Cantharellus rubescens is described and illustrated as new species from the semi-arid of Northeastern Brazil. It is recognized by orange-yellow basidiomes, hymenophore and contex with a strong reddening-orange reaction, scaly stipe, basidiospores measuring 6-7.5(-9) x 4-5(-5.5) mu m and having thick-walled (1-1.5 mu m), terminal elements in the pileipellis. Morphological differences with other, orange-yellow Brazilian Cantharellus species are discussed, such as C. aurantioconspicuus, C. guyanensis and C. protectus.
