Durango Online Herbarium is finally up!
I’m uploading over a decade’s worth of wild plant and mushroom photos, along with where they’re found and some additional basic info. I’ve started with fungi, and next will be plants. For now, entries are arranged alphabetically. Keep checking back to see the new uploads. You can use the search feature in the upper right corner to look for specific mushrooms or plants. Note that many of the mushrooms and plants featured are not edible or medicinal so don’t assume you can stick ’em in your mouth just because they’re included in the herbarium.
