Description

Conidiophores 480-520 μm long (x̅ = 280.6 μm, SD =4 5, n = 20), 2-5 µm wide (x̅ = 3.7 μm, SD = 1.3, n = 20) macronematous, synnematous, erect, septate, smooth, mid-brown to dark brown. Conidiogenous cells 14.5-35.9 μm long (x̅ = 26.6 μm, SD = 4.4, n = 20), 1.6-3.8 μm wide (x̅ = 3.0 μm, SD = 0.6, n = 20) integrated, terminal, polyblastic, pale brown to hyaline, sympodial, splaying out with one to several denticulate conidiogenous cells loci. Conidia 3.5-5.5 μm long (x̅ = 4.5 μm, SD =1.1, n = 20), 2.5-4.8 µm wide (x̅ = 3.5 μm, SD =1.4, n = 20), globose to obovoid, hyaline, smooth-walled, guttulate, aseptate.

Notes

This species was originally discovered on decaying wood in Guizhou Province, China ( Hyde et al. 2018). It is similar to P. clavulata (Grove) E. W. Mason & S. Hughes in conidial shape, but the latter has smaller globose conidia (3.5-5.5 µm vs. 1-2 µm) ( Révay 1985, Hyde et al. 2018).
