本文报道了Athelia一新种，A.根据形态学和系统发育学分析，描述了产自日本的一种白蚁属（termitophila）。该种的担子组的特征是具有菌丝，有时在隔膜处具有钳状连接，担子在基部隔膜处没有钳状连接，和椭圆形至卵圆形的担孢子，测量4.5-6 x 3-4.5 mm。菌核的形状和大小与其他Athelia种的明显不同，偶尔在担子下的木质基质中发现。它们的形状和大小与Fibularhizoctonia sp.相同，也叫白蚁球利用内转录间隔区（ITS）序列进行系统发育分析表明，A. termitophila是Fibularhizoctonia sp.（C）2020的有性型，由Elsevier B.

A new species of Athelia, A. termitophila, from Japan is described and illustrated on the basis of morphological and phylogenetic analyses. Basidiomes of this species are characterized by having hyphae sometimes with clamp connections at the septa, basidia without clamp connections at the basal septa, and ellipsoid to ovoid basidiospores measuring 4.5-6 x 3-4.5 mm. In culture, mycelia produce pale brown, orange-brown to brown, globose sclerotia measuring 0.24-0.41 mm diam. The sclerotia are distinctly different in shape and size from those of other Athelia species, and are occasionally found inside the woody substrate beneath basidiomes. They are identical in shape and size to those of Fibularhizoctonia sp., also known as termite balls. Phylogenetic analysis using internal transcribed spacer (ITS) sequence data revealed that A. termitophila is the teleomorph of Fibularhizoctonia sp.
