I used to belong to the Puget Sound Mycological Society (
www.psms.org), which is a very large and active organization which will help put you in contact with others who know a lot about mushrooms. They have frequent outings to help you get started in identifying the mushrooms you find and to meet others with similar interests. Google "mycological societies" to find other clubs that might be nearer to where you live or work.
There are lots of good books and field guides; you might check some out from your local library to see which ones you might want to buy for permanent reference.
On YouTube you can find a ton of good videos to help you get started, like those from
https://www.youtube.com/@YellowElanor. I'd recommend focusing on one particular mushroom species and view a lot of videos on that one mushroom species before moving on to another species. Don't start with the matsutake, as those are hard to find; as others wrote, maybe try looking for yellow chanterelles or morels (in the spring). Try to view videos that apply to our area, like ones from BC, WA or OR. For identification, I think videos are more useful than looking at photos in a field guide, as you get a better sense of size perspective, different shapes, colors and the environment in which they are found. There are mushroom identification apps for your phone, but I haven't found one that is particularly good, not like PlantNet for plants and flowers.
