact the guidebook author to see where his info came from.
