Summary

Looks like chicken of the woods (Laetiporus), a bracket fungus — visually consistent with the photo's orange/peach shelving fungus at a tree base. It's a popular edible, but "definitely edible" is too strong: ~half of people get GI upset even with correct ID, it must be cooked, young growth only, and specimens on eucalyptus/conifers/yew should be avoided (toxin uptake risk). Can't confirm species or host tree from the photo alone, so verify locally before eating.

Research Analysis

Answer

What is it? Based on the photo's appearance — a bright orange-to-pale, ruffled, shelf-like fungal cluster growing at the base/roots of a tree, with no visible gills — this is visually consistent with "chicken of the woods," the common name for bracket fungi in the genus Laetiporus (species such as L. sulphureus, L. cincinnatus, or L. gilbertsonii depending on region and host tree). I cannot definitively confirm the exact species from a photo alone (that typically requires checking the pore surface color, spore print, and host tree ID), but the coloring, texture, and growth habit match this genus well.

Is it "definitely" edible? No — that's an overstatement. Chicken of the woods is a genuinely popular, widely-eaten wild edible, but real-world edibility comes with important caveats that make "definitely" the wrong word:

1. Host-tree risk is real. The advice is to cook it thoroughly, eat only a small amount the first time, and, above all, avoid chicken of the woods growing on yew, eucalyptus, or conifer trees.[1] Chicken of the Woods growing on certain trees, such as eucalyptus, yew, or conifers, may absorb toxins from the host tree, making it unsafe to consume — Laetiporus gilbertsonii growing on Eucalyptus is a common example.[2] Since the photo shows it growing on a sidewalk tree of unclear species, the host tree needs to be identified before eating.
2. Reactions are common even when correctly identified. About half the people who try Chicken-of-the-Woods Mushrooms end up being sensitive to them, with reactions ranging from mild lip swelling and light-headedness to severe nausea and being quite sick.[3] Reported symptoms range from mild tingling in the lips or stomach upset in mild cases, to vomiting, fever, sweating, raised pulse, and disorientation in severe cases, usually within 2-4 hours of eating.[1]
3. It must be cooked, and only the young, tender parts eaten. As they age they turn whitish and shouldn't be eaten; foragers cut off and gather only the outer edge, the youngest part, since the closer to the tree the woodier the taste gets.[3] Multiple guides stress trying cooking it fully — never eating it raw or undercooked — and trying a small amount the first time even if others have eaten it without issue, since individual sensitivities vary.[4]
4. Urban/roadside specimens carry extra caution. Because this specimen is growing right at a curb/sidewalk next to litter and a parked car, general foraging guidance to avoid urban street trees exposed to pollution, or trees in sprayed lawns and contaminated sites[5] is also relevant — pollutants and root-zone contamination near roads are a separate concern from the mushroom's own toxicity.
5. Look-alikes are a minor concern for this genus. On the positive side, there are no dangerous lookalikes for chicken of the woods at the beginner level — nothing toxic closely resembles this bright shelf fungus[4], though experts still recommend confirming every ID feature (pore surface, growth pattern, host wood) before eating anything foraged.

Bottom line: This is very likely chicken of the woods (Laetiporus sp.), a well-known and generally well-regarded wild edible — but "definitely edible" isn't accurate. Edibility depends on (a) correct species/host-tree identification (avoid eucalyptus, conifers, yew), (b) using only young, fresh material, (c) cooking it thoroughly, and (d) individual tolerance, since a substantial fraction of people experience gastrointestinal upset even with a textbook-perfect specimen. Anyone considering eating this specific find should positively confirm the host tree species and the fungus's pore-surface color before eating, and try only a small cooked portion first.
