Camposporium appendiculatum D.F. Bao, Z.L. Luo, K.D. Hyde & H.Y. Su
Index Fungorum number:
IF557026; Facesoffungi number: FoF 07064

Etymology: Referring to the apendages of this fungus.

Holotype: DLU 1234

 

Saprobic on submerged decaying wood in freshwater. Sexual morph: Undetermined. Asexual morph: Colonies on substratum effuse, superficial, black. Mycelium immersed, composed of brown, branched, smooth hyphae. Conidiophores micronematous, mononematous, very short, simple, unbranched, flexuous, pale brown to subhyaline, smooth. Conidiogenous cells mono- or polyblastic, terminal, integrated, denticulate, subhyaline. Conidia 107–119 μm long ( = 113.2 μm, SD = 6.1, n = 30), 9.5–11.5 μm wide ( = 10.4 μm, SD = 1, n = 30), solitary, cylindrical, elongate, 10–13-septate, pale brown at middle cells, hyaline at both the end cells, truncate at both of ends, the apex with a filiform, septate, hyaline apical appendage, 72–114 μm long (x̄ = 107.8 μm, SD = 35.9, n = 25), 3.5–4.8 μm wide (= 4.2 μm, SD = 0.6, n = 25), smooth. (Descriptions from Hyde et al. 2020)

 

Culture characteristics: Conidia germinating on PDA within 24 h. Colonies on PDA at room temperature reaching 2.5 cm diam. in 3 weeks, mycelium pale brown to greyish brown after 3 weeks, composed of pale brown to brown, septate, smooth hyphae.

 

Material examined: CHINA, Yunnan Province, saprobic on submerged decaying wood in Lancang River, December 2016, Z.L. Luo, 2L H 6–3–2, S-1234 (DLU 1234, holotype), ex-type living culture, DLUCC 1234.

 

GenBank numbers: ITS = MN758890, LSU = MN759021, SSU = MN758956, TEF1-α = MN784094.

 

Notes: Morphologically, Camposporium appendiculatum is similar to C. cambrense S. Hughes in having short, simple, unbranched conidiophores, mono- or polyblastic, terminal, integrated conidiogenous cells and cylindrical, elongate, septate conidia with a single appendage at apex. However, C. appendiculatum has 10–13-septate conidia with truncate at both ends, whereas C. cambrense has 3–15-septate conidia, rounded at apex and truncate base. Phylogenetically, C. appendiculatum is not close to C. cambrense, rather it clusters with C. multiseptatum and is sister to C. lycopodiellae (≡ Fusiconidium lycopodiellae) with a strong statistical support. (Notes from Hyde et al. 2020)
