| 中文摘要: |
| 系统发育分析结果表明，尽管Lanzia berggrenii能在寄主中形成基物子座，但与膜盘菌属的核心种关系较近，而与蜡盘菌科成员关系较远，应该归属于膜盘菌属。在广义的膜盘菌属的系统树中该种及在新西兰发现的4个新种构成一个单系群，分别命名为Hymenoscyphus haasticus，H. kiko，H. ohakune和 H. waikaia。它们的共同特征：基物均为南青冈叶片，侧丝顶端分枝形成类似囊层被的结构，覆盖于子实层上部。Lanzia berggrenii var. metrosideri 应为膜盘菌属中一个独立的种，即 Hymenoscyphus metrosideri。 |
| 英文摘要: |
| Phylogenetic analysis shows that Lanzia berggrenii is closely related to the core Hymenoscyphus clade, rather than the Rutstroemiceae, despite this species being associated with the development of stromatic tissue on its host substrate. Accepted here in the genus Hymenoscyphus, H. berggrenii and four newly described species from New Zealand form a monophyletic group within Hymenoscyphus sensu lato. All are known only from Nothofagus leaves, and all share distinctive paraphyses, having short side branches near the apex and forming an epithecium-like layer across the top of the asci. The four new species are here named as Hymenoscyphus haasticus, H. kiko, H. ohakune, and H. waikaia. A key is provided for the five Nothofagus inhabiting species. Lanzia berggrenii var. metrosideri is accepted as a distinct species, under an existing combination Hymenoscyphus metrosideri. Its true generic position awaits a better understanding of the phylogenetic diversity of groups such as Hymenoscyphus, Vibrissea and the Hyaloscyphaceae. |
