Naturalist's Corner - Fungi Fun

A wreath of turkey tails around a stump

Wow! The late summer and early fall woods have been a wonderland of interesting fungi. While the flowers of the prairies and forests are fading, the mushrooms are still popping.

We often hunt for mushrooms for tasty eating. Who can resist a morel, chicken of the woods, chanterelle or lobster mushroom? But there is much to be said for simply delighting in and learning to identify the mycelium network's endless parade of interesting fungal fruit.  

Fruit? Yes, fruit.

Mushrooms and fungi are the fruiting bodies of the vast, intricate mycelium network that stretches underground, often for miles. Mushrooms use enzymes to break down organic material rather than photosynthesis. They are the great decomposers of the earth. The material that is broken down eventually becomes soil. We see that decomposition work in every branch or tree trunk covered in fungi that we pass along the trail. And, if we stay alert on the sides of the trails we hike, there are many delightful fungi to catch the eye.

If you have the opportunity, I highly recommend going on a guided hike or two with mushroom experts. They provide great tips on finding and identifying both edible and non-edible fungi. As someone new to mushroom identification, I found these learning experiences really helpful as my eyes got more attuned to fungi finding. Plus I'm lucky to have lots of hiking buddies who share my delight - and much sharper eyes than mine!

As a newbie, I often see a mushroom on the trails that I can't identify. I take photos from different angles and then head home to work on more accurately identifying the fungi. Apps like Picture Mushroom, Shroom ID, Shroomify can help to get a first general ID but can be pricey.  Seek can sometimes come in handy but often can only do a generalized identification.

So I start my real study with Teresa Marrone and Kathy Yerich's field guide, Mushrooms of the Upper Midwest. This guide is small enough to carry in a back pack but I am often hiking at pace and don't have the time to linger. At home, I can take my time to compare my photos and their descriptions to come up with an identification. 

Below are a few of my favorite fungi pictures from the last several months. I hope you keep your eye out for the next few weeks while you're leaf-peeping and see what you can find!

Lansing Bridge Closure Update

If you are a hiker who often goes between Lansing IA and the Wisconsin side of the river, you know how important the Black Hawk bridge is. Please consider giving the river towns along both sides of the river some extra spending love over the next year and a half to help them weather what could be critical financial downturns. Here is the latest news release on the Lansing Iowa Bridge closure timing and plans:

Iowa 9/WIS 82 Mississippi River Crossing Project Announces Bridge Closure Date and Plans for Car Ferry Service

LANSING, Iowa – Oct. 7, 2025

The Iowa and Wisconsin Departments of Transportation are proceeding with plans to close the existing Iowa 9/WIS 82 Mississippi River bridge between Lansing, Iowa, and Crawford County, Wis., as construction on a new bridge continues. 

• The existing bridge (also known as the Black Hawk Bridge), will close to traffic at approximately 7 a.m. on Monday, Oct. 20. 

• Iowa DOT and WisDOT will initiate a free car ferry starting in early November to provide alternative service until the new bridge is projected to open in spring of 2027. 

The car ferry service is moving ahead after federal and state government agencies issued permits and provided other environmental clearances.

“We are very pleased that federal and state agencies, including the U.S. Fish & Wildlife Service and the city of Lansing, could work together and quickly approve the necessary steps to allow  us to provide this critical service,” stated Iowa DOT Director Scott Marler. “These approvals will allow us to install the infrastructure needed for a car ferry to keep our communities connected when the old bridge needs to be closed.”

The free car ferry will provide an alternative way for vehicles to cross the river. A new bridge is  being constructed alongside the existing bridge. Iowa DOT, WisDOT, and the contractor have determined that future construction stages on the new bridge pose a risk to the safety of the existing bridge. Once the existing bridge closes on Oct. 20, crews will start to demolish and remove the old structure so construction on the new bridge can meet the planned 2027 opening.

“We are providing a new and modern structure that stretches across a beautiful and scenic stretch of the Mississippi River,” noted Wisconsin DOT Secretary Kristina Boardman. “The state 

and federal approvals confirm that we can build the bridge and offer the car ferry service while still maintaining the natural environment that makes this region so special.”

The project will need to install car ferry landings on both sides of the river. Ferry landing construction is already underway, and the exact start date for the ferry will be announced as the work progresses. On the Iowa side, the landing will be located at the Lansing marina, while the ferry will land on the Wisconsin side just south of the new bridge and adjacent to the construction staging area. Planned site improvements including installation of ferry docks, vehicle queuing areas, directional and informational signs, variable message signs, lights, and other features. On the Iowa side, improvements to railroad crossings at the entrance and exit points of the marina have been completed. (A conceptual map is attached to this release.)

In addition to the car ferry, there will be marked detour routes when the bridge closes. The nearest highway bridge is approximately 30 miles south at U.S. 18 connecting Marquette, Iowa, to Prairie du Chien, Wis. The car ferry will serve two-axle vehicles, motorcycles, bicycles, and pedestrians, but will not be able to accommodate trucks, buses, trailers, or other large vehicles.

The bridge closure date and car ferry service date will continue to be announced through the  project website, the project Facebook page, local media, on digital message signs on either end of the bridge, and through 511ia.org.

The Iowa DOT and WisDOT project teams are also communicating closely with government officials and other stakeholders in the affected communities. The project website will soon feature an instruction and FAQ section about the car ferry service to help local residents prepare for that option.

I Spy on the Trails - September 2025

Foggy morning start on the bluffside

September is always a month of transitions. The trees continue to shut down their  chlorophyll production and "gray" out more. Their full color change in the Driftless has just begun to hint at the coming colors. 

Mornings and evenings are dewy and often foggy.  It's not unusual to hear coyotes barking and baying and barred owl calls are more prominent.  

Crickets and grasshoppers dominate the sound scape. Songbirds continue their migration in massive numbers through our area which leaves the mornings to our more permanent resident winter birds. 

Big bluestem seeds

The flowers that brightened our hikes have been slowly exhausting their blooms throughout the month. Many forbs that filled the trails at the beginning of the month are now done flowering.  A few late asters and the late goldenrods remain. Grasses have set seed as well. The pollinators are few and far between as the forbs go to seed.

Mushrooms and other fungi love the cool damp of September and the mycelium network is fruiting everywhere. They have fascinated me throughout the month and given me plenty of time to learn them a little better. A trip up to Minnesota's Arrowhead to the North Shore and Ely introduced me to a number of new-to-me mushrooms and fungi. I love their variety. Many are toxic so I just admire them unless I know what I'm doing - and then, num, chicken of the woods!

Guide Nancy introduced me to
Kellogg Weaver Dunes

Weatherwise, our month began with a bit of a nip and then settled into some beautiful 70's weather which then morphed into some sticky humid mid-80s. The second half of the month saw temperatures moderate into a more normal September pattern before turning up the heat to usher the month out. We had a bit of rain here and there during the month before a giant dump of 2-3" in the last full week. Climate change makes for whiplash weather.

Sagittarius reflected in
Burntside Lake, Ely

With the autumn equinox now here, our skies darken earlier and on dry, haze-free nights, the star-gazing has been awesome. Orion and Sagittarius are rising, a sure sign of advancing fall and coming winter.  The dark skies up in Ely revealed the Milky Way as a bright slash across the sky - a view I miss, living so close to city lights.

It was a slow hiking month after I pulled something in my knee and my doctor suggested I give it a three week rest to see if it would bounce back. I chose gentle, flatter ambling walks and wandered along the edges of woods and prairies while we traveled to catch sight of what I could. Amazingly enough, there was plenty to see even though the hikes were short.

I was very excited to have this blog featured in an article in the Mississippi Valley Conservancy newsletter and website. Big thanks go out to Karen Solverson and Kelly Sultzbach for sharing the story of the blog!

At Frontenac State Park
Nature School

I had the opportunity to go on a couple of Nature School Classrooms guided hikes before my knee conked out on me. The hikes were incredibly inspiring and rich in information. These Nature School opportunities contribute to my annual training hours to maintain my MN Master Naturalist volunteer certification but anyone would benefit. 

They included: 

Prairie Walk/Talk - Sea of Grass authors Dave Hagar and Josephine Marcotty hiking prairie trails and sharing their research and writing on prairies and their importance. Frontenac (MN) State Park

Damsel and Dragonflies - Jeff Fischer of the MN Dragonfly Society presented on damsel and dragonflies, delving into the different types of this fascinating onodata insects and their lifecycle before we went into the field to try to capture some (sorry too cold for them!). Frontenac (MN) State Park

There are still plenty of great guided hikes and learning and volunteer opportunities coming up in October. I hope I see you on one.

See you on the trails!

The "I Spy on the Trails" column is a phenology (the study of seasonal changes in plants and animals) journal to chronicle year-round the weather, plant life and wildlife I observe while hiking. It is very useful in helping me compare observations from year-to-year. The column is published monthly from September through April and then twice-a-month from May through August when warm weather brings the natural world back to vibrant life.
