A new species from the fungal genus Tolypocladium (Hypocreales: Ophiocordycipitaceae) that infects Stratiomyidae larva from the genus Hylorops is described: Tolypocladium valdiviae Gallardo-Pillancari, Montalva & González. The description is based on both genomic data and morphological characteristics. The sexual stage of T. valdiviae presents fleshy and visible stromata; unlike Tolypocladium ophioglossoides, it is smaller and emerges directly from its host and resembles Tolypocladium longisegmentis and Tolypocladium capitatum, both of which are parasites of deer truffle fungi of the genus Elaphomyces (Ascomycota: Eurotiales). In the anamorphic state, T. valdiviae presents conidiogenous cells similar in shape and arrangement to those of Tolypocladium inflatum, however T. valdiviae produces larger conidiogenous cells and, occasionally, produces chlamydospores. Phylogenetic evidence suggested that T. valdiviae is in a clade close to T. longisegmentis, T. inflatum and T. ophioglossoides, species also recognized to be parasites of fungi of the genus Elaphomyces. The new species is known so far only from Valdivia, southern Chile.
描述了一种来自枝顶孢属（Hypocreales目：蛇形虫草科）的新物种，它感染了Hylorops属的水虻科幼虫：瓦尔迪维亚枝顶孢（Tolypocladium valdiviae Gallardo-Pillancari, Montalva & González）。该描述基于基因组数据和形态特征。瓦尔迪维亚枝顶孢的有性阶段呈现肉质且可见的子座；与条孢枝顶孢不同，它较小且直接从宿主中长出，类似于长段枝顶孢和头状枝顶孢，这两种都是块菌属（子囊菌门：散囊菌目）鹿块菌真菌的寄生虫。在无性态下，瓦尔迪维亚枝顶孢的产孢细胞在形状和排列上与膨胀枝顶孢相似，然而瓦尔迪维亚枝顶孢产生的产孢细胞更大，且偶尔会产生厚垣孢子。系统发育证据表明，瓦尔迪维亚枝顶孢与长段枝顶孢、膨胀枝顶孢和条孢枝顶孢处于一个进化枝中，这些物种也被认为是块菌属真菌的寄生虫。到目前为止，该新物种仅在智利南部的瓦尔迪维亚被发现。
