摘要 对来自中国不同地区的 Rugonectria 和 Thelonectria 的最新收藏品和植物标本进行了检查。通过形态学和分子数据的综合分析,识别出 17 个物种,其中包括 3 个 Rugonectria 物种和 14 个 Thelonectria 物种。其中,R.microconidia和T.g​​uangdongensis是科学上的新事物。苔藓树皮上的 Rugonectriamicroconidia 的特征是浅表、黄色至橙色、梨形至近球形子囊壳,表面有疣状;椭圆形到宽椭圆形、有条纹、单隔膜的子囊孢子;尿囊状至棒状、无隔膜的小分生孢子。广东龙舌兰具有鲜红色的子囊壳,表面稍粗糙,有明显的深色乳头;椭圆形,光滑,单隔膜子囊孢子;以及近圆柱形、稍微弯曲、多隔膜的大分生孢子。讨论了新物种与其近亲之间的形态差异和序列差异。记录了中国先前记录物种的名称变化。
Abstract Recent collections and herbarium specimens of Rugonectria and Thelonectria from different regions of China were examined. Using combined analyses of morphological and molecular data, 17 species are recognised including three species of Rugonectria and 14 species in Thelonectria. Amongst them, R.microconidia and T.guangdongensis are new to science. Rugonectriamicroconidia on mossy bark is characterised by superficial, yellow to orange, pyriform to subglobose perithecia with a warted surface; ellipsoidal to broadly ellipsoidal, striate, uniseptate ascospores; and allantoid to rod-shaped, aseptate microconidia. Thelonectriaguangdongensis possesses bright red perithecia with a slightly roughened surface and a prominently dark papilla; ellipsoidal, smooth, uniseptate ascospores; and subcylindrical, slightly curved, multiseptate macroconidia. Morphological distinctions and sequence divergences between the new species and their close relatives are discussed. Name changes for the previously recorded species in China are noted.
