Popis: | Ophiocordyceps xuefengensis T.C. Wen, R.C. Zhu, J.C. Kang & K.D. Hyde, sp. nov. (Fig. 2) MycoBank MB803424 Type: ��� CHINA. Hunan Province: Dongkou County, Xuefeng Mountains, on Phassus nodus in root of living Clerodendrum cyrtophyllum, 20 October 2012, Ru-Cai Zhu 2012 HN 14 (GZUH 2012 HN 14, holotype!). Differs from related Ophiocordyceps species mainly by its long stromata, without a sterile apex, narrow asci, long ascospores and by its occurrence on Phassus nodus in living root or trunk of Clerodendrum cyrtophyllum. Stromata 140���460 mm long, 2���7 mm wide, cylindrical, yellow-brown, 1���4 arising mainly from the head or other part of host; living on larvae of Phassus nodus (Hepialidae) in the trunk or upper root near the soil of Clerodendrum cyrtophyllum (Verbenaceae). Stipe 40���260 mm long, 2���7 mm diam., and sometimes covered with beige, thick, dense, loosely woven mycelium. Fertile part 100���200 mm long �� 2���4 mm diam., cylindrical, yellow-brown. Cells of stromata thin-walled, globose, hyaline, becoming brown-walled towards the outside. Host 60���110 mm long, 7���12 mm wide, yellow-brown to black-brown, with white endosclerotia. Ascomata 416���625 �� 161���318 ��m (x = 520 �� 243, n = 20), superficial, long ovoid, with a basal stipe connected to the stromata. Peridium 20���74 ��m wide (x = 39, n = 20), comprising three layers; hamathecium of paraphyses. Asci 191���392 �� 4.5���8.9 ��m (x = 277 �� 7.5, n = 20), 8-spored, cylindrical, pedicellate not clear, with a 4.2���6.1 ��m wide �� 3.8���5.8 ��m high (x = 5.1 �� 4.7, n = 20) hemiglobose cap. Ascospores 130��� 380 �� 1.4���5.2 ��m (x = 256 �� 3.2, n = 20), fasciculate, thread-like, slender and long, with many septa, not breaking into secondary ascospores. Asexual state: ��� Hirsutella. Etymology: ���Refers to the type collecting site ���Xuefeng Mountains���. Distribution: ���Dongkou County, Hunan Province, China. Host: ���On larvae of Phassus nodus Chu & Wang living in the root or trunk of Clerodendrum cyrtophyllum Turcz. Other material studied (paratypes): ��� CHINA.
