Lookalikes to rule out
Coral fungi
cautionRamaria corals have rounded, upright branches rather than flat, ribbon-like lobes; several cause gastrointestinal upset.
Hen of the Woods
harmlessHen of the woods is gray-brown with spoon-shaped fronds and a pore surface underneath.
Other Sparassis species
harmlessWestern and eastern North American cauliflower mushrooms are separate species with similar form.
Identification
The fruiting body is a compact to large rosette, often the size of a head of lettuce, made of many flattened, wavy lobes like egg noodles. Color is creamy white to pale yellow, browning at the edges with age. It rises from a single rooting base attached to a conifer root. There are no gills, pores, or teeth.
Uses and ecology
Cauliflower mushrooms cause a brown rot in the roots and butt of conifers and can return at the same tree for years. Cut above the base to leave the attachment intact. Soil and needles collect between the lobes, so clean carefully. Texture stays firm when cooked.
Memorable fact
A single rosette can weigh several kilograms, and the same tree may produce one for many consecutive years.
