Every fall, the Willamette Valley does something that visitors do not expect. The rain returns, the forest floor wakes up, and a surprising number of people in Eugene start walking around with a basket, a hand lens, and a look of private joy. It is mushroom season, and for a few weeks the town’s most reliable small talk is “have you seen anything good?”
We are a florist, not a mycologist, and we say that early because mushrooms are one subject where overconfidence can hurt you. So this is not an identification guide. It is a guide to enjoying the season, to what is on the local calendar, and to the flowers and greenery that capture the same moody, mossy beauty. You may remember that we have already written about flowers that break every rule, including ghost pipe, a plant that lives on fungi. Consider this the sequel.
A note: we have no business relationship with Mount Pisgah Arboretum, the Cascade Mycological Society, Lane Community College, or anyone mentioned below. Dates and details come from the arboretum’s own event page and from published event listings, and they can change. Please confirm with the arboretum before you go.
🌧️ Why October
Mushrooms are the part of a fungus that you can see. The rest of the organism is a network of fine threads, called mycelium, that spreads through soil and wood, often connecting to the roots of trees. When cool, damp weather arrives after a dry summer, many fungi send up their fruiting bodies, and that is why the first real autumn rains are the trigger. Eugene’s long, wet fall is ideal, which is why the area has such an enthusiastic community around it.
📅 What Is on the Calendar
- The Mycoblitz, Thursday, October 15 to Saturday, October 24. According to Mount Pisgah Arboretum’s event page, the Cascade Mycological Society, Lane Community College, and the arboretum are asking people to share photos of mushrooms they have observed in Lane County by uploading them to iNaturalist. The observations are identified by experts and complement the specimen display at the festival. It is a nice, low-impact way to take part: you photograph, you upload, and nothing has to be picked.
- The Mushroom Festival at Mount Pisgah Arboretum, listed for Sunday, October 25. Event listings describe it as an all-day tradition (roughly 10 a.m. to 5 p.m.) with a large exhibit of local species, expert identification tables, talks, guided walks, live music, crafts, mushroom vendors, cider pressing, and hay rides. The listings also say that children under 12 and arboretum members are free, that tickets are sold through the arboretum’s website, and that dogs are not allowed. The arboretum is at 34901 Frank Parrish Road. Because we could not confirm every detail on the arboretum’s own page, please check it before you go.
If you are going to the festival, dress for a wet field: boots, a rain jacket, and layers. Our dinner party guide has a section on dressing for a Eugene evening that applies here, too.
⚠️ Enjoy Them Safely
Some mushrooms are delicious, and some are dangerous, and a few of the dangerous ones look a lot like the delicious ones. A few ground rules from a florist who would like you to stay healthy:
- Never eat a mushroom you cannot identify with certainty. A photo, a guess, or a phone app is not enough. Take it to an expert, such as the identification tables at the festival, and then ask again.
- Look, photograph, and leave it. Observing and uploading to iNaturalist is a good habit, and it is the spirit of the Mycoblitz.
- Check the rules before you pick anything. Whether you can collect mushrooms depends on who manages the land: a city park, a county park, a state or federal forest, a preserve, or private property all have different rules, and some prohibit it altogether. We are not going to try to summarize them. Ask the land manager.
- Keep pets away. Dogs eat things, and some wild mushrooms are toxic to them. If you think a person or a pet has eaten a mushroom they should not have, call a doctor or a veterinarian right away. In the United States, Poison Help is available at 1-800-222-1222.
🍂 The Fungi Palette
Now for the flowers. Mushroom season has a distinctive color story: the cream of a button cap, the golden-orange of a chanterelle, the rust of fallen leaves, the deep green of moss, and the near-black of wet bark. It is a quiet, earthy palette, and it makes an arrangement that looks a little like a walk in the woods.
- Cream and ivory: white and cream chrysanthemums, cream roses, and lisianthus.
- Tan, ochre, and gold: golden mums, wheat-colored grasses, and dried or preserved stems.
- Rust and burgundy: late dahlias while they last (our guide to dahlia season explains the timing), burgundy roses, and chocolate cosmos if you can find it.
- Greens: moss, ferns, seeded eucalyptus, and a few branches with lichen.
- Texture: celosia, with its ruffled, brain-like crests, is the closest thing to a fungus in the flower world. Scabiosa pods and other seed heads add the right kind of oddness.
🌿 Three Forest-Floor Arrangements
1. The Moss Bowl. A low, wide bowl lined with moss, with a few cream mums and burgundy roses tucked in, plus a fern frond or two. It looks like a piece of forest on your table, and because it is low, it is safe for a dinner. Keep the moss damp, but do not flood it.
2. The Chanterelle Corner. A warm, golden bunch of mums, celosia, and rust-colored foliage in a small, simple vase, for a window sill or an entry table. It is bright without being loud, and it lasts for days.
3. The Dried Woodland. Stems that last indefinitely: wheat, grasses, seed pods, preserved ferns, and lichen-covered twigs in a ceramic jar. Our guide to dried and preserved flowers explains how to choose and keep them. It is the one that you set out in October and still love in January.
🚫 What Not to Put in a Vase
- Wild mushrooms. Real mushrooms wilt, rot, and attract insects within a day or two, and some are toxic to children and pets. If you want the look, choose artificial, ceramic, felted, or carved mushrooms.
- Ghost pipe. It is a fascinating plant, and a fragile one. We would leave it in the woods, where it belongs, and enjoy it with a camera.
- Anything you have gathered on land where collecting is not allowed. This applies to moss, branches, and lichen too. Check the rules first.
Greenery from a florist is a good alternative. Ask us about moss, ferns, and branches for exactly this kind of arrangement, and we will build one to your taste from what is available that week. For care tips, our pro tips have the basics.
🎁 A Gift for the Fungi Friend
Everyone seems to have one: a friend, a coworker, or a relative who disappears into the woods every October and returns with a story. A small moss-and-rust arrangement is a lovely thing to send them, with a card that says something like “Thank you for being a fungi to be around.” (We know. We could not help ourselves.) It also works for a host, a teacher, or a naturalist who has taught you something. Our thank-you flowers page has more ideas, and we deliver across Eugene, Springfield, and Lane County.
🧡 The Short Version
Photograph the mushrooms, do not eat what you cannot identify, and check the rules before you pick anything. Go to the festival if you can. And bring a little of the forest inside, in moss, rust, and cream, without the real thing. If the season has you thinking about the rain, our love letter to Eugene’s weather explains why the drizzle is the point.
