Camposporium multiseptatum D.F. Bao, Z.L. Luo, K.D. Hyde & H.Y. Su, in Hyde et al., Fungal Diversity 100: 82 (2020)

Index Fungorum number: 557025            Facesoffungi number: 07063


Sexual morph: Undetermined. Asexual morph: Colonies on substratum effuse, superficial, black. Mycelium immersed, composed of hyaline, branched, smooth hyphae. Conidiophores micronematous, mononematous, short, simple, unbranched, flexuous, pale brown to subhyaline, smooth. Conidiogenous cells mono- or polyblastic, terminal, determinate, subhyaline. Conidia 97–111 μm long (x̄ = 103.8 μm, SD = 7.2, n = 30), 9–11 μm wide (x̄ = 9.8 μm, SD = 0.8, n = 30), fusiform to cylindrical, truncate at both of the ends, 10–13-septate, dark brown at central cells, paler both of end cells, with a short, septate, subhyaline, single appendage at apex, 11–17 μm long (x̄ = 13.8 μm, SD = 3, n = 15),

3.5–4.7 μm wide (x̄ = 4.1 μm, SD = 0.6, n = 15), smooth.


Culture characteristics: Conidia germinating on PDA within 24 h. Colonies on MEA at room temperature reaching 3.3 cm diam. in 3 weeks, mycelium grayish brown to dark brown after 4 weeks, composed brown to dark brown, septate, smooth hyphae.



Material examined: CHINA, Yunnan Province, saprobic on submerged decaying wood in Dulong River, October 2016, Z.L. Lou, 2D H 1–4–2, S-792 (DLU 792, holotype), ex-type living culture, DLUCC 792.


GenBank Accession No: ITS: M N758889, LSU: MN759020, SSU: MN758955, TEF1-a: MN784093


Notes: Camposporium multiseptatum is phylogenetically close to C. appendiculatum. Morphologically, C. multiseptatum is similar to C. appendiculatum in having short, simple conidiophores, mono- or polyblastic, terminal, determinate conidiogenous cells and cylindrical, septate conidia, truncate at both ends, with a single appendage at apex. However, C. multiseptatum differs from C. appendiculatum in having shorter appendage (11–17 μm versus 72–114 μm). Moreover, we compared the base pairs of TEF1-α gene regions, and there are 17 base pairs that were different in 875 nucleotides of the TEF1-α region. These results strongly support our isolate to be a new species.
