Welcome to iNat! It certainly looks like the shaggy manes we get here in the US, but I don't know enough about Brazilian mushrooms to confirm.

Thanks! I loved this site, this is exactly what I was looking for. Easy to use, I'm only trying to find out if it can understand geotags... Have to try it out.
Well, about the Coprinus, I'm certain that this is an exotic species here in Brazil, brought with Pinus sp. or other trees from Europe or North America. Coprinaceae here are usually C. disseminatus and other alike. But that'd for the specialist to find out, I'm a computer programmer and naturalist since a little boy. ;)

iNat doesn't recognize photo geotags for direct photo uploads, but it will import coordinates from Flickr or Picasa if you use those services. I'm the main developer here, and recognizing geotags is high on my list of priorities, but I'm mainly working on backend updates at the moment. Frankly everything about the photo upload process could be improved a lot.

Hey, that's nice! My programming skills are a lot rusty, but maybe I could help a bit... I've been "fooling around" with Perl, PHP, Javascript, and other stuff! Some years ago I wrote a MySQL based photo database where I included coordinates, but I had a lot of trouble with EXIF data extraction and couldn't write them back, besides I had no time for writing an assembly routine for that (I'm a computersaurus, you see)... And then came picasaweb, panoramio, etc and I gave up my project. I think it is somewhere in one of my old HDDs. I guess I'll have to buy some programming books again! ;)

Well, if you're curious, iNat is built with Ruby on Rails, and our code is open source: https://github.com/inaturalist/inaturalist. If you're really interested in taking on something like this, message me on github and we can talk about implementation ideas.
