Mid-Atlantic mushroom foragers collect 160 species for food, medicine, art and science
Pennsylvania’s rich tapestry of wild mushrooms, both edible and poisonous, has captured the attention of foragers, especially during the COVID-19 pandemic. As many sought solace in nature, one researcher, inspired by a remote ecology and anthropology course at Penn State, turned to mushroom foraging in the central region of the state. This newfound interest sparked a collaborative project with Eric Burkhart, focusing on understanding the diversity and practices surrounding mushroom harvesting in Pennsylvania. Despite the long-standing tradition of foraging in the mid-Atlantic, formal studies on the topic were sparse, prompting their initiative to survey local harvesters about their experiences and knowledge.
Between 2022 and 2023, Wrobleski and Burkhart gathered insights from over 800 mushroom harvesters, uncovering that a staggering 160 species are foraged in Pennsylvania. The most popular varieties included morels and chicken of the woods, each favored by 13% of respondents, while chanterelles followed closely at 10%. The survey revealed that foragers primarily collect mushrooms for culinary and medicinal purposes, with many also engaging in artistic pursuits like photography and natural dye creation. Interestingly, while a commercial wild mushroom industry thrives in the region, the majority of harvesters prefer to share their finds with friends and family rather than selling them.
The study also highlighted the growing trend of using technology in mushroom foraging, with many new harvesters relying on the internet, family, and guidebooks for education. Apps like iNaturalist have gained popularity, allowing users to document their finds and contribute to community science projects that track biodiversity. As the foraging community expands and shares knowledge through social media, there’s a significant opportunity for collaboration between amateur foragers and researchers. Such partnerships could enhance understanding of fungal populations and their ecological impact, paving the way for sustainable practices and further exploration in the field of mycology.

Like many mushroom harvesters, I got interested in foraging for fungi during the COVID-19 pandemic.
I had been preparing for a summer of field work studying foraged desert plants in a remote part of Australia when the pandemic hit, and my travel plans were abruptly frozen. It was March, right before morel mushrooms emerge in central Pennsylvania.
I wasn’t doing a lot other than going on long hikes and taking classes remotely at Penn State for my
doctoral degree in ecology and anthropology
. One of the classes was an agroforestry class with
Eric Burkhart
. We studied how agriculture and forests benefit people and the environment.
These two things eventually led to a
yearslong project on mushroom harvesting
in our region.
Why people forage
Foragers have been harvesting wild mushrooms in what is now Pennsylvania and the rest of the U.S. mid-Atlantic region
for generations
, but the extent and specifics of the practice in the region had not been formally studied.
In 2021, Burkhart and I decided that we wanted to better understand the variety of wild mushroom species that Pennsylvania harvesters collect and what they use them for.
We conducted a series of surveys in 2022 and 2023 that revealed a
wide variety of fungi are foraged in the region
– though morels, chicken of the woods and chanterelles are most common. We also learned that harvesters use the mushrooms primarily for food and medicinal purposes, and that foragers create communities that share knowledge. These community based projects often use social media tools as a way for mushroom harvesters to share pictures, notes and even the results of DNA sequences.
Our findings were published in the journal Economic Botany in October 2025.
160 species
Having spent a year building connections with local mushroom harvesters, starting in central Pennsylvania, including members of
mushroom clubs
and
mycological associations
, we recruited a diverse group of harvesters from around the mid-Atlantic. We also used mushroom festivals, social media and word of mouth to get the word out.
We asked harvesters about their favorite mushrooms, common harvesting practices, resources they used while harvesting and any sustainability practices.
Over 800 harvesters responded to the survey and reported that, collectively, they foraged 160 species of wild mushrooms. Morels and chicken of the woods were the two most popular, as each were reported by 13% of respondents. About 10% of respondents reported collecting chanterelles. Other popular species were hen of the woods, oysters, lion’s mane, black trumpet, honey mushroom, turkey tail, bolete, reishi, puffball, chaga, shrimp of the woods and Dryad’s saddle, which is also known as the pheasant’s back mushroom.
Harvesters reported a variety of reasons for collecting mushrooms. Many collected morels and chanterelle to eat, and species such as turkey tail, reishi and chaga for medicinal purposes. Art was another common reason cited for foraging, with photography being the most popular use, followed by using mushrooms to create natural dyes and pigments.
Other survey respondents said they foraged to feel more connected to nature. And while there is a thriving commercial wild mushroom industry in the region, we found that only a small minority of harvesters sell their mushrooms. Most people reported giving their mushrooms to friends, neighbors and family.

Citizen science
We also wanted to better understand which resources mushroom harvesters turn to in order to learn more about this hobby. We asked all the harvesters what they used as a resource when they were first learning to hunt for mushrooms. A quarter of new harvesters said they used the “the internet,” followed by “family,” at 24%, and then guide books, at 20%.
Based on the survey responses, we also learned that mushroom-identification phone apps are growing in popularity, especially among new harvesters. For example, a commonly used app called
iNaturalist
allows harvesters to upload a few pictures of their find – one of the mushroom in its habitat, another of the underside of the cap, and a third of the entire mushroom. From there, other community members can comment and help with identification.
Harvesters also use these apps to contribute to
community science projects
that document biodiversity.
Some mushrooms are poisonous if eaten, which is part of why harvesters are so careful with their identification. When learning a new mushroom species, it’s important to look into multiple sources to make sure what you’re harvesting is safe to eat.
With more harvesters documenting their findings on social media and sharing information about fungal biodiversity in the region, there is much to glean and learn about the diverse world of mushrooms in the mid-Atlantic. We believe that deeper collaboration between community groups and researchers at universities and other institutions is an opportunity for scientific growth within the field of mycology. This collaboration can support long-term tracking of fungal populations and any impact that harvesters might have on them.
