| description | In this study, four new species of <i>Russula</i> subg. <i>Brevipedum</i> collected from China are described based on morphological characteristics and molecular evidence. <i>Russula brevispora</i> has a white body whose whole parts often stain brownish-orange or grayish-orange, extremely crowded lamellae with the presence of lamellulae, basidiospores with low warts and an inamyloid suprahilar spot, and clavate or lageniform hymenial cystidia often with a papillary or submoniliform appendage. <i>Russula flavescens</i> is characterized by a white pileus often turning yellowish brown when touched, white lamellae turning brown or light orange, basidiospores with an inamyloid suprahilar spot, and fusiform hymenial cystidia often with an appendage. <i>Russula longicollis</i> is morphologically characterized by a white pileus, turning grayish orange when bruised, white lamellae turning pale yellow when bruised, basidiospores with isolated warts and an amyloid suprahilar spot, and fusiform hymenial cystidia usually with a long appendage. <i>Russula pseudojaponica</i> has a yellowish-brown pileus center, yellowish lamellae unchanging when bruised, basidiospores with low warts and an inamyloid suprahilar spot, clavate hymenial cystidia often with a papillary appendage, and clavate pileocystidia with granulose contents. Phylogenetic analyses showed that <i>R. flavescens</i>, <i>R. brevispora</i>, and <i>R. pseudojaponica</i> are members of the subsect. <i>Pallidosporinae</i>, whereas <i>R. longicollis</i> belongs to subsect. <i>Lactarioideae</i>, and is somewhat related to <i>R. leucocarpa</i>. |
