During the collection of macrofungi resources in Son Tra Nature Reserve, Danang, Vietnam, two fungal specimens of the genus , designated as M34295 and M3457, living on dead still-attached branches of L. at an elevation around 360 m above the sea level were recorded. The morphological characteristics of the specimens shared some common characteristics with spp. However, the specimens possessed some distinct characteristics from other species. The phylogenetic analyses based on the combined internal transcribed spacer (ITS) and Large Subunit (LSU) molecular markers of ribosomal genes revealed that the two specimens clustered in a single clade at species level with all tested species with strong bootstrap support of 99%. Among genus, our specimens seemed closest to in morphological and genetic characteristics. Based on the combination of morphological approaches and multilocus phylogenetic analyses, we introduced sp. nov. as a new species. was characterized by its skewed bell-like basidiome with the color of dark blue to midnight blue, 1.0 - 1.5 cm diam, stipeless, light pink lamellae, sparse, occasionally branching. Basidiospores broadly ovoid to subglobose, 6-7 × 5.5-6 µm. To our knowledge, this is the first record of fungus in Vietnam.
在越南岘港山茶自然保护区进行大型真菌资源采集期间，记录到两个 属的真菌标本，编号为M34295和M3457，它们生长在海拔约360米处的 枯死但仍附着的树枝上。这些标本的形态特征与 属的一些物种有一些共同特征。然而，这些标本具有一些与其他 物种不同的独特特征。基于核糖体 基因的内部转录间隔区（ITS）和大亚基（LSU）分子标记的系统发育分析表明，这两个标本在物种水平上聚集在一个单系分支中，与所有测试的 物种聚在一起，自展支持率高达99%。在 属中，我们的标本在形态和遗传特征上似乎最接近 。基于形态学方法和多位点系统发育分析的结合，我们描述了 新种。 新种的特征是其偏斜的钟形担子果，颜色为深蓝色至午夜蓝，直径1.0 - 1.5厘米，无柄，菌褶浅粉色，稀疏，偶尔分枝。担孢子宽卵形至近球形，6 - 7×5.5 - 6微米。据我们所知，这是该真菌在越南的首次记录。
