Sometimes you can only tell which genus a fungus belongs to, not the exact species. Field Mycologist UK lets you record it at genus level rather than guess.
What Is a Genus-Level ID?
A genus is a group of closely related species. A genus-level ID says “this is a Russula, but I can’t tell which Russula“. Genus-level IDs are shown with the word Genus in front, for example Genus Russula.
When to Use One
- The photos don’t show the features needed to separate species.
- The genus has many near-identical species, such as Cortinarius or Russula.
- The species needs microscopy or chemical tests to separate.
- You recognise the genus but aren’t confident of the species.
Recording a Genus-Level ID
In the fungus search, choose the genus-level option (marked GENUS in the app). If it isn’t listed yet, type Genus followed by the genus name, for example “Genus Mycena”.
How Genus-Level Observations Work
- They’re recorded and shared like any other observation, and they show which genera occur where.
- They stay Unconfirmed. Genus-level IDs are never confirmed, and there’s no Agree button on one, because the aim is to reach a species.
- When someone suggests a species, members can agree with it. Once it’s clearly ahead of every other ID, the observation becomes that species and is confirmed.
- You can also change it to a species yourself by editing the observation if you work it out later.
Tips
- Be honest: a genus-level ID is better than a guessed species.
- Note the details: smell, taste, spore print colour and flesh changes in your notes may help someone take it to species.
- Ask for help: other members may be able to spot the species from your photos.
