03FE3761E10D1E60D28370BEFD72F814.taxon	description	Description: Asexual morph: Colonies on PDA reaching 7 – 8.5 cm diam. after 7 d at room temperature (28 ˚ C), under 12 hours of light-dark alternation. Mycelium light pink to off-white, filamentous, circular, slightly undulate at edge, whitish, with black clustered fruiting bodies, filiform and fluffy margin, white from above and light yellow from reverse. Conidiomata pycnidial, 100 – 600 µm in diam., globose, solitary, black, semi-immersed on PDA, exuding brown to dark brown mass of conidia. Conidiophores branched or unbranched, hyaline or light brown, thin-walled. Conidiogenous cells discrete, ampuliform to lageniform, hyaline, thin-walled, smooth. Conidia fusiform to clavate, straight to slightly curved, 4 - septate, 21.5 – 29.5 × 6.5 – 9 (x = 25.4 × 7.4 µm), basal cell cylindrical to obconic, hyaline or sometimes pale brown, thin-walled, smooth, 2.5 – 5.5 µm (x = 3.7 µm), the three median cells 14 – 20 µm (x = 17.6 µm), concolourous, dark brown with darker septa, second cell from base 5 – 8 µm (x = 6.4 µm), third cell 3.5 – 6.5 µm (x = 4.9 µm), fourth cell 4.5 – 7 µm (x = 5.8 µm), apical cell 2 – 4.5 µm (x = 3.3 µm), cylindrical to sub-cylindrical, hyaline, with 1 – 3 (mostly 2) tubular apical appendages, arising from the apex of the apical cell each at different points, flexuous, 8 – 18 µm (x = 12.4 µm) long, basal appendage often present, single, tubular, unbranched (or rarely branched), short, 1.5 – 4 µm (x = 2.8 µm) long. Sexual morph: undetermined. Notes: The phylogenetic tree supported GUCC 21599 as sister to P. annellata (NTUCC 17 - 030 T) with high support (Fig. 1). Comparing the two strains there were 11 base pai differences in ITS, one character difference in tub 2, and eight characters differences in tef 1 (TABLE 2). In morphology, Pseudopestalotiopsis celtidis was morphologically similar to P. annellata. However, P. annellata can be distinguished by the different number of apical appendages (2 – 3), longer apical appendages (( 18 –) 22 – 32 (– 35) µm) and longer basal appendages (( 4 –) 5 – 7 (– 8) µm) (Tsai et al. 2021). Thus, P. celtidis is introduced as a new species.	en	Yang, Qi, He, Yu-Ke, Yuan, Jun, Wang, Yong (2022): Two new Pseudopestalotiopsis species isolated from Celtis sinensis and Indocalamus tessellatus plants in southern China.

03FE3761E10C1E62D28376F8FBFBFDEB.taxon	materials_examined	Type. China, Hainan Province, Wanning City, from leaves of Indocalamus tessellatus, 14 November 2020, YK He, HGUP 1072, holotype, ex-type living culture GUCC 21600. Disease symptom: Associated with leaf spots of Indocalamus tessellatus. Leaf spots 12 – 68 mm diam., irregular to subcircular, brown, slightly sunken, scattered. Small auburn spots appeared initially and then gradually enlarge, changing to reddish-brown circular ring spots with a dark mahogany border and jagged edge.	en	Yang, Qi, He, Yu-Ke, Yuan, Jun, Wang, Yong (2022): Two new Pseudopestalotiopsis species isolated from Celtis sinensis and Indocalamus tessellatus plants in southern China.

03FE3761E10C1E62D28376F8FBFBFDEB.taxon	description	Description: Asexual morph: Colonies on PDA reaching 6 – 7 cm in diam. after 7 d at room temperature (28 ˚ C), under 12 hours of light-dark alternation. Mycelium light pink to light yellow, colonies filamentous to circular, slightly undulate at edge, whitish, with clustered black fruiting bodies, obviously filiform and fluffy margin, light pink from above and light yellow from reverse. Conidiomata pycnidial, 200 – 400 μm diam., globose, solitary, black, semiimmersed on PDA, exuding brown to dark brown mass of conidia. Conidiophores often reduced to conidiogenous cell, regularly septate and branched at the base. Conidiogenous cells mostly integrated, ampulliform, cylindrical, or clavate, hyaline, smooth-walled. Conidia fusiform to clavate, straight to slightly curved, 4 - septate, 24 – 31 × 4.5 – 6.5 (x = 27.5 × 5.4 µm), basal cell cylindrical to obconic, hyaline, thin-walled, smooth, 2.5 – 5.5 µm (x = 3.9 µm) long, three median cells 14 – 18.5 µm (x = 16.2 µm) long, concolourous, dark brown with darker septa, second cell from base 4 – 7 µm (x = 5.6 µm) long, third cell 3 – 6 µm (x = 4.4 µm) long, fourth cell 4 – 6.5 µm (x = 5.3 µm) long, apical cell 3.5 – 6.5 µm (x = 4.8 µm) long, cylindrical to sub-cylindrical, hyaline, with 2 – 4 (mostly 3) tubular apical appendages, arising from the apex of the apical cell each at different points, 14 – 28 µm (x = 19.7 µm) long, basal appendage usually present, single, tubular, unbranched, 4 – 6.5 µm (x = 5.1 µm) long. Sexual morph: undetermined. Notes: Pseudopestalotiopsis indocalami (GUCC 21600) formed an independent branch in the phylogeny (Fig. 1) and was related to P. curvatispora (MFLUCC 17 - 1722 T, MFLUCC 17 - 1723, MFLUCC 17 - 1747). Comparing the three gene regions of GUCC 21600 and P. curvatispora there was only one basepair difference in the ITS region, but five in tub 2 and 15 in the tef 1 region (TABLE 2). Pseudopestalotiopsis curvatispora has smaller conidia than P. indocalami (( 18.5 –) 22 – 25 (– 26.5) × (6 –) 6.5 – 7 µm), only 1 – 2 apical appendages and a longer basal appendage (( 5.5 –) 9 – 12 (– 13.5) µm) (Norphanphoun et al. 2019). Thus, P. indocalami is considered to be a novel taxon.	en	Yang, Qi, He, Yu-Ke, Yuan, Jun, Wang, Yong (2022): Two new Pseudopestalotiopsis species isolated from Celtis sinensis and Indocalamus tessellatus plants in southern China.
