FunDiS West Coast Rare Fungi Challenge
Keep adding your observations to iNaturalist OR Mushroom Observer!
How are the West Coast Challenge species selected?
Blog post by Else Vellinga - July 15, 2021
Help us find and document a target list of rare, under-documented or potentially threatened fungi. Scientists and conservationists need more data on these fungi in order to better understand and protect them. Your high quality observations can make a difference.
The West Coast Challenge Region:
4 States: CA, OR, WA, and AK
1 Provice: BC
Participating is easy:
- Decide which of the fungi below might be growing in a habitat that you are planning to visit.
- Print out the information in the links for the species you’re interested in and bring it along, or have it handy on your phone.
- If you think you’ve found one of the Rare 20, follow the instructions on the pamphlet for each species. Consider emailing us at westcoast_rare@fundis.org to let us know, and to ask any questions.
- We are also very interested in other fungi that you might find in these habitats. Consider joining our iNaturalist Project and sharing your observation there. Instructions are here, if you’re unsure how to do this.
- Please get a collecting permit if you’re thinking of visiting an area where collecting is restricted. More information can be found here.
