Description

Conidiophores 211-345.6 μm long (x̅ = 52.3 μm, SD = 52.3 n = 20), 4.4-9.5 µm wide (x̅ = 7.1 μm, SD = 2.1, n = 20), unbranched, erect, straight, attenuated, distinctly 5-8-septate, thick-walled, medium yellowish-brown, uniform in colour. Conidiogenous cells 120-280 μm long (x̅ = 199.1 μm, SD = 52.9, n = 20), 10-12 µm wide (x̅ = 10.8 μm, SD = 1.8, n = 20), integrated, polytretic with pores 0.8-1 μm diam., terminal and intercalary. Conidia 49-55 μm long (x̅ = 52 μm, SD = 5.2, n = 20), 19.5-22.5 μm wide (x̅ = 21 μm, SD = 3, n = 20), solitary, acrogenous, cheiroid, pale brown to brown, consisting of 5-7 rows of cells, rows digitate, cylindrical, inwardly curved at the tip, arising from a basal cell, without appendages, with each row composed of 8-12 cells, euseptate, guttulate, slightly constricted at septa.

Notes

Diplococcium dendrocalami was firstly introduced in the culms of Dendrocalamus sp. in the Philippines ( Goh et al. 1998) and later was found in Chongqing, China ( Xia et al. 2017). Diplococcium dendrocalami is similar to D. clavariarum (Desm.) Hol.-Jech in morphology, but the conidiophores of D. clavariarum are branched and slender (10-12 µm vs. 3.5-6 µm) ( Goh et al. 1998).
