03AA83464804487AFF6BFB64FCD18ADA.taxon	etymology	Etymology: luyashanensis, Luyashan Mountain, referring to the locality where the type specimen was collected. Holotype: China. Shanxi Province, Ningwu County, Qiuqiangou Village, Luyashan Mountain, alt. 2099 m, 25 August 2017, in soil under Picea sp., M. Chen CM 023 (BJTC FAN 764). Ascomata subglobose to irregularly subglobose, usually with some superficial or deep furrows, 9 – 10 × 7 – 8 mm in fresh, reddish brown when fresh, with an obvious apical depression of pale color, surface covered with red brown to dark brown fine warts of 160 – 240 μm wide and 80 – 130 μm high, odor and taste not recorded. Gleba solid, white to yellowish white, with several large white veins radiating from the depression. Peridium 260 – 500 μm thick, two-layered, outer layer 120 – 230 μm thick, pseudoparenchymatous, composed of polygonal cells with 4 - 6 sides, cells 15 – 35 × 12 – 25 μm, walls 1.0 – 2.5 μm thick, the outermost cells reddish-brown, and gradually light-yellow to hyaline towards inner side; inner layer hyaline, 150 – 250 μm thick, composed of interwoven hyphae, that more or less parallel to the surface of peridium, hyphae hyaline, 2.5 – 6.0 μm wide. Paraphyses not well-defined, hyaline, cylindrical, straight or sometimes slightly curved, septate, longer than asci, 2.5 – 5.5 μm wide. Asci irregularly clavate or broadly ellipsoid, with a protruding hump at the apex and a pleurorhynchous base, with a slender-stalk, 35 – 50 μm long, 6.5 – 8.5 μm wide, inamyloid, 8 - spored, 120 – 192 × 32 – 50 μm (including stalk), spores irregularly arranged in ascus. Ascospores ellipsoid, smooth, hyaline, inamyloid, 24.5 – 30.8 × 15.5 – 21.5 μm (av. 27.5 × 18.5 μm), Q (L / I) = 1.40 – 1.67 (Qm = 1.54) (n = 30), usually containing one large oil drop and several small droplets. Other materials examined: China. Shanxi Province, Ningwu County, Qiuqiangou Village, Luyashan Mountain, alt. 2026 m, 12 October 2017, in soil under Picea sp., X. Y. Yan YXY 103 (BJTC FAN 1030); ibid., 6 August 1987, in soil under Picea wilsonii Mast., K. Tao MHSU 1730 (HMAS 96698). Note: Barssia luyashanensis was characterized by its reddish brown ascomata covered with fine warts, and solid gleba without chambers. Barssia gunerii, B. hellenica and B. maroccana were similar in appearance of ascomata, but B. gunerii is separated by its subglobose to ovoid ascospores and gleba with irregularly sinuous, labyrinth-like veins (Doğan et al. 2018), B. hellenica by its ovoid ascospores (Kaounas et al. 2015), and B. maroccana by its pale pinkish gleba frequently presenting small labyrinth-like cavities and well-defined sinuous veins, and large ascospores (29 – 36 × 16 – 22 μm, Crous et al. 2014). Another new species B. guozigouensis in this paper was also similar to, but it was distinguished from B. luyashanensis by its distinctly warty ascomata and gleba with small chambers. Also, DNA analysis showed that B. guozigouensis shared less than 94.9 % similarity in ITS sequence with B. luyashanensis. The phylogenetic tree based on ITS and nrLSU sequences indicated that B. guozigouensis and B. luyashanensis each formed a terminal branch (Figs 1, 2) with strong statistic support.	en	Xu, Yu-Yan, Guo, Li-Jie, Li, Ting, Fan, Li (2018): Two new species of Barssia from China.

03AA83464807487AFF6BFE4EFD7C8E82.taxon	etymology	Etymology: guozigouensis, Guozigou, fruit-valley, referring to locality where the type specimen was collected. Holotype: China. Xinjiang Autonomous Region, Huocheng County, Guozigou Forest Park, alt. 1800 m, in soil under Picea schrenkiana Fisch. & C. A. Mey., 11 August 2003, W. P. Wu & M. S. Song 060 (HMAS 97107). Ascomata subglobose to irregularly globose, usually with some superficial or deep furrows, 4 – 16 × 4 – 14 mm in dry, brown to red brown, with an pale color apical depression, surface covered with distinctly pyramidal or round red brown warts of 200 – 260 μm wide and 100 – 140 μm high, odor and taste not recorded. Gleba whitish to yellow white at maturity, solid, marbled with large white vines radiating from apical depression, scattered with some small and irregular chambers. Peridium 250 – 450 μm thick, two-layered, outer layer 100 – 160 μm thick, pseudoparenchymatous, composed of polygonal cells with 4 - 6 sides, cells 15 – 30 × 10 – 20 μm, walls 1 – 2 μm thick, the ourtemost cells reddish-brown, and gradually light-yellow to nearly hyaline towards inner side; inner layer near hyaline, 150 – 250 μm thick, composed of interwoven hyphae, that more or less parallel to the surface of peridium, hyphae hyaline, 2 – 5 μm wide. Paraphyses not well-defined, hyaline, cylindrical, straight or sometimes slightly curved, septate, longer than asci, 2.0 – 5.0 μm wide. Asci irregularly clavate or broadly ellipsoid, with a protruding hump at the apex and a pleurorhynchous base, with a slender-stalk, 45 – 60 μm long, 5.5 – 8.5 μm wide, inamyloid, 8 - spored, 140 – 205 × 30 – 48 μm (including stalk), spores irregularly arranged in ascus. Ascospores ellipsoid, smooth, hyaline, inamyloid, 23.0 – 28.5 × 13.5 – 19.0 μm (av. 25.0 × 16.0 μm), Q (L / I) = 1.35 – 1.75 (Qm = 1.60) (n = 30), usually containing one large oil drop that almost occupied the entire spore. Other materials examined: China. Xinjiang Autonomous Region, Huocheng County, Guozigou Forest Park, alt. 1800 m, in soil under Picea schrenkiana Fisch. & C. A. Mey., 11 August 2003, M. S. Song 067 (HMAS 97104); ibid., M. S. Song & X. Z. Liu 070 (HMAS 97119); ibid., M. S. Song & X. Q. Zhang 064 (HMAS 97114); ibid., M. S. Song & W. P. Wu 056 (HMAS 97128); ibid., M. S. Song 062 (HMAS 97131). Note: Barssia guozigouensis is diagnosed by its distinctly warty ascomata and solid gleba scattered with some small and irregular chambers. Phylogenetically, it was closely related to B. luyashanensis (Figs 1, 2), but the latter differs in its ascomata with fine warts and gleba without chambers. Moreover, the ascospores of B. luyashanensis are larger (24.5 – 30.8 × 15.5 – 21.5 μm). The North African species B. maroccana is similar to B. guozigouensis in shape of ascospores, but differs in size (29 – 36 × 16 – 22 μm).	en	Xu, Yu-Yan, Guo, Li-Jie, Li, Ting, Fan, Li (2018): Two new species of Barssia from China.
