Wood Blewit Lepista nuda
The wood blewit is one of the most recognizable late-season mushrooms in the Pacific Northwest. Its violet to lilac coloring — visible on the cap, gills, and stem — makes it stand out against the brown leaf litter where it typically fruits. Found from October through December, blewits often appear after the first hard frosts when most other species have finished for the year.
Taxonomically, this species has been shuffled between Lepista nuda, Clitocybe nuda, and Collybia nuda. You’ll see all three names in field guides. Regardless of the label, the mushroom is the same: a robust, saprotrophic species that breaks down leaf litter and organic debris in forests, gardens, and compost piles across the region.
Identification
- Cap: 6–15 cm, convex becoming flat with age; violet to lilac-brown, fading to tan in dry conditions; smooth, slightly sticky when wet
- Gills: Crowded, sinuate to slightly decurrent; violet when young, fading to buff-brown with age
- Stipe: 5–10 cm tall, 1.5–3 cm thick; stout and fibrous; lilac to pale violet, often with a slightly swollen base
- Spore Print: Pale pinkish-buff
- Odor: Mildly fragrant — often described as slightly floral or perfumed
- Season: Late fall through early winter (October–December in the PNW)
The violet coloring is the key feature, but be aware that it fades significantly in older specimens and after rain. Fresh, young blewits can be strikingly purple throughout, while weathered ones may appear almost entirely brown with only a faint lilac tinge at the gill edges. Always check for the combination of violet gills, pale pinkish spore print, and the characteristic fragrant odor.

Habitat & Where to Find Them
Unlike most gourmet mushrooms in the Pacific Northwest, wood blewits are saprotrophic — they feed on decomposing organic matter rather than forming mycorrhizal partnerships with trees. This means you’ll find them in habitats rich in leaf litter and decaying plant material:
- Deciduous leaf litter: Under oaks, cottonwoods, alders, and maples — anywhere leaves accumulate in thick layers
- Garden borders and compost: Blewits love well-composted garden beds, wood chip mulch, and the edges of compost piles
- Mixed woodland edges: Forest margins where deciduous and coniferous trees meet, with deep duff layers
- Parks and urban green spaces: One of the few gourmet species that fruits reliably in landscaped areas
In western Washington and Oregon, look for blewits after sustained fall rains when nighttime temperatures drop below 50°F (10°C). They often appear in the same spots year after year, so a productive patch is worth revisiting. Use the Forayz map to check current soil temperature and precipitation data for your area.
Lookalikes & Safety
The wood blewit’s purple coloring narrows the field of potential lookalikes considerably, but there are a few species to be aware of. For a broader overview of toxic mushrooms in the Pacific Northwest, see our dedicated page.
- Cortinarius species (webcaps): This is the most important group to distinguish. Several purple Cortinarius species share similar coloring, and some are dangerously toxic. The key difference: Cortinarius have rusty-brown spore prints (blewits have pinkish-buff), and young specimens show a cobweb-like cortina (partial veil) between the cap edge and stem. If you see any trace of a cortina or rusty-brown spores — it is not a blewit.
- Lepista sordida (sordid blewit): A smaller, thinner species with similar purple coloring. Edible but less substantial. Not dangerous, just less desirable.
- Clitocybe species: Some pale Clitocybe species can appear similar to faded blewits. Check for the violet tones on the gills and stem — true blewits retain at least some lilac color even when faded.
The critical rule: If you’re collecting purple mushrooms and you see a rusty-brown spore print or any sign of a cobweb veil, stop. You likely have a Cortinarius, and some species in that genus cause delayed kidney failure. Always take a spore print when collecting blewits for the first time.
Cooking & Edibility
Wood blewits are a good edible mushroom with a mild, slightly sweet flavor and a firm, meaty texture that holds up well in cooking. A few important notes:
- Always cook thoroughly. Raw blewits can cause gastrointestinal upset. A minimum of 15 minutes of cooking is recommended.
- Sauteing: The most common preparation. Cook in butter over medium heat until the moisture releases and the edges begin to brown. Pairs well with garlic, thyme, and cream sauces.
- Soups and stews: Their firm texture makes them excellent in heartier dishes. They hold their shape well and don’t become slimy.
- Drying: Blewits dry well and can be rehydrated for year-round use, though their flavor is better fresh.
- Alcohol note: Some people report mild reactions when consuming blewits with alcohol. If you’re new to eating them, try them without alcohol the first time. For more on mushroom-alcohol interactions, see our article on morels and alcohol toxicity.
Where to Look: Habitats & Associated Trees
Wood blewits are saprotrophic — they decompose leaf litter rather than partnering with living tree roots. But the trees that produce that litter are your best guide to finding productive blewit habitat. Here are the key tree species to look under in the Pacific Northwest.
