Index Fungorum number: IF556209         Facesoffungi number: FoF05717


Sexual morph: Undetermined. Asexual morph: Coelomycetous. Conidiomata 80–110 µm high, 110–140 µm diam. ( = 126.2 × 99 µm, n = 10), pycnidial, dark brown to black, immersed, slightly raised, solitary to gregarious, uniloculate, globose to subglobose, glabrous, ostiolate, with a minute papilla. Conidiomata walls 8–20 µm wide, slightly thick-walled, of equal thickness, comprising several cell layers of brown, pseudoparenchymatous cells of textura angularis, paler towards the inner layers. Conidiophores arising from the inner cavity, reduced to conidiogenous cells. Conidiogenous cells (3.6–)4–7.5 × 2–5 µm ( = 5.4 × 2.8 µm, n = 30), holoblastic, phialidic, rarely with 1–2 percurrent proliferations, discrete, hyaline, ampulliform to subcylindrical, or obclavate, aseptate, smooth-walled. Conidia (17.5–)20–25 × 3–4 lm ( = 22.1 × 3.9 µm, n = 30), cylindrical to subcylindrical, straight to slightly curved, 4-septate, not constricted at the septa, with longest cell at the second from base, bearing appendages; basal cell 2.5–4 lm long ( = 3.2 µm), obconic, truncate at base, hyaline, thin and smooth-walled, second cell from the base 6.5–8 lm long ( = 7.4 µm), pale yellowish, third cell 4–5.5 lm long ( = 4.8 µm), pale yellowish, fourth cell 4–5.5(–6) µm long (x = 5 µm), pale yellowish, apical cell 2–3(–3.7) µm long ( = 2.9 µm), conical, hyaline and smooth-walled, forming three-branched tubular, flexuous, 10–20 lm long apical appendages; basal appendages 5–6 lm long, single, absent at immature state, tubular, unbranched, centric.


Culture characteristics: Colonies on PDA reaching 38–40 mm diam. after one week at room temperature. Colony dense, irregular in shape, flat, slightly raised, surface smooth, with edge undulate, floccose to fluffy, entire margin, forming black stromatic after 2 months; from above, white yellowish to cream at the margin, grey yellowish to dark yellowish, slightly radiated outwards colony, from below, black; not producing pigmentation on agar medium.


Material examined: CHINA, Yunnan Province, Kumming, Kunming Institute of Botany, on dead leaves of Zea mays L. (Poaceae), 5 November 2015, D.S. Tennakoon, COE002 (KUN-HKAS 102242, holotype), ex-type living culture, KUMCC 18-0178.


GenBank Accession No: ITS = MK353083, LSU =MK353085, SSU = MK353148, RPB2 = MK492668,

TEF1-a = MK492656.


Notes: Phylogenetic analyses of a combined ITS and LSU sequence dataset show that Bartalinia kunmingensis (KUMCC 18-0178) clusters with Bartalinia species and is sister to B. robillardoides Tassi (CBS 122705, ex-epitype strain). A comparison of ITS region shows that B. kunmingensis is not significant different from B. robillardoides (only two differentiated nucleotide bases); however, B. kunmingensis is different from B. robillardoides in 207/890 bp (23.2%) in RPB2 region. We therefore, identify our isolate as a new species which was found from corn (Zea mays) in China. Bartalinia kunmingensis differs from B. robillardoides (CBS H-21728) in having smaller conidiomata and paler yellowish conidia. (Crous et al. 2014a).
