Index Fungorum number: IF 143146; Facesoffungi number: FoF 12337, Fig. 1654
Description:
Saprobic on host. Sexual morph: Unknown. Asexual morph: Conidiomata 60–75 μm diam., 55–70 μm high, circular to subcircular, grey-brown to brown, surrounded by brown mycelium. Mycelium superficial. Conidiophores 50−80 × 2−4 µm (x̄ = 60.6 × 3.2 µm, n = 10), single or in dense fascicles, arising from the upper cells of an intraepidermal and substomatal, brown stroma, pale brown to brown, simple, rarely branched, thick-walled, irregular in width, attenuated in the upper portion, 2–4-septate. Conidiogenous cells 7−11 × 2−4 µm (x̄ = 8.2 × 2.5 µm, n = 10), intercalary and terminal, proliferating sympodially. Conidia 7.9−9.6 × 3.4−4.3 µm (x̄ = 8.5 × 3.8 µm, n = 10), solitary, hyaline to pale brown, subcylindrical to obclavate, hila thickened, darkened, refractive.
Material examined: The United States, Colorado, Silver Lake, on dead stems, 5 September 1914, Bartholomew (BISH 606514).

Importance and distribution
There are 24 Neopeckia epithets in Index Fungorum (2022), but seven species have been transferred to Byssosphaeria, Herpotrichia and Spinulosphaeria. Neopeckia comprises 17 species known on a range of plants such as Hevea brasiliensis (Euphorbiaceae), Nyssa sp. (Nyssaceae), Robinia pseudoacacia (Fabaceae), Pandanus tectorius (Pandanaceae), Prunus sp. (Rosaceae), Sasa kurilensis (Poaceae), Camellia sinensis (Theaceae), Gliricidia sepium (Fabaceae), Pandanus sp. (Pandanaceae) and Torreya sp. (Taxaceae). Neopeckia is reported from Africa (Ghana), Asia (Indonesia, Japan, Philippines), Europe (Georgia, Poland, Romania, Switzerland, United Kingdom) and the United States (Hawaii).
