Two new wood-inhabiting fungi, Mycorrhaphium subadustumsp. nov. and Trullella conifericolasp. nov., are proposed and described from Asia based on ITS, nrLSU and tef1 molecular phylogeny and morphological characteristics. Mycorrhaphium subadustum is characterized by a stipitate basidiocarp, velutinate pileal surface concentrically zoned, hydnoid hymenophore, a dimitic hyphal system in spine trama and monomitic in context, absence of gloeocystidia, presence of cystidioles and the non-amyloid, cylindrical to ellipsoid basidiospores. Trullella conifericola is characterized by a laterally stipitate basidiocarp with flabelliform to semicircular pileus, hirtellous pileal surface with appressed coarse hair and concentrically zoned and sulcate, tiny pores (10–12 per mm), a dimitic hyphal system, absence of any type of cystidia, short clavate basidia and thin-walled, smooth, cylindrical to allantoid basidiospores. Phylogenetic analyses based on a three-marker dataset were performed using maximum likelihood and Bayesian inference methods. The two new species formed isolated lineages with full support in Steccherinaceae. The distinguishing characters of the two new species as well as allied species are discussed, and a key to species of Mycorrhaphium is provided.

多标记系统发育和形态学证据揭示了来自亚洲的 Steccherinaceae（多孔菌目、担子菌门）的两个新种


两种新的木材栖息真菌，Mycorrhaphium subadustumsp。十一月和 Trullella conifericolasp。 11月，是根据ITS、nrLSU和tef1分子系统发育和形态特征从亚洲提出和描述的。 Mycorrhaphium subadustum 的特征是具柄的担子果、绒毛状的绒毛表面同心分区、hydnoid 子囊、脊柱中的二分形菌丝系统和单核体、不存在糖囊、存在胞囊和非淀粉样蛋白、圆柱形至椭圆形担子孢子。 Trullella conifericola 的特征是侧面有柄的担子果，有扇形到半圆形的菌盖，菌毛表面有贴伏的粗毛和同心分区和槽，微小的孔（每毫米 10-12 个），二分形菌丝系统，没有任何类型的孢囊，短棒状担子和薄壁、光滑、圆柱形至尿囊状担子孢子。使用最大似然和贝叶斯推理方法进行基于三标记数据集的系统发育分析。这两个新物种在Steccherinaceae的全力支持下形成了孤立的谱系。讨论了这两个新种及其近缘种的显着特征，并提供了菌丝菌属物种的关键。
