Description

Conidiophores 3-5 μm long (x̅ = 2.8 μm, SD = 0.5, n = 20), 19.5-22.5 μm wide (x̅ = 3.6 μm, SD = 0.5, n = 20), micronematous, pale brown, smooth. Conidiogenous cells holoblastic, integrated, terminal, pale brown, cylindrical, smooth-walled. Conidia 49-55 μm long (x̅ = 52 μm, SD = 52.6, n = 20), 19.5-22.5 μm wide (x̅ = 21 μm, SD = 2.4, 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 euseptate, guttulate.

Notes

Dictyocheirospora rotunda , the type species of Dictyocheirospora , was collected on submerged wood in freshwater from Thailand ( Boonmee et al. 2016). It has been reported in Guizhou, China ( Yang et al. 2018). Dictyocheirospora rotunda is similar to D. heptaspora (Garov.) M.J. D'souza, Boonmee & K.D. Hyde in morphology, but the rows of D. rotunda are not separable without manual force, whereas those of D. heptaspora are easily separable ( Boonmee et al. 2016).
