Notes.

Scytalidium lignicola is phylogenetically closely related to S. auriculariicola and S. philadelphianum (Figs 1 View Figure 1 , 2 View Figure 2 ). The distinctions between S. lignicola and S. auriculariicola are provided in the notes for S. auriculariicola . Morphologically, S. lignicola differs from S. philadelphianum by not producing conidia and by having chlamydospore-like cells swollen up to 7 µm wide ( Pesante 1957; Crous et al. 2022). Furthermore, based on a pairwise comparison of ITS, S. lignicola (ex-type UAMH 1502 ) differs from S. philadelphianum (ex-type CPC 40793 ) in 5.8 % (34 / 580 bp, 14 gaps) in the ITS. Scytalidium lignicola acts as a saprotrophic opportunist in wood, soil, and compost but can shift to a pathogenic mode of life, causing infections in humans ( Dickinson et al. 1983; De Gannes et al. 2013). Notably, as a soil-borne pathogen, Scytalidium lignicola often causes cassava black root rot, which is difficult to control and results in significant losses in cassava production ( Silva et al. 2013).
