285B1437CC2ED302398DFBCDFB050FF5.taxon	description	Colonies on PDA, medium dense, irregular, slightly raised, wavy margin, like blooming peony, white at the margin, umber in the centre, reverse white at the margin, light brown in the centre. PDA attaining 69.5 – 72.7 mm in diameter after 7 days (in the darkness, 25 ° C), growth rate 9.9 – 10.3 mm / day. Leaf spots irregular, pale yellow or yellowish-brown. Asexual morph developed on PDA: Hyphomycetous. Conidiomata solitary or aggregated, superficial, subglobose, initially appearing hyaline, becoming dark yellowish-gray with age. Conidiophores smooth, septate, branched. Conidiogenous cells subcylindrical or subglobose, 3.71 – 7.21 × 2.14 – 4.25 μm, mean ± SD = 5.1 ± 0.8 × 3.1 ± 0.4 μm. Conidia pale yellowish brown, smooth, straight or sinuous, apex acute to nearly rounded, 14.20 – 22.92 × 2.51 – 4.11 μm, mean ± SD = 17.8 ± 1.3 × 2.8 ± 0.2 μm (l: w = 6.3). Sexual morph not observed.	en	Wang, Shi, Mu, Tai-Chang, Liu, Rong-Yu, Liu, Shu-Bin, Zhang, Zhao-Xue, Xia, Ji-Wen, Li, Zhuang, Zhang, Xiu-Guo (2022): Coniella castanea sp. nov. on Castanea mollissima from Shandong Province, China.

285B1437CC2ED302398DFBCDFB050FF5.taxon	discussion	Notes. Combined ITS, LSU, RPB 2 and TEF 1 - α gene analysis of this study showed that our isolates (SAUCC 200313, SAUCC 200314) formed an distinct clade with a high support value (99 % / 0.99) (Fig. 1). Coniella castanea differs from C. quercicola by 31 nucleotides (5 / 562 in ITS, 2 / 1172 in LSU, 15 / 768 in RPB 2 and 9 / 333 in TEF 1 - α). Morphologically, our collections differ from C. quercicola in having large conidia (14.20 – 22.92 × 2.51 – 4.11 vs. 13.00 – 19.00 × 2.00 – 3.50 μm) (l: w, 6.3 vs. 5.3), smaller conidiogenous cells (3.71 – 7.21 × 2.14 – 4.25 vs. 8.00 – 16.00 × 1.00 – 2.50 μm) and color of conidiomata (dark yellowish-gray vs. olivaceous to black) (Alvarez et al. 2016). Based on phylogeny, morphology and nucleotide differences, we introduce our isolates as a novel species, Coniella castanea.	en	Wang, Shi, Mu, Tai-Chang, Liu, Rong-Yu, Liu, Shu-Bin, Zhang, Zhao-Xue, Xia, Ji-Wen, Li, Zhuang, Zhang, Xiu-Guo (2022): Coniella castanea sp. nov. on Castanea mollissima from Shandong Province, China.
