Yang, K. D. Hyde & Y. P. Xiao 2025	<div><p>Ophiocordyceps linyphiidarum Y. Yang, K.D. Hyde &amp; Y.P. Xiao sp. nov. Fig. 2</p><p>Index Fungorum IF 904156, Facesoffungi FoF 17626</p><p>Etymology:— linyphiidarum refers to its host in the arachnid family Linyphiidae .</p><p>Sexual morph: undetermined. Asexual morph: Hymenostilbe -like. Synnemata 2–7 mm long, 0.3–0.5 mm wide, arising from the abdomen of the host spider; multiple, cylindrical, white to cream when fresh, light greyish-brown to pale yellow when dried, smooth, lacking an enlarged globose fertile head at the apex. Phialides along synnemata, arranged in clusters of 2–3, sharing a common base, stout, protuberant, hyaline, polyblastic, clavate or cylindrical, apically crowned with denticles 16.5–22.7 × 2.2–3.8 µm (x = 19.6 × 3.0 µm, n = 60). Conidia smooth-walled, hyaline, one-celled, long-obovoid to ellipsoidal or elongate-ellipsoidal, with slightly rounded ends, some appear slightly fusiform or curved, 6.5–8.6 × 2.3–3.2 μm (x = 7.6 × 2.7 µm, n = 60).</p><p>Material examined:— CHINA.

Yuanpin Xiao, LPS05 (HKAS 132260) .</p><p>Notes:— Phylogenetic analysis based on the combined dataset of SSU, LSU, ITS, tef-1α, rpb1, and rpb2 genes revealed that our collections form a distinct branch and are sister to the clade comprising Ophiocordyceps borealis and O. purpureostromata (Fig. 1). While O. borealis and O. purpureostromata infect larvae of Elateroidea, O. linyphiidarum parasitizes spiders ( Linyphiidae) (Kobayasi &amp; Shimizu 1980, Zha et al. 2021). Ophiocordyceps linyphiidarum is distinct from other species in having slender, white to cream synnemata without an enlarged fertile head, clustered phialides with denticulate apices, and long-obovoid to ellipsoidal conidia. Base differences between O. linyphiidarum and its closest relatives are as follows: compared to O. borealis, 3.8% (37/968) in SSU, 6.7% (56/832) in LSU, 4.6% (22/472) in ITS, and 5.9% (53/896) in tef-1α; and compared to O. purpureostromata, 3.4% (34/978) in SSU, 6.6% (55/833) in LSU, 6.7% (54/802) in tef-1α, and 9.8% (69/698) in rpb1. Both morphological and molecular phylogenetic analyses support that O. linyphiidarum represents a distinct species.</p></div>	https://treatment.plazi.org/id/917787C9FFFB4B5030C5FF196AB5FBA8	Public Domain	No known copyright restrictions apply.
