摘要：
Hygrocybe aurantiomagnifica (Agaricales), which we describe here as a new species, is characterised by gregarious basidiomata, yellow to orange pileus with an almost plane, smooth surface and undulate or lobed margin; distant, whitish lamellae becoming pinkish-violet at the edge; absence of cheilocystidia and an enterocutis pileipellis. Morphological along with molecular phylogenetic analyses of the internal transcribed spacer (nrITS) and the nuclear large subunit (nrLSU), confirm H. aurantiomagnifica as a new species of subgenus Pseudohygrocybe section Firmae. A comprehensive morphological description, illustrations, comparisons with related species and a key including similar Brazilian species are provided.
