lol, the main way I identify mushrooms is with books - I don’t know any serious mushroom people that use apps, it’s all about taxonomic keys and using books to identify.

This is region specific - but look for identification guides for your region: en.wikipedia.org/…/List_of_books_about_mushrooms

In North America I highly recommend Alan Bessette’s books if you are serious about this.

You should find a local mycology club and join them - they will know what books to get for that region.
