The color of the fruit body is brownish to yellow, becoming paler toward extremities. It bruises light reddish brown. The basidiocarp has a leathery texture when fresh, but becomes brittle when dry. Growing from a whitish base, the stipe is branched up to 8 times, the branches all upright and nearly parallel, each ending in 4 to 5 thornlike tips. Overall, the fruit body appears bushy, and is medium-sized, up to . The stipe is single or branching from the base, with white
mycelium and
rhizomorphs radiating from the base. The odor is of anise and the taste is bitter. The
spore print is dark yellow. The
spores are roughly elliptical, dotted with low
cyanophilous warts, and measure 7–10 by 3.5–5.5
μm. The
basidia have basal clamps, are mostly four-spored, and sometimes have cyanophilous granular contents.

violaceo-tincta Similar species Another widespread and common coral,
R. apiculata, typically grows on
conifer wood and bruises brown like
R. stricta, but has green pigmentation.
R. apiculata is a dull buff-tan to dull orange-brown and the young fruit bodies often have white branch tips.
R. gracilis prefers conifer wood and has lighter colors than
R. stricta. The tropical
R. moelleriana can only be reliably distinguished from
R. sticta by location and microscopic characteristics.
R. flava is
mycorrhizal and grows under coniferous and deciduous trees. Its fruit bodies are typically taller, with a more unpleasant odor and a less bitter taste.
R. rubella (also known as
R. acris) is pinkish tan and
R. tsugina stains green. ==Distribution and habitat==
