本文报道了采自乌孜别克杜松的3个标本中的一个新种-志香丝齿菌（Hyphodontiazixiangii）。本种的特征是一年生，倒卧的担子果，具一个大到齿状的子实梗，一个单丝性的菌丝系统，具钳形连接的生殖菌丝，常见的Lagenocystidia和近头状隔孢囊，和椭圆形到宽椭圆形，薄壁，光滑的担子孢子，大小为4.6-5.5 x 3.3-4 μ m。形态学上，H. zhixiangii与H. alutaria和H.你好H.刺壳属的主要区别在于其具有丘状子实孔和略小的担孢子，大小为4.5-5 x 3-3.5 μ m。H.无隔孢囊虫和长刺虫的区别在于无隔孢囊虫和长刺虫的区别，长刺虫的长度为0.5-2 μ m。在基于ITS的系统发育史中，H. Zhixiangii作为一个独特的谱系嵌套在丝齿菌分支内。三个ITS序列标记为H.阿罗塔没有聚集在一起。由于不知道这些序列中是否有任何一个是从新模式产地瑞典采集的标本中获得的，因此不可能确定哪一个（如果有的话）代表真正的H。你好
Hyphodontia zhixiangii is described as a new species from three Uzbek specimens recently collected on Juniperus. This species is characterized by annual, resupinate basidiocarps with a grandinioid to odontioid hymenophore, a monomitic hyphal system with clamp-connected generative hyphae, frequent lagenocystidia and subcapitate septocystidia, and ellipsoid to broadly ellipsoid, thin-walled, smooth basidiospores measuring 4.6-5.5 x 3.3-4 mu m. Morphologically, H. zhixiangii resembles H. alutaria and H. arguta. H. alutaria differs mainly in its colliculose hymenophore and slightly smaller basidiospores measuring 4.5-5 x 3-3.5 mu m. H. arguta differs in the absence of septocystidia and bearing longer aculei measuring 0.5-2 mu m in length. In the ITS-based phylogeny, H. zhixiangii nested within the Hyphodontia clade as a distinct lineage. Three ITS sequences labeled as H. arguta did not cluster together. As it is not known if any of these sequences were obtained from specimens collected in Sweden, the neotype locality, it is impossible to decide which one, if any, represents the genuine H. arguta.
