Mushrooms create mini-windstorms to spread spores

Releases of water vapor create convective movements

FRISCO — We’ve all heard of microclimates, where topography and other factors can affect weather on a very local level. But new research suggests that mushrooms take that concept to whole new level, creating their own mini-windstorms to help spread spores.

Biologists have long thought that the spores produced by a mushroom’s cap simply drop into the wind and blow away. But observers have noted that spores disperse even when the air is still. It took a detailed study by fluid dynamics researchers find the answer.

Using high-speed videography and mathematical modeling of spore dispersal in commercially grown oyster and Shiitake mushrooms, they found that the fungi created their wind by releasing water vapor. The vapor cools the air locally, and this creates convective cells that move the air around in the mushroom’s vicinity. Continue reading

Forest comes alive with fungi

FRISCO —It’s pretty hard to walk anywhere in local forests and fields without stumbling across a patch of mushrooms. Lingering monsoon rains and relatively warm temperatures have fostered an incredible diversity of fungi this year.In many years, we’ve had at least a couple of frosts by this time of year, which generally means the end of the season for all but the heartiest species. During a short walk near Officers Gulch Thursday I spotted more than 30 species in less than 15 minutes before losing count, and there are at least a half-dozen species growing in the landscaped areas around our Frisco townhome complex. Get out and enjoy it now, because it may well be several years before we have another season like this one. Continue reading

Whew!

Here’s how the day started in Summit County, with a little help from Instagram.

FRISCO — Labor Day weekend got off to a good, if somewhat soggy, start, with visitors from the Front Range and around the country thronging the high country for one last summer weekend, even as ski resorts started ramping up sales efforts for season passes. But the lingering monsoon has kept things pretty warm. The moist air acts like a blanket; so far we haven’t had those first few crisp nights that often do in late August, but nobody is complaining.

Sunday magazine: Mushroom mania in Colorado

From tasty meals to myco-remediation …

FRISCO — Fungi fanatics are calling it one of the best seasons in recent memory, as steady summer rains spurred a bumper crop of stinky squid, shaggy ink cap and purple slime mushrooms, not to mention delectables like porcini and chanterelles.

This past weekend, a handful of Colorado towns held festivals to celebrate mushrooms in all their diverse glory — if we’re all connected intellectually via the electronic web, then we’re probably also connected biologically, and fungi are one of the key threads that holds the web of life together.

In Telluride, amidst the good-natured fun of mushroom-themed parades and cook-fests, scientists discussed the latest research on myco-remediation. There’s promise that known — along with as-yet unstudied species — that fungi could help with a wide range of environmental and human health issues.

The mushroom festival maintained a lively social media feed on Twitter, sharing images like this:

In some situations, fungi could help clean up lead contamination, and Forest Service scientists are trying to improve restoration of dwindling whitebark pine forests with fungal applications.

In Scandinavia, forest researchers have discovered that fungi play a greater role in the carbon cycle than previously understood, and there are also concerns that a warmer and wetter future world could spur the growth of forest-killing fungi. Continue reading

Berries-n-shrooms!

Wild strawberry Colorado

Wild strawberries are a special forest (and meadow) treat in Colorado.

FRISCO — Even a short walk in the woods can be rewarding these days, what with wild (and delicious) edible mushrooms popping up all over, along with a veritable feast of berries, which always do much better in wet years, especially when the rains are followed by some warm and sunny days. All this on a day that also brought the first snow to the Colorado high country, although we probably shouldn’t even think of it as the first snow, since it’s only been a few short weeks since the last time frozen white stuff fell from the sky. But for some reason, in August, it does feel like the first snow of the new season, while a July dusting (also not unheard of) seems to belong with the past winter. In any case, get out and enjoy summer’s bounty now! Continue reading

A break from winter

FRISCO — After writing a story about the importance of biodiversity, I went back to a folder from last July to look over the mushroom images I shot during a few forest visits in Austria. The biodiversity story got me thinking about how some of the mushrooms I found in Europe were completely different from anything I’ve ever seen in the West, while a few other species were almost identical. Why is it that some species are common on both sides of the Atlantic, while others are more specialized to either the Rockies or the forests of Central Europe? I’m not really sure, but I think it has something to do with the plant communities. Since some fungi are in specialized symbiotic relationships with certain species of shrubs and trees, they may not be able to grow if those plants are present. Maintaining healthy forests requires making sure that all the constituent elements of the ecosystem are there, and in Colorado, we know so little about the fungi that are a key part of the ecology that we may just be stumbling in the dark.

Friday Fotos: Secrets!

Shhhhh — don’t tell!

Dylan shreds a “secret” powder stash at Vali, Colorado, a few years ago.

FRISCO — It’s hard to keep something a secret when you post pictures of it, but that’s part of the fun and charm of this week’s edition of the weekly #FriFotos Twitter chat, one of the coolest social media events on the web. As a writer and photographer, I’m constantly torn between sharing the amazing places and stories I discover in the course of reporting and keeping them as private secrets, In some cases, people ask me specifically to not give away certain locations. In other situations, it’s part of my job to uncover dirty little (or big) secrets held by big corporations or even the government. For FriFotos, I’ll steer away from the muckraking and stick with sharing some of the best secrets from around my home stomping grounds in Summit County, Colorado and a few other spots.

Got a secret you’r itching to share? Upload your pic, tag it with #FriFotos and join the conversation. Continue reading

Mushrooms are popping!

SUMMIT COUNTY — Tis the season — for fungi, that is, as monsoon moisture has help spur a good crop of wild forest mushrooms. While some people see them as the equivalent of low-life slugs, mushrooms are actually a vital and little understood component of forest ecosystems. Along with helping to break down dead leaves, grass and branches, the underground part of the fungal organisms interact with the roots of trees and other plants, helping to foster a nutrient cycle and maintaining a chemical balance in the forest floor.

Late summer

Midday light can be harsh, but in this case, the sun shining top-dpwn helped by backlighting the gills of this forest mushroom. I used an Instagram filter with this iPhone photo to enhance the colors.

SUMMIT COUNTY — The mushrooms are popping and generous August rains have helped spur a late surge of wildflowers in the area … meanwhile, haze from distant wildfires help filter and soften the light — all in all, good conditions for photography in the high country. Continue reading

Sun, snow, clouds, water …

Cloud reflections.

SUMMIT COUNTY — Taking photos of pleasing natural patterns is like a meditation of sorts. Sometimes you have to just sit and let everything fall away before the image comes to you. It could be in a forest, sitting on a stump, beside a pond or stream or even just in the backyard. Other times, it’s fun to go out and actively look for, and even shape the scenes by finding just the right spot, or by trying different focal lengths. Continue reading
