## Appearance

The Cortinariaceae has a diverse appearance, often featuring rust-brown spores that can dust the stem or a spiderweb-like veil. Caps vary from conical to convex, frequently displaying scaly or silky textures in earthy tones like brown, purple, or olive.

## Taxonomy

- **Kingdom:** Fungi
- **Phylum:** Basidiomycota
- **Class:** Agaricomycetes
- **Order:** Agaricales
- **Family:** Cortinariaceae

## Interesting facts

- Even tiny pieces of certain Cortinariaceae can cause serious kidney damage if eaten.
- Many species have a unique "cortina," a spiderweb-like veil, protecting their young gills.
- Some Cortinarius mushrooms smell like radishes, a surprising and helpful identification clue!
- The Cortinariaceae family is one of the largest mushroom groups, with thousands of species!

## Special abilities

- **Nutrient Connectors:** Cortinariaceae can form mycorrhizal networks that help trees absorb essential nutrients and water from the soil.
- **Chemical Defenders:** Cortinariaceae has compounds that make them poisonous, deterring animals from eating them and protecting their spores.
- **Spore Sprinklers:** Many species have rust-brown spores that readily detach, helping them spread far and wide to new locations.

## Traits

- [Solitary](https://www.snappit.app/explore/traits/solitary): Solitary animals live alone for most of their lives, only interacting with others for mating or parental care.
- [Colorful](https://www.snappit.app/explore/traits/colorful): Colorful describes organisms or objects displaying a wide range of bright and distinct colors.
- [Decomposer](https://www.snappit.app/explore/traits/decomposer): Describes organisms that break down dead organic material, recycling nutrients back into the ecosystem.
- [Forest](https://www.snappit.app/explore/traits/forest): Forest habitats are terrestrial environments dominated by dense tree cover, supporting a high diversity of plant and animal life.
- [Aquatic](https://www.snappit.app/explore/traits/aquatic): Aquatic habitats encompass environments where organisms live predominantly in water, including oceans, rivers, lakes, and wetlands.

## Safety

**Danger:** 1/5 · Very low

Always ask an adult before touching or picking mushrooms.
