Cain Foray cultivation workshop

2023 Cain Foray cultivation workshop

Join Storm Peschel, lead mycologist at Flow Mycological Sciences to prepare a bucket of Pleurotus ostreatus (Oyster Mushroom) to take home from the 2023 Cain Foray.

Sunday September 17th, 2023, 11:00 am at the Cain Foray

$60 per mushroom bucket. Registration fee includes bucket and all supplies.

Registration deadline: Monday, September 11th, 10:00pm

We will begin the workshop with a presentation to discuss the essentials of cultivating fungi, and some methods you can put into practice at home.

Then we will proceed outside where you will be provided with everything you need to inoculate a 5 gallon bucket with Oyster Mushroom mycelium. You will learn best practices, as well as some common misconceptions about growing mushrooms. There will be a chance to ask Storm any questions you might have.

You will take home your inoculated bucket to fruit at home. Many times one bucket will produce up to 3 flushes, or harvests, yielding a few pounds.

Growing mushrooms at home can be very easy. Join us at the mushroom cultivation workshop to learn more.


This workshop is limited to participants in the 2023 Cain Foray. There will be a maximum of 25 mushroom buckets available at the workshop. A minimum of 10 mushroom buckets must be registered in order for the workshop to be held (if the workshop is cancelled, you'll be refunded your workshop registration fee). Cancellations of workshop registrations by participants are subject to the Cain Foray cancellation policy.

Who can attend the Cain Foray?

The Cain Foray is an intermediate-level event which requires some knowledge about mycology and how to begin identifying species. In the past, new members and those who are new to species identification have found it difficult to participate in the Cain.

Participation at the 2023 Cain Foray is limited to members who are eligible to attend Introduction to Field Identification walks and Intermediate Field Identification forays.

See more about this change in the Who can Attend the Cain Foray? section of the registration page.

On-site accommodation charges paid separately

In previous years there was one single charge per person for on-site options at the Cain Foray, and this charge included accommodations.

For on-site options, the MST now charges only a registration fee per person. Participants choosing an on-site option will pay for their accommodations directly to Lumina Resort when they arrive and check in on September 15th.

Off-site participants do not need to pay the resort.

See more about this change in the Cain Foray Prices and Accommodations sections of the registration page.

Myco-Consortium talk June 15: Keith Seifert

As part of the MST's membership in the Myco-Consortium series of Zoom talks, MST members are invited to join the presentation on Thursday, June 15th at 7pm ET:

Three Microfungi that Changed the World

A talk by Keith Seifert
Thursday June 15th, 7pm ET

To celebrate the publication of "The Hidden Kingdom of Fungi," my recent book for general readers, I will present three stories in depth to show the profound effects of fungi (or "phungi") can have on human affairs. We will follow the path of the Great Potato Famine from its origins to the Irish diaspora of millions of victims to Canada and the USA. We will look at the discovery of penicillin and its impacts on World War II and conflicting concepts of intellectual property. Then we will look at some global aspects of wheat rust. These stories show that the impacts of fungi and fungal research extend far beyond the corridors of science.
