Shorter DNA Lab Day @ Mount Rainier Nature Center (28 Jun 2026)

Sun, 28 Jun 2026 14:00:00 GMT

Join us at Mount Rainier Nature Center at 10am to bring your mushroom samples or to ask questions about our process or anything fungi. Our experts are excited to see you! Mark your calendars! THIS IS A SPECIAL SHORTER VERSION TO ALLOW ATTENDANCE TO THE PICNIC!

Mount Rainier Nature Center is located at 4701 31st Place, Mount Rainier MD, 20712

If you are bringing samples to us, please ensure that the samples have been properly documented on iNaturalist, and that each of your samples has a unique iNaturalist observation number by the time of your arrival. Follow the process below to make your observation:

MAKING AN OBSERVATION

PHOTOGRAPH BEFORE DETACHING!

Take more than one picture
Show where the fungus is growing from (substrate)
- If attached to something living, identify as much as possible. Ex: conifer, deciduous, oak, american holly, etc.
Photograph the habit (growing alone, gregarious, in clusters, etc.)
Take a picture from the top

DETACH

Take a picture of the underside
Cut through the spore producing surface and notice if there are changes in color or secretion of latex. If so annotate and photograph
Add any smell or bruising you observe in the notes section

PREPARING SAMPLE FOR DNA EXTRACTION

Place the mushroom on a coffee filter, piece of paper, or wax bag
Write the voucher information: date of collection, location, name of collector, field ID (Russula, Bolete, Agaricus, etc) and iNaturalist observation number.
Place your sample inside its voucher bag in a dehydrator at 100° until it is dry as cardboard. The timing of his process will vary depending on the size of the mushroom.
- If you don’t have a dehydrator, you can place the mushroom in your oven using its lowest setting and leaving the door of the oven cracked with a clothespin. Check on this setting every hour to prevent burning or cooking the specimen.
Once the specimen has been dried, wait for it to cool to room temperature and place the voucher bag and the mushroom inside in a closed ziplock bag to prevent rehydration with humid air.

Once you have a dried specimen inside a bag labeled with your name, location, date of collection, iNaturalist observation number, and approximate ID, you are ready to bring the sample to us

In the link below you’ll find the slideshow used for the training on how to make observations and how to label your sample bag to serve as a voucher as well.

MAWDC Monthly Meeting - July VIRTUAL (07 Jul 2026)

Tue, 07 Jul 2026 23:00:00 GMT

Happy Semiquincentennial team fungi! For our July meeting we're going to change it up a bit, and learn about the geology of Camp Sequanota where our club has hosted its annual weekend foray for the past 40+ years. Located in the Laurel Highlands of Southwestern PA, Sequanota is a tremendous mushrooming location with a fascinating geologic history - and it's about time we collectively learned a bit more about the bedrock geology of this special place. Our lecturer will be Stephen Lindberg, a geology professor at the University of Pittsburgh, and after this talk, I predict future club mushroom forays will spend a lot more time looking at rocks.

Note that registration is open for Sequanota now. If you haven't already registered, what are you waiting for? Sequanota is a fantastic time!

We'll feature:

Club welcome and Save the Dates by Vice-President Allen Perper
Fungi in the News by Membership Chair, Tom Moore
ID table using the observations on our iNaturalist project, by Founder of George Mason University's Mycology Club, Jennifer Fieffer
Featured Presentation: Geology of the Laurel Highland by professor Stephen Lindberg, University of Pittsburgh

Camp Sequanota Mushroom Weekend (03 Sep 2026)

Thu, 03 Sep 2026 19:00:00 GMT

Registration closes August 16

To register, click the gray Register button that appears below the lodging options. (On your phone it should be just above the picture and on desktop it should be to the left of this text at the very bottom.)

Join MAW for a mushroom-filled weekend in Pennsylvania's Laurel Highlands. Our foray at Camp Sequanota has been an annual event for more than 40 years. It's a great opportunity to advance your mushroom knowledge and get to know other mushroom and nature enthusiasts.

Our guest mycologists are Shannon Nix and Todd Elliott.

Each day we will have mushroom walks at various locations and many workshops -- including mushroom cooking, mushroom ID for newbies, mushroom paper making, fungal felting, mushroom sculpting, medicinal mushrooms, and documenting mushroom diversity on iNat. In the evenings after dinner on Saturday and Sunday our guest mycologists will give presentations. Saturday concludes with a night walk, and Sunday evening wraps up with our fourth annual myco-costume/talent show (bring along a costume, a song, a poem, or a skit!)

Your registration includes 8 meals (Friday evening to Monday breakfast), all walks, workshops, and evening programs. (Thursday evening arrival is an extra add-on and includes Friday breakfast and lunch. Please add on for each guest too.)

Onsite accommodations options are basic motel-style rooms, summer camp style cabins, or camping. (Keep in mind nature is all around so it's possible there may be some small non-human guests in accommodations - staff will do their best to escort uninvited critters outside.) There are also a few different hotels within 30 minutes of the campus.

It takes many hands to put on this event so please consider volunteering some of your time to help with tasks such as cleaning foraged mushrooms and cleanup at the end of the event.

Note: guests are not permitted to bring dogs to Sequanota.
