Description.

Apothecia scattered or in cluster, slightly convex, sessile, hymenium surface light yellow, 0.5-1.5 mm in diam., receptacle surface brownish. Ectal excipulum of textura angularis to textura prismatica, non-gelatinous, lying at a high angle to the outer surface, 30-140 µm thick, inner cells subhyaline to light brown and outer cells brown, 15-30 × 9-14 μm. Medullary excipulum of textura angularis to textura prismatica, 50-150 µm thick, cells hyaline, 5-16 × 4-6 μm. Subhymenium not distinguishable. Hymenium 280-290 µm thick. Asci arising from simple septa, 8-spored, cylindrical, J– in Melzer’s reagent and Lugol’s solution with or without KOH pretreatment, 227-241 × 5-6 μm. Ascospores filiform, hyaline, smooth, multiguttulate, multi-septate, break into several pieces, in fascicle, 192-208 × 1.5-2.0 μm. Paraphyses filiform, slightly enlarged at the apex, hyaline, branched at upper portion, 3.0-5.0 µm wide at apex and 2.0-2.5 μm wide blow, exceeding the asci by 20-35 μm.

Specimen examined.

CHINA, Beijing, Yunmeng Moutain, 40°33.00 ’’ N, 116°40.80'E, alt. 800 m, on herbaceous stem of unidentified plant submerged in water, 10 July 2016, H.D. Zheng, Z.Q. Zeng, X.C. Wang, K. Chen & Y.B. Zhang 10660 (HMAS 275653).

Notes.

This is the first report of V. flavovirens from China. The fungus was originally described from France and currently known in Denmark, Germany, Madeira, New Zealand, UK and USA ( Korf 1974; Iturriaga 1995; Sandoval-Leiva et al. 2014). The Chinese collection agrees with the description of V. flavovirens by Iturriaga (1995). The ITS sequence of the Chinese specimen shared high similarity (99%) with those of North American and New Zealand materials, and the sequences of materials from different geographic regions formed a strongly supported terminal branch (Fig. 1).
