Inocybe rimosa

Inocybe rimosa is a species of mushroom in the genus Inocybe. It is commonly known as the split fibercap. This mushroom is characterized by its small size, brownish cap, and fibrous stem.

Description

Inocybe rimosa typically has a cap that ranges from 1 to 4 centimeters in diameter. The cap is initially convex but flattens with age. It is brown in color and often has a fibrous texture. The gills of this mushroom are adnate, meaning they are attached to the stem. The stem is slender and can grow up to 8 centimeters tall.

Distribution and Habitat

This species is widely distributed in North America and Europe. It is commonly found in wooded areas, particularly in deciduous forests. Inocybe rimosa is a saprotrophic fungus, meaning it obtains nutrients by decomposing organic matter in the soil.

Toxicity

Inocybe rimosa is considered to be toxic. It contains the toxin muscarine, which can cause symptoms such as nausea, vomiting, diarrhea, and sweating if ingested. It is important to exercise caution when foraging for wild mushrooms and to accurately identify species before consumption.

Similar Species

Several other species of Inocybe mushrooms closely resemble Inocybe rimosa. These include Inocybe geophylla and Inocybe maculata. Proper identification of these mushrooms is crucial due to the potential toxicity of some species within the genus.
