Each corner of this state holds a discovery for mycologists. This abundant diversity makes Rhode Island home to some of the 20 most common mushroom species flourishing in its varied habitats featuring woodlands, coastal wetlands, and urban parks. Unearth the richness of these intriguing fungi in our guide.

Most Common Mushrooms

Chicken of the woods

1. Chicken of the woods

Chicken of the woods is very noticeable in hardwood forests, appearing in clusters on standing tree trunks in bright orange and yellow hues that sometimes last through the entire winter. It is a parasite that causes an unfortunate brown heart rot, and is considered a particularly troublesome pest of Yew trees. If the fruitbodies can be seen, the tree is likely already beyond saving.
Birch polypore

2. Birch polypore

The birch polypore has a variety of applications. Its thick skin has been used by barbers as a razor sharpener and as a mount for insect collectors. When dried, this mushroom was also used to carry fire over long distances because it burns slowly. The historical use of birch polypore doesn't stop there; pieces of this mushroom were found being carried by the five-thousand-year-old mummy Ötzi the Iceman.
Turkey tail

3. Turkey tail

The distinctively-striped turkey tail fungus grows on stumps and logs all over the forests of the northern hemisphere. It is, in fact, probably the most common species you will find. That doesn't mean this mushroom is plain, however; each cap is uniquely patterned. Look for bands of alternating textures as well as color.
Cedar-apple rust

4. Cedar-apple rust

The vividly-colored fruitbodies of cedar-apple rust (Gymnosporangium juniperi-virginianae) might be mistaken for flowers, from a distance. Upon closer inspection they can be identified as fungal growths attacking the fruit of cedar trees. Their microscopic spores can travel up to an astounding 5 miles when carried on the wind and infect cedars quite far away, weakening the trees as they grow.
Fly agaric

5. Fly agaric

In Northern Asia and Europe, fly agaric grows under trees near the winter solstice and is collected for ritual use tied to the season. Its characteristic shape and coloring are still ubiquitous in many European fairy tale illustrations and Christmas traditions. It is highly toxic.
Smooth rock tripe

6. Smooth rock tripe

Smooth rock tripe is one of the largest types of lichen in the world. The vegetative part of a lichen's body has been recorded reaching 63 cm across. Though directly translating to "small-breasted," the mammulata epithet was given because many specimens develop a navel-like shape. The common name of "tripe" references its similarity to the food of the same name.
Spotted cort

7. Spotted cort

Spotted cort thrives in oak forests due to the mutually beneficial relationship it has with the trees’ roots. The mushroom provides nutrition to the tree and keeps the soil chemistry favorable for both species. The lavender-hued caps make spotted cort easy to identify, even when brown age spots start to appear.
Bush beard lichen

8. Bush beard lichen

Bush beard lichen is a shrub-like lichen. It is called Bush beard lichen after its white and dangling heads that have the appearance of beards. It is incredibly small at only 4 cm tall and can be found on deadwood bark.
Black knot

9. Black knot

The appearance of black knot (Apiosporina morbosa) is commonly found on various fruit-bearing trees and looks more like abnormally growing bark than it does a fungus. In youth, this bulbous growth is a lighter green but rapidly turns to dark brown and black. Black knot can kill trees and is not easily controllable using fungicides.
Dryad's saddle

10. Dryad's saddle

A familiar sight to spring morel hunters, dryad's saddle is noteworthy for its large size, striking scales, and watermelon-like smell. Similar to other mushrooms in the bracket fungi family, dryad's saddle can be used to make paper. Younger mushrooms are better suited for this purpose due to their smaller and more consistent fibers.
