Coral Mushrooms Ramaria and related genera — the branching fungi of PNW forests
Coral mushrooms are some of the most visually striking fungi in the Pacific Northwest. They look like underwater corals transplanted to the forest floor — clusters of branching, upright fingers in colors ranging from bright orange and crimson to pale yellow and purple. Most belong to the genus Ramaria, but several other genera produce coral-like forms.
They’re also some of the hardest mushrooms to identify to species. Many Ramaria species look nearly identical in the field, and confident identification often requires microscopy, chemical tests, or DNA sequencing. Most foragers learn to appreciate corals for what they are — beautiful and ecologically important — without worrying too much about exact species names.

What Makes a Coral Mushroom
Coral mushrooms share a distinctive growth form: upright, branching fruitbodies that emerge from the ground or from decaying wood. They lack caps and gills entirely. Instead, spores are produced on the outer surface of the branches.
Several genera produce coral-like fruitbodies in the PNW:
| Genus | Key Features | Common Species |
|---|---|---|
| Ramaria | Large, fleshy, repeatedly branching from a thick base. Most are mycorrhizal with conifers. The dominant coral genus — dozens of species in the PNW. | Pink-tipped coral, lemon coral, crimson coral, yellow spring coral, orange jelly coral |
| Clavulina | Smaller, with blunt or crested branch tips. Often white to grayish. Frequently parasitized by a dark fungus that turns parts black. | Crested coral (C. coralloides) |
| Clavariadelphus | Club-shaped rather than branching — single or clustered upright columns. Some are edible and surprisingly sweet. | Candy club (C. truncatus), western clubs |
| Artomyces | Grows on wood (not soil). Crown-like tips distinguish it from ground-dwelling corals. | Crown coral (A. pyxidatus) |
| Alloclavaria | Unbranched or minimally branched. Deep purple color is unmistakable. | Purple club coral (A. purpurea) |
Ground vs. Wood
Most Ramaria species grow from the ground and are mycorrhizal — connected to living tree roots. If you find a coral growing directly on a log or dead wood, it’s likely Artomyces, Ramaria rubella, or another wood-decomposing species. This is one of the first things to check in the field.
Field Identification Tips
Getting coral mushrooms to species is genuinely difficult, even for experienced mycologists. But a few field observations can narrow things down considerably:
- Branch tip color: This is the single most useful field character. Pink, red, purple, yellow, orange, or white tips all point to different species groups.
- Base/stipe color: Some species have a distinctly different color at the base than the branches. A white base with yellow branches is different from a yellow base throughout.
- Bruising reaction: Cut or handle the branches and watch for color changes over 30–60 seconds. Some species bruise brown, reddish, or don’t change at all.
- Taste: Chew a small piece and spit it out. Bitter, acrid, or mild? This eliminates many species. (Bitter corals are not worth eating regardless of ID.)
- Size and stature: Some Ramaria species reach 25 cm tall with chunky bases. Others are small and delicate. Overall architecture matters.
- Substrate: Ground (mycorrhizal), duff/litter, or wood? Ground-dwelling species are usually Ramaria. Wood-dwelling species are different genera.
- Associated trees: Hemlock, spruce, fir, and tanoak associations help narrow down Ramaria species.
Notable PNW Coral Species
Pink-Tipped Corals (Ramaria rubrievanescens)
One of the most common and recognizable fall corals. Chunky base with branches that have vinaceous pink to wine-red tips when young — the pink color fades as the mushroom ages. Edible and good, but easily confused with bland or bitter species that look similar. Found under conifers throughout western Cascadia.
Orange Jelly Coral (Ramaria sandaracina)
Bright orange throughout, especially at the tips. Forms crowded clusters of slender upright branches. Common and abundant in coastal spruce forests, especially in wetter areas of Cascadia. Edibility unknown.
Crimson Coral (Ramaria araiospora)
Compact clusters with bright crimson-red to neon-red branches arising from a slender base. Visually stunning. Edible but bland. Locally common at lower elevations in west-side hemlock and spruce forests. Fall fruiting.
Lemon Coral (Ramaria cystidiophora)
Slender crowns of bright to pale lemon-yellow branches. Associated with hemlock. Locally common in west-side forests. Likely edible.
Yellow Spring Coral (Ramaria rasilispora)
The one spring coral worth knowing. Pale yellow to greenish-yellow, forming compact clusters that often stay hidden under duff until mature. Common and abundant on the east side of the Cascades and in drier microclimates. Edible and quite good — often overlooked by morel hunters in spring. Cook well and sample in moderation the first time.
Candy Club (Clavariadelphus truncatus)
Not a branching coral but a fat, flat-topped club. Distinctively sweet-tasting — one of the few mushrooms you can identify by flavor alone. Edible. Found under conifers in fall.
Blah Coral (Ramaria acrisiccescens)
Tall, slender, whitish to pale beige. The common name says it all — the taste is a deterrent. Very common under hemlock across western Cascadia in fall. Worth knowing so you don’t waste time on it.
Season & Timing
Most coral mushrooms in the PNW are fall fruiters, with peak season tracking the same fall rain patterns that trigger chanterelles and other mycorrhizal species. One notable exception: the yellow spring coral (R. rasilispora) fruits in spring on the east side of the Cascades, often alongside morels.

Edibility
The edibility situation with coral mushrooms is complicated. A handful of Ramaria species are genuinely good edibles. Many others are bland, bitter, or have unknown safety profiles. Some cause GI upset.
- Good edibles: R. rubrievanescens (pink-tipped), R. rubiginosa (red-staining yellow), R. rasilispora (yellow spring coral), and Clavariadelphus truncatus (candy club) are considered edible and good.
- Likely edible: R. cystidiophora (lemon coral) and R. velocimutans are likely safe but less established.
- GI risk: The R. formosa group (yellow-tipped corals) has been associated with gastrointestinal problems. Since R. formosa has been a catchall name for many species, the exact culprit is unclear.
- Unknown: Many species, including some common ones like orange jelly coral and purple prince coral, have unknown edibility.
The Identification Problem
The practical challenge with eating coral mushrooms isn’t toxicity — no Ramaria is known to be dangerously poisonous. The problem is confident identification. The edible species look very similar to the bland, bitter, or GI-causing species. Unless you can reliably distinguish your target species, it’s safer to admire corals than to eat them.
If you do try eating a coral mushroom, start with a small portion and wait 24 hours before eating more. The yellow spring coral (R. rasilispora) is the best starting point — it fruits in spring (not fall), on the east side of the Cascades, which narrows the ID considerably.
Habitat & Ecology
Most Ramaria species are mycorrhizal — they form underground partnerships with living tree roots, just like chanterelles and boletes. This means they’re tied to specific forest types and tree associations.
- Western hemlock forests: The most productive habitat for fall corals in western Cascadia. Many species, including lemon coral and blah coral, associate specifically with hemlock.
- Spruce forests: Coastal Sitka spruce stands are excellent for orange jelly coral and other species.
- True fir forests: Mid to high elevation stands with silver fir, noble fir, or subalpine fir produce a different suite of corals.
- East-side dry forests: The yellow spring coral is most common on the east side of the Cascades in drier conifer forests with ponderosa pine and Douglas fir.
- Tanoak forests: In southern Oregon, R. rubiginosa (red-staining yellow coral) is locally common with tanoak.
Look for corals in mature to old-growth forests with deep duff and moss. They often fruit in troops or arcs — finding one usually means more are nearby.
