Scytalidium philadelphianum Crous & Jurjevic

11.Scytalidium philadelphianumCrous & Jurjević, Fungal Syst. Evol. 10: 84 (2022) Description and illustration. Crous et al. (2022). Notes. Scytalidium philadelphianum was initially isolated from compressed air in a factory located in Philadelphia, Pennsylvania, USA (Crous et al. 2022). Scytalidium philadelphianum is phylogenetically closely related to S. auriculariicola and S. lignicola (Figs 1, 2). The distinctions between S. philadelphianum and S. auriculariicola are provided in the notes for S. auriculariicola, while the distinctions between S. philadelphianum and S. lignicola are provided in the notes for S. lignicola. Notably, Ringhofer et al. (2025) obtained the strain UTHSCSA DI 24-300 from urine and intervertebral disc aspirate cultures of a 3 - year-old male Belgian Malinois presenting with progressive hindlimb weakness. The isolate was identified as S. philadelphianum based on 100 % similarity of its ITS with that of ex-type strain CPC 40793.
