The Study of Mushrooms Taught Through Our Online Classes

The study of mushrooms is typically referred to as Mycology. More broadly, mycology is the scientific study of all fungi regardless of if they create a mushroom or not.

Check out our Home Mushroom Growers Class, our Commercial Mushroom Cultivation Course, and our Online Medicinal Mushroom Course!

About 90% of fungi never create a mushroom, which is the fruiting body of some fungi that can be seen by eye and picked by hand. This page contains several courses to begin and dive deeper into the study of mushrooms. We will cover foraging, basic fungal information, growing mushrooms for the backyard, and growing mushrooms as a business. The study of mushrooms as medicine is a growing field that needs a lot of attention. More scientific trials and clear labeling of medicinal mushroom supplements is essential for consumers and businesses using medicinal mushrooms. Our online courses are designed to help you understand the process of growing mushrooms at various scales, in addition to the healthful benefits of consuming mushrooms.

The different ways to explore the Study of Mushrooms:

There is so much fear around mushrooms that is unnecessary and undeserving. Mushrooms have so much to offer us humans in many different facets. That’s why we are offering online course to get you more familiar and friendly with mushrooms and the fungal kingdom. Some of our offerings:

About the instructor:

Willie Crosby has been engaged in the study of mushrooms for the last 6 years. He started Fungi Ally in the basement of his house and grew out to a 3,000 square foot warehouse with 5 tractor trailers attached a total of 5000 square feet. Fungi Ally was growing 500 pounds of mushrooms a week in September of 2018. That aspect of the business was sold in October of 2018 and now Fungi Ally focuses on education and spawn production. Willie has taught online for Cornell University and Umass amherst for the last 3 years. Willie taught in person at Umass for 4 years. Willie has received 5 SARE grants and 6 other grants over the last 5 years for growing mushrooms and educating the public about mushrooms. Just this year willie published two guidebooks which you can download for free at on our website.

“Working with Willie was a breath of fresh air. He quickly understood our goals, and provided recommendations that reflected our values and complemented our resources. With his help we were able to get to the heart of what matters, and devised a cultivation plan and infrastructure that will be efficient to operate, in line with our needs as a growing farm. Willie’s insight and support helped to build our confidence to grow mushrooms with new methods, and provided practical information on how to start small and grow over time.” –Alanna, farm manager in upstate New York.
