Illinois Mycological Association

Celebrating 53 Years! 1973-2026

About UsHow to Join

The Illinois Mycological Association is a group of fungal enthusiasts that meets frequently to learn about fungi through talks presented by experts, and to look for, identify and document wild fungi. We host monthly meetings with invited speakers, mycologist-led surveys to gather and document fungi, and an annual show at the Chicago Botanic Garden.

We welcome you to attend and learn more about fungi and the wild mushrooms of Illinois and the Chicago region.

March Mushroom of the Month:
Tubaria furfuracea // Scurfy Twiglet

This small but charming little brown mushroom (LBM) is much more common than most people realize—because they just don't notice them! This tiny saprobic fungus fruits on wood chips, twigs, and woody debris, often appearing in areas like landscaped gardens, mulched flower beds, and park trails. The "furfuracea" in its name means "scurfy" or "covered with scales," referring to the fine, almost downy coating on its cap when young.

What makes this mushroom particularly interesting (and there’s not much) is its ability to fruit prolifically in urban environments where wood chip mulch is abundant, and that it also tends to start fruiting in late winter before most of the other macro fungi start popping up. While many fungi struggle in heavily landscaped areas, T. furfuracea thrives there, sometimes appearing in impressive troops after rain or thaw. The caps are typically only 1-3 cm across with a cinnamon-brown to ochre color that fades as they dry.

Despite being incredibly common, Tubaria furfuracea is often overlooked or misidentified because it looks similar to several other small brown mushrooms, including species of Galerina (some of which are deadly poisonous). Two of the key differences include Tubaria's scurfy cap surface and their preference for well-decayed wood and chips rather than logs. It's a perfect example of how the most abundant fungi often go unnoticed simply because they're small and "plain"—but they're doing important work by breaking down woody debris all around us!
