Continental Mycoblitz 2019

Summer Mycoblitz

August 12 - 19, 2019
Registration will open in June. Begin applying for any local collecting permits you may need for this event.

2019 Online Foray

Welcome to the first online, continental-scale mushroom foray to take place on planet earth. Together with National Geographic and iNaturalist, we are working to document all of the macrofungi that exist in North America. A continent-wide online foray will be conducted from August 12 - 19, 2019. To participate just complete the online training and post your observations to the iNaturalist project during the foray week. Over 2,000 specimens from the event will be DNA sequenced. Your most interesting finds can help us to understand the mushrooms of North America. We look forward to discovering fungi with you!

What is a mycoblitz?

You may have heard of a "bioblitz" - an intense, and usually time limited survey of all of the organisms living in a given geographic area. A mycoblitz is a similar survey, but with the focus solely on fungi. Participants work to catalog as many species as they can from the survey area, during the survey time period. 

Bringing in 2,000+ new sequenced specimens (and counting....)

With the help of the foray partners, this event will bring over 2,000 new specimens - all DNA "barcoded" - into professional herbaria. Your organization can contribute by taking an active role in reviewing local specimens and/or contributing funds to DNA sequence more specimens from your particular region, or of your particular taxonomic group of interest.

During Foray Week


  1. Create new observations of mushrooms you encounter. This can be done through the iNaturalist mobile app or web interface. With each new observation, be sure to select the project for your event and whether you collected the specimen. The mobile app uploads the photos to the reports online.
    1. Take multiple photos of the mushrooms with your cell phone or camera. Take a nice image near ground level from the side, as well as an image of the top, the stem, and the spore bearing surface (this gills or pores on the underside of the cap).
    2. If you intend to save the specimen, take an image of the field data slip with the specimen. Please review the information here for more information. 
    3. Enter the field data slip number into the field in the mobile app.
  2. Collect the specimen. Store your field slip (or the portion with the number) with the specimen. 

Back at home, dry the specimens with a dehydrator or fan - Use the duplicate number at the bottom portion of the voucher slip to organize collections as they are being dried. Once they are cracker dry (usually 1-2 days) put the voucher slip and the specimen in a ziplock bag. Please put the iNaturalist number (in the URL of your observations) and the species name on the voucher slips. This will save us a huge amount of time once we receive the collections

Drying Tray

  • Mail in your dried specimens - Mail your specimens to our sorting facility. These specimens qualify for the "Library Rate" since they are specimens being mailed to a herbarium. All of the specimens that are collected as a part of this event will have their DNA "sequenced" or examined. We are likely to find multiple species that are new to science during this event. Your collections could be part of this.

Mail your specimens to:

Purdue Kriebel Herbarium
Lilly Hall of Life Sciences
915 West State St. Room G-447
West Lafayette, IN 47906

Post-event Tissue Collection

Tissue must be collected from all of the dried specimens so the DNA can be read or "sequenced." You will not be required to collect tissue as a part of the mycoblitz. This is the first step that occurs once your specimens arrive at the sorting facility.

Frequently Asked Questions

1. Do I have to fill out a data slip for each mushroom I see? No, only for specimens you are collecting. If you are simply taking an image of a mushroom to document it, you do not need to fill out a field data slip for it. Just take the pictures and create a report of the observation online.

2. Do I have to collect all of the specimens I see for them to count towards my totals? No. We do not need 100 collections of Turkey Tails (Trametes versicolor) or Dryad's Saddle (Polyporus squamosus). If you know the mushroom is common, a picture will suffice. Just be sure to take nice, close images from several angles. No need to collect it. But many mushrooms cannot be identified from a picture alone. Also, we cannot get DNA results from pictures. Saving the specimens allows us the potential to study them further.

3. Should I collect a mushroom if I cannot identify it?  Yes! Unidentified mushrooms are often the most interesting ones. 

4. What should I call the mushroom in the project if I do not know what it is? Just call it "Fungi" and someone will come along and identify it for you.

5. What if a mushroom is very large. Do I have to collect the whole thing? No, just collect a small portion, such as 1/4 of the cap. The best part to save is the top part with the gills/pores, rather than the stem.

6. Do I need the field data slips in order to participate? No, but it is strongly encouraged. It is tough to maintain organization without them. Specimens change significantly as they dry, so you will likely not be able to identify the mushroom later in the process without some type of identifying number attached to it. If you do not have field data slips (or run out of them) use the iNaturalist number to keep track of your collections.

7. What if I run out of field data slips?  You can download more slips online at any time.

8. What do I need to fill out on each field data slip? The requested minimum information to fill out is the date, your name as the collector (you can use initials), the site name, and whether or not you took field photos. The field for Foray ID is not being used for this event. The more information you are willing to save, the more valuable the report/specimen will be for science. Once your specimens are dry, please put the iNaturalist number for each collection on your voucher slips.

9. Do I need to smell and taste each mushroom? No, but this information is important for certain groups of mushrooms. These sections of the field data slip are optional, but encouraged. Also keep in mind that taste does not equal swallow. You can taste any mushroom without fear. Just gently chew a small bit of the mushroom and let it sit on your tongue for a few seconds to see if any specific taste starts to develop. Then spit the flesh out.

10. What are the numbers on the bottom of the field data slip for? The "Voucher Label for Drying" can be torn off and stored in your tackle box or basket with the specimen. This will allow you to keep the specimens organized with the pictures you take (be sure to take a picture of the field data slip with each specimen for the number and the scale bar on the side of the slip).  The "Tissue Label" is not something we will be using as a part of this project. Please keep it attached to the field data slip with the specimens you send in. This section will be attached to the tissue sample tube that will be used for looking at the DNA of your specimens.

11. Do I have to upload the photos using the mobile app? You have several options to get your images/reports onto iNaturalist. 1.) You can create reports using the mobile app in the field as you go along. If you do not have cell service, the app will store the individual reports until your phone is connected. 2.) You could take pictures in the field without using the mobile app, and upload individual reports later once you are back at home. (This is often the suggested method, as you don't have to fuss with as much in the field and can spend more time enjoying nature.) Finally, 3.) You could take images with a regular camera and upload individual reports on the iNaturalist website through your computer browser.

12. Does harvesting mushrooms hurt the environment? The short answer is no. It is misguided to think of harvesting mushrooms in the same terms as harvesting plants or other organisms. There have been multiple studies to explore this topic and none of found harvesting to have a negative impact on the mushrooms being harvested. Mushrooms are only the reproductive structure of the organism, like an apple on a tree. The main body of the organism lives under the ground or in the wood that you are harvesting the mushroom from. Walking through the woods off trail (ground compaction) is likely to have a greater impact on the environment than harvesting mushrooms. If harvesting large numbers of mushroom species had any detrimental impacts to the organism, we would be the first organization in like to discourage large-scale collecting.
