Data from: The genus Vararia (Russulales, Basidiomycota) in China 1. two new species and two new Chinese records

Two new species, Vararia bispora and V. montana collected from southern China, are described and illustrated based on morphological characters. Vararia bispora is characterized by cinnamon-buff to yellowish brown basidiocarps, clamped generative hyphae, ventricose gloeocystidia, 2-sterigmata basidia, and large fusiform to cylindrical basidiospores that are negative in Melzer's reagent. Vararia montana is characterized by small pulvinate basidiocarps, clamped generative hyphae, rather strongly dextrinoid dichohyphae, and broadly ellipsoid basidiospores with a peculiar beak-like extension, and without reactions in Melzer's reagent. In addition, V. ambigua and V. amphithallica are reported from China for the first time, and descriptions and illustrations are also provided for these two species.本研究基于形态学特征，对采自中国南方的两个新种——双孢伏革菌（Vararia bispora）与山地伏革菌（V. montana）进行了描述与图解。双孢伏革菌的鉴别特征为：担子果呈肉桂茶色至黄褐色，生殖菌丝具锁状联合，粘囊体呈腹膨形，担子具2个小梗，担孢子为大型纺锤形至圆柱形，在梅尔泽试剂（Melzer's reagent）中呈负反应。山地伏革菌的鉴别特征为：担子果小型垫状，生殖菌丝具锁状联合，二叉状菌丝呈强糊精反应，担孢子为宽椭圆形且具独特的喙状突起，在梅尔泽试剂中无显色反应。此外，歧义伏革菌（V. ambigua）与两体伏革菌（V. amphithallica）为中国首次报道的物种，本研究亦对这两个物种进行了形态描述与图解。
