Mushroom Observer is a collaborative amateur mycology website started by Nathan Wilson in 2006.[1] Its purpose is to "record observations about mushrooms, help people identify mushrooms they aren’t familiar with, and expand the community around the scientific exploration of mushrooms".[2]

The community of about 4,000 registered users collaborates on identifying the submitted mushroom images, assigning their scientific names by means of a weighted voting process.

All photographs are subject to a Creative Commons license that allows their reuse by others without the need for remuneration or special permission, subject to the terms of the license.[2] The software is open source and hosted on GitHub.[2]


As of 2013, the website contains about 126,000 user-submitted mushroom observations illustrated by 335,000 photographs.[3] In 2010, the website contained about 53,000 user-submitted mushroom observations illustrated by 101,000 photographs; up from 7,250 observations and 12,800 photographs in 2008.[1] On March 2016 Mushroom observer offers approx. 600,000 photos and 200,000 observations.[4]
