Could the Marshall Fire lead to a mushroom boom?
Hey Denver, it’s Paul.
I learned a very interesting fact recently that led me down a rabbit hole of wildfire science, ecology, and mycology – and I ended up learning quite a bit about Colorado along the way, too.
So, to quote my father-in-law’s current favorite joke, welcome to my TED talk.
A spore of intrigue
With psilocybin back in the news around the push for new regulations at the state level, I’ve been trying to learn more about mushrooms. And I was listening to a podcast about them when the host casually tossed off something fascinating: Morels, a highly sought-after and pricey variety of mushroom with a nutty, earthy flavor, are frequently found in the burn scars left by wildfires.
When I heard that, my mind started racing. Wouldn’t it be fun to grab a couple of microphones and go out into the Marshall Fire’s burn scar with a mushroom hunter and find a silver lining to a horrible tragedy?

But is it true?
“The short answer is YES.” That’s what Jon Sommer, former president of the Colorado Mycological Society, told me when I emailed him about this.
He also told me that there is a “very strong” mushroom hunting community here in Colorado. His group alone has 850 active members, with nearly 22,000 more on Facebook, so if I wanted to go out to a burn scar and hunt for mushrooms, that could probably be arranged.
Another local mushroom hunter, Orion Aon of Forage Colorado, went into more detail: “Morels that grow in burn scars are generally called ‘burn morels.’ Most often, these are the morels you would see in fancy grocery stores and at restaurants,” Aon wrote. “They are technically part of the group known as ‘black morels,’ those morels that have a darker colored cap.”
Why does this happen?
“We still don’t fully understand the morel-wildfire interaction and why they fruit so heavily after a fire,” Aon wrote. “But it’s theorized that it could be a result of the burst of nutrients sent into the soil from the ash and dying plant materials, or because their host trees are now dead they have to move using spores to find a new living forest. Either way, the first year after a burn in a western forest it’s very likely that the morels will fruit.”
Wait a minute. This only happens in forests?
Unfortunately, yes. Both Aon and Sommer told me the Marshall Fire’s burn scar is unlikely to produce any morels because there weren’t enough of the right kind of trees in those parts of Louisville, Superior, and unincorporated Boulder County.
Sommer explained that morel growth depends on three main factors:
- Moisture levels in the spring and summer after the fire
- The intensity of the fire. Apparently if a fire burns too hot it can sterilize the soil
- Tree variety. Some types, like conifers, are more conducive to morel growth
“A ‘good’ burn scar for morels would be one that was forested before the fire, and the more trees the better in most cases,” according to Aon. “Morels, and many other mushrooms, have mycorrhizal relationships with trees. Essentially, a symbiotic sharing of resources. Without the trees you won’t have the mycelium and thus won’t have the mushrooms.”
So if you’re willing to drive…
“The 2020 fires – Cameron, East Troublesome, etc. – were very good for morels last year, and should fruit again this year, though in lesser quantities,” according to Aon.
But competition for those precious morels is likely to be pretty hot again this year. “Because morels are very difficult to cultivate,” Aon wrote, “commercial pickers flock to last year’s burns to pick morels and sell them to suppliers, restaurants, etc.”
What’s an aspiring mushroom hunter to do?
Number one, don’t just go out looking for any old mushroom to eat. Everyone agrees that’s a surefire recipe for stomach pain, if not worse.
If you’re looking for inspiration before the mushroom season starts in April, the Colorado Mycological Society hosts a new guest speaker each month at the Denver Botanic Gardens between March and October. You can learn more about the CMS and see their full schedule here. Or join that Facebook group I mentioned here.
Aon Orion offers a variety of online and in-person classes ranging from a $20 introductory zoom session to a $500 full-day mushroom hunting expedition for you and four of your closest friends.

OTHER ODDS AND ENDS
🏈 The Broncos are officially for sale: CEO Joe Ellis announced yesterday that former Broncos owner Pat Bowlen’s many children were not able to reach an agreement about which, if any, of them should take over control of the team. So the Broncos are heading to the open market. Will Peyton Manning put together an ownership group to bid? How about John Elway? Jay-Z? Jeff Bezos?
👉 What you can do: Catch up on the whole Bowlen family drama and what it means for Denver in Bree’s interview with Ryan Koenigsberg and Zac Stevens of the DNVR Broncos Podcast from last month.
🏚️ Bad news for homeowners affected by the Marshall Fire: It’s going to take twice as much time to rebuild homes lost in the Marshall Fire, according to Colorado State University professor Paul Goodrum. It typically takes six to nine months, but between supply chain issues and the ongoing shortage of skilled laborers, Goodrum says he’s heard estimates as long as two years.
📺 State lawmakers propose a fix to get the Avs, Nuggets back on TV: Speaker of the Colorado House of Representatives Alec Garnett introduced a bill he says would “force” Comcast and Stan Kroenke’s Altitude Sports and Entertainment into arbitration to resolve their years-long dispute. Comcast is by far the region’s most popular cable provider, Altitude holds exclusive rights to the Nuggets and Avs broadcasts, and both want to squeeze every last penny out of the other. “I just want to watch TV and these big rich guys aren’t allowing me to do it,” Garnett said on the Get More Smarter Podcast this week. “And it’s really, really making me angry.”
🌨️ It’s cold and it’s gonna get colder: If you’re reading this anywhere near Denver, there’s likely a blanket of snow outside your window. And get this: It’s not supposed to get back up above freezing until Friday! Up to three more inches are expected today, according to the National Weather Service.
🎧 LISTEN: Denver’s Mask Mandate is Lifting. So Is This Thing Over Yet?: Alongside Adams and Arapahoe counties, Denver is allowing its indoor mask mandate to expire this week. Mayor Hancock says we’re still in the middle of a public health crisis, though, so we called up Dr. Jonathan Samet, an epidemiologist and the dean of the Colorado School of Public Health. Bree asked him what we can expect from this new phase of the pandemic, how he’s adjusting his behavior, and why Mayor Hancock likely thought now is the time to go “mask off.”
