Abstract

Two new species of Chalciporus are described from southern China. Chalciporus citrinoaurantius sp. nov. is characterized by a lemon yellow to grayish orange pileus, light orange to rose pink tubes and elongated basidiospores (9.0)9.5–12.5(13) × 3–4(4.5) μm; C. hainanensis sp. nov. is characterized by small basidiomata with grayish yellow to brownish orange pilei, orange yellow to brownish orange tubes with brownish orange to brownish red pores and elliptic basidiospores 8–10.5(11) × 4–5(5.5) μm. Phylogenetic analysis based on the combined dataset (nrLSU+tef1-α+rpb2) confirmed the affinity of the new species in Chalciporus and indicated their relationships with other species within the genus.
