Species in the genus Gliocephalotrichum (= Leuconectria) (Hypocreales, Nectriaceae) are soilborne fungi, associated with post-harvest fruit spoilage of several important tropical fruit crops. Contemporary taxonomic studies of these fungi have relied on morphology and DNA sequence comparisons of the internal transcribed spacer region of the nuclear rDNA (ITS) and the β-tubulin gene regions. Employing DNA sequence data from four loci (β-tubulin, histone H3, ITS, and translation elongation factor 1-alpha) and morphological comparisons, the taxonomic status of the genus Gliocephalotrichum was re-evaluated. As a result five species are newly described, namely G. humicola (Taiwan, soil), G. mexicanum (rambutan fruit from Mexico), G. nephelii (rambutan fruit from Guatemala), G. queenslandicum (Australia, endophytic isolations) and G. simmonsii (rambutan fruit from Guatemala). Although species of Gliocephalotrichum are generally not regarded as important plant pathogens, their ability to cause post-harvest fruit rot could have an impact on fruit export and storage.
Gliocephalotrichum 属（= Leuconectria）（Hypocreales，Nectriaceae）中的物种是土壤真菌，与几种重要热带水果作物的采后果实腐烂有关。这些真菌的当代分类学研究依赖于核 rDNA（ITS）和β-微管蛋白基因区域的内部转录间隔区的形态和 DNA 序列比较。利用来自四个基因座（β-微管蛋白、组蛋白 H3、ITS 和翻译延伸因子 1-α）的 DNA 序列数据和形态比较，重新评估了 Gliocephalotrichum 属的分类地位。结果，新描述了五个物种，即 G. humicola（台湾，土壤）、G. mexicanum（来自墨西哥的红毛丹果实）、G. nephelii（来自危地马拉的红毛丹果实）、G. queenslandicum（澳大利亚，内生分离物）和 G. simmonsii（来自危地马拉的红毛丹果实）。虽然 Gliocephalotrichum 属的物种通常不被认为是重要的植物病原体，但它们引起采后果实腐烂的能力可能会对水果出口和储存产生影响。
