- https://mushroomobserver.org - crowdsourced database for mushrooms.

- https://www.inaturalist.org/observations - plants and animals.

I love iNaturalist and am sometimes blown away by the automatic suggestions. I use it for birds, plants, bugs, mushrooms, trees, everything. Some time ago they added audio clips as well. It would be great to see more of these open communities inter-connected and sharing their databases.

Most of these platforms contribute their GBIF which aggregates it together. I contribute my sightings to iNaturaliast, but when I need the data for occurrences pull GBIF. I think this is perfect, because each site can compete on the best reporting interface, while not fragmenting data for data consumers.

https://bugguide.net - this one is awesome. has photo submissions for identifications

Sadly, bugguide is less useful to me here in Singapore. As stated in the header for the site:

> Identification, Images, & Information

> For Insects, Spiders & Their Kin

> For the United States & Canada
