摘要本文对华中属植物进行了分类和系统发育分析。利用ITS和nLSU序列对3个新种进行了形态特征和分子系统发育分析。它们是J. austrosinensis。11月，J.南狄纳斯。11 .和J. subcollabenssp.。11月，奥地利青花的特点是：重旋，薄的担子瘤，白色至浅黄色的膜包膜，小孔（9-11 / mm），夹紧的生菌丝，具有膜囊，椭圆形担子孢子（2.5-3 × 1.7-2µm），生长在落竹或被子植物枝上。南花花属（junhuhnia nandinae）的特征是：再生的担子孢子具有粉红色至橙红色的气孔和明显的白色边缘，钳生菌丝，交织的菌丝，椭圆形的担子孢子，大小为2.6-3.2 × 1.8-2µm，生长在南花上。幼花的特征是：再生的担子孢子，膜层呈浅橙红色至褐色，气孔小（10-12 / mm），生生菌丝具有简单的隔和夹接，菌丝交织，月形担子孢子大小为2.9-3.4 × 1.6-1.8µm，生长在被子植物的腐木上。
Abstract In this study, taxonomic and phylogenetic analyses of Junghuhnia were performed. Three new species were characterised according to morphological characteristics and molecular phylogenetic analysis using ITS and nLSU sequences. They are J. austrosinensissp. nov., J. nandinaesp. nov. and J. subcollabenssp. nov.Junghuhnia austrosinensis is characterised by resupinate, thin basidiomata with white to buff-yellow hymenophore, small pores (9–11 per mm), clamped generative hyphae possessing hymenial cystidia, ellipsoid basidiospores (2.5–3 × 1.7–2 µm) and growth on fallen bamboo or angiosperm branch. Junghuhnia nandinae is characterised by resupinate basidiomata with pink to salmon pores and a distinct white margin, clamp generative hyphae, interwoven tramal hyphae, ellipsoid basidiospores measuring 2.6–3.2 × 1.8–2 µm and growth on Nandina domestica. Junghuhnia subcollabens is characterised by resupinate basidiomata with pale salmon to brownish vinaceous hymenophore, small pores (10–12 per mm), generative hyphae with simple septa and clamp connections, interwoven tramal hyphae, lunate basidiospores measuring 2.9–3.4 × 1.6–1.8 µm and thriving on rotten wood of angiosperms.
