15.Scytalidium terrigenumY. S. Jeong, S. Yeol Lee & H. Y. Jung, Mycobiology 53 (3): 297 (2025) Description and illustration. Jeong et al. (2025). Notes. Scytalidium terrigenum was isolated and named by Jeong et al. (2025) from a soil sample collected in Chungcheongnam-do, South Korea. Scytalidium terrigenum is phylogenetically closely related to S. album, S. assmuthi, S. aurantiacum, S. rodionovae, S. circinatum, and S. tongrenense (Figs 1, 2). However, the distinctions between S. terrigenum and S. album, S. assmuthi, S. aurantiacum, S. rodionovae, and S. circinatum are provided in their respective notes. Additionally, S. terrigenum differs from S. tongrenense by its production of hyaline to brown arthroconidia and oval chlamydospore-like cells (Jeong et al. 2025). Furthermore, based on a pairwise comparison of ITS and LSU, S. terrigenum (ex-type KNUF- 23-236) differs from S. tongrenense (ex-type CGMCC 3.28994) by 5.5 % (30 / 544 bp, seven gaps) in the ITS and 2.4 % (22 / 895 bp, five gaps) in the LSU. Notably, S. terrigenum is capable of growing in acidic (pH 4) and low-temperature (10 ° C) environments (Jeong et al. 2025).
