Join fellow citizen mycologists on their mission to fill in mushroom research gaps (notably, more than 95 percent of the world's fungi species remain unknown to science) by returning to this feature from the 02-28-2020 Scout Report. Mushroom Observer exists to record observations about mushrooms, help people identify mushrooms they are not familiar with, and expand the community around the scientific exploration of mushrooms (mycology). The site functions as a sharing space for mushroom experts and enthusiasts alike. Not only can users enjoy the existing content, but they can create a free account to add their own contributions. As of this write-up, the site has over 40,000 members who have contributed more than one million images and more than 400,000 observations. Users may want to start on the How to Use page, which provides tips for navigating and adding content, as well as a Concepts Glossary that defines terms users will encounter as they explore and contribute to the site. The site is searchable using the query bar at the top left, or by clicking on the Advanced Search (where they can filter by result type, add restrictions by location, and more). Visitors can also navigate using the menu on the left-hand side. The Indexes section has a plethora of tools, including a Glossary page (that contains definitions, many with pictures, of hundreds of mycology terms) and the Institutional Fungaria list (showcasing fungi collections around the world).
