Resources and Faqs

This list of our favorite resources and answers to some of our most frequently asked questions will develop over time. Feel free to mention your favorite mycological resources in the comments.


While more difficult to keep updated with the very latest research, physical books are hard to beat for depth of information and access to reference when needed.

Field Guides/References

North American Mushrooms: A Field Guide to Edible and Inedible Fungi by Orson Miller and Hope Miller: This is the field guide we recommend having on hand for our mushroom identification classes. Orson and Hope Miller were longtime members of SIMA and made invaluable contributions to the field of mycology the world over.

Mushrooms of the Pacific Northwest by Steve Trudell and Joe Ammirati: Steve Trudell has been our foray mycologist several times.

Mushrooms Demystified by David Arora: A classic and comprehensive tome with identification keys and plenty of additional information.

All That the Rain Promises and More: A Hip Pocket Guide to Western Mushrooms by David Arora; A bite-sized version of his larger work you can fit in your pocket. Focuses on some of the most frequent macro fungi you’re likely to see in our area.

Other Mushroom Books

Entangled Life: How Fungi Make Our Worlds, Change Our Minds & Shape Our Futures by Merlin Sheldrake


Websites are more likely to be updated on a regular basis and include links to other related information, but they’re harder to curl up with on a rainy day.

Mycology Clubs and Associations

The North American Mycological Association: Our parent organization with information about the national foray event and links to individual clubs.

The North Idaho Mycological Association: (NIMA) Our sibling to the north.

Mushroom Identification and Cataloging

Mushroom Observer: A volunteer-run database of mushroom observations and identification. You can sort by location, observer, species and more.

Mushroom Expert: A site maintained by Michael Kuo. Great pictures and keys.

    1. Greetings Wendy!
      I didn’t receive a notification of your comment and so just now saw it as I was doing some work on the site. I will be sending you a message from our idahomushroom club email very soon.

  1. Hello everyone,

    I live and mushroom hunt in Central Pennsylvania. I’ve yet to find king boletes here in PA. Other people claim to find them, I have not. I’m considering a trip to Idaho for some king hunting, etc. What month of the year do king’s like to pop, September/October? Also, what is there tree association there? Here I have heard they’re found under spruce, but I haven’t looked for them considering they’re rare to find. I hunt morel, black trumpet, chanterelle, grifola, etc. Any info would be greatly appreciated.


    1. Hi Darren! It appears we’re still having issues with our website failing to notify us of new message requests – sorry it has taken so long to get to your comment. Love that you’re planning to make a visit!

      With Idaho covering so many degrees of latitude, the season really depends on where you’re hoping to visit. Central/southern Idaho is very different from north Idaho, which tends to be much more like the Pacific Northwest climate. In the central Idaho mountains (sort of Riggins south to Cascade), we are in the middle of our short “spring king” season right now (early June to early July). If you move up and down in elevation you can find some throughout the summer, but definitely fewer in number. And then, yes, August/September/October when we begin to get fall rains is when they can come on really strong. I often find them most strongly associated with our Pine forests, but also have good luck in mixed-conifer areas. That isn’t a great deal of help, I know, but the areas where they can be found in Idaho are vast. Lots of public land to hunt upon!

      SIMA has our fall foray tentatively planned for October 1-3 in McCall, Idaho. It really depends on what the weather decides to do, but that can be a great time to find Boletes. There are also usually Cantharellus, Hydnum, Polyozellus. Hericium and many others. No Grifola unfortunately, but perhaps we could arrange a trade if you come out! 😉


  2. I’m interested in joining and I was told by Robert Spence to come here to request to be put on the mailing list.

  3. Hello,
    I am in SE Idaho, Rupert, ID would you please put me on your newsletter list.
    Are there meetings in Rupert/Burley or Twin Falls?
    I know nothing but somehow I am connected to shrooms.

    1. Hi Aiden,
      (I removed your email address so you don’t get [email protected]), and yes, I will put you on our newsletter list today. We meet in the Boise area, but I sure hear from a lot of people in the Twin Falls and Idaho Falls area lately! There is probably enough interest to start a group of your own if you could get together (there are several others in the comments if you look through them). I’d be happy to try to connect you to resources if that’s something you’re interested in. All it takes is a few enthusiasts to get together to start a club…that and time hunting. Mushrooms are a fascinating hobby!


  4. Hello there, my name is Morgan and I live in Twin Falls and would love to join this good and go on some foraging trips to learn what edible mushrooms we have here.

    My email: [withheld]


    1. Hi Morgan,

      I will send you an email with membership info. (I removed your email address from the comment so you don’t get [email protected] At this time we don’t have any forays planned in that area but I’ve been hearing from quite a few people over there so I’ll try to get you all in touch if you like. Maybe we could plan a meet-up.

  5. I am from Central PA and I came to Idaho this year for some great Morrel hunting! I love Idaho, wish I could get my wife to move there.

    Anyway, talking to other mushroomers in Idaho, no one seemed to understand me asking them when the large yellow morels come up? We were finding lots of blacks, but here in PA the larger yellow morels come up a few weeks after the blacks. Does Idaho have both black and yellow morels?

    Thanks you and blessing to you all.

    Please reply to [withheld]

    1. Hi Ray! We DO have “yellow” or “blonde” morels, but they show up in different places and at different times. Most likely different species. Along the lower-elevation river bottoms, like in the Treasure Valley, we can get M. americana showing up in mid-April into very early May. A few odd giant blondes can be found later in May some years. I have not seen those higher up in places like McCall. Our mountain species in central and southern Idaho are usually the “burn” morels and other so-called “naturals”. M. snyderi and M. tomentosa among others. You might look at M. tridentina and see if that corresponds to the “yellow” morels you’re thinking of, or if they are more like M. americana. M. tridentina comes up after our mountain blacks in my experience. It may be different up in northern Idaho too – they have a rather different climate than we do so it depends where you were. Glad you got to enjoy some Idaho hunting! I would love to come to PA for some mushroom hunting someday. Particularly Grifola frondosa!
