The seasonal pursuit of the morel mushroom, prized for its rarity, flavor & mystery

Educational Safety Note

Wild mushrooms can be toxic or deadly if misidentified.

When in doubt: don’t touch, don’t taste!

Spring in Wisconsin brings a brief and fascinating natural event: the appearance of the elusive morel mushroom (Morchella species), prized by chefs and studied closely by naturalists. 

When They Grow

Morels emerge only when conditions are just right. These mushrooms grow when daytime temperatures typically range from 50-60 degrees, with cooler nights in the 40s, and soil temperatures hovering near 50-60 degrees with balanced moisture. Long before thermometers, people used the old-timers’ guide, paying attention to nature’s cues for when it was the prime season to search for morels: oak leaves the size of a mouse’s ear, blooming dandelions or lilacs, and unfurling mayapples often signal the season. In Wisconsin, this window usually falls between late April and early June.

Though there are many species, morels are commonly grouped into three types: black morels, which appear first, followed by half-free (which appear 1-2 weeks later) and then yellow morels (after another 1-2 weeks).

What They Look Like

Morels are known for their honeycomb-like caps with deep pits and ridges. True morels are completely hollow when cut lengthwise, a key identification feature used by experts. They vary in color from cream and yellow to dark brown or nearly black and typically grow three to six inches tall. Their ability to blend into forest litter makes them easy to miss.

Where They Grow

These mushrooms are often found near dead or dying elm, ash, oak, and old apple trees, especially in sandy soils. They may also appear along rivers, in Great Lakes sand dunes, or in areas recently shaped by fire or flooding. This shows how fungi respond to environmental change.

How They are Used

Ethical foraging emphasizes respect for the ecosystem: taking only what can be used, leaving some mushrooms behind, and minimizing disturbance so future growth can continue.

In cooking, morels are valued for their nutty, earthy flavor. They must always be cooked before eating, as raw morels can cause illness. Simple preparation allows their unique taste to shine.

For many, the true reward of morel season isn’t just the mushroom itself, but the deeper connection it fosters with the land, the season, and the quiet knowledge that some natural wonders are fleeting and best appreciated with care.
