Two new species of Tricholomopsis (Agaricales) from China based on molecular phylogenetic and morphological evidence
Abstract
Tricholomopsis is a genus of tricholomoid fungi, typically saprotrophic, characterized by a fibrillose to squamulose pileus, yellow lamellae, and prominent cheilocystidia. In this study, two new species of Tricholomopsis , namely T. roseorubra and T. cortinata , are described based on morphological characteristics and phylogenetic analyses of ITS–28S sequences. Tricholomopsis roseorubra is characterized by purplish-red, squamulose basidiomata and prominent cheilocystidia forming a sterile gill edge, whereas T. cortinata is distinguished by small basidiomata, globose basidiospores, and a well-developed cortinate annulus. The latter represents the first record of a cortinate annulus in Tricholomopsis .
