Etymology.
In reference to the fungus, which produced falcate conidia.
Diagnosis.
Peglionia falcata is characterised by dry falcate meriform spores (24.1 × 2.9 μm; L / W = 8.005).
Type.
China, Guizhou Province, Guiyang City , 26 ° 57 ' N, 106 ° 72 ' E, from rotten dead branch, 19 July 2023, S. M. Fu, HGUP 23-0013 (holotype), ex-type culture GUCC 23-0042 .
Culture characteristics.
Colonies on PDA, after 8 d, 20–25 mm diam., scarce aerial mycelium, dark brown, white to the periphery, margin entire, reverse dark brown. Occasionally, when a seta bears only two apical branches, one or both can be once forked. Conidiogenous cells polyblastic, obclavate to lageniform, hyaline to subhyaline. Conidia adherent in a continuous white layer on the conidiogenous cells, dry falcate, non-septate, hyaline. Chlamydospores (in culture) in chains, subglobose to irregularly-shaped, subhyaline to brown. Sexual morph not observed. Colonies hypophyllous, scattered, up to 1 mm wide, occasionally larger by confluence, velvety, black when sterile and whitish within when sporulating profusely. Conidiogenous cells obclavate to lageniform, hyaline to subhyaline, distally with a somewhat irregular contour, 5–16.5 × 4–7 µm (x ̄ = 9.8 × 5.3 μm, n = 20). Conidia adherent in a continuous white layer on the conidiogenous cells, falcate, non-septate, hyaline, 18–30 × 2.5–3.5 µm (x ̄ = 24.1 × 2.9 μm, n = 30).
Habit.
On rotten dead branches.
Distribution.
China, Guizhou Province, Guiyang City

China, Guizhou Province, Guiyang City , 26 ° 57 ' N, 106 ° 72 ' E, from rotten dead branch, 19 July 2023, S. M. Fu, HGUP 23-0013 , living culture GUCC 23-0042 , GUCC 23-0043 and GUCC 23-0044 .
Notes.
In morphology, Peglionia falcata differs to P. verticiclada by its larger conidiogenous cells (4–7 μm wide vs. 3–5 μm wide in P. verticiclada ) and larger conidia (18–30 μm vs. 17–22 μm in P. verticiclada ) ( Hernández-Restrepo et al. 2022). The phylogenetic analyses and DNA base differences (Table 2 View Table 2 ) also supported P. falcata as a novel taxon was distinct from P. verticiclada .
