Notes – the ascomycetous genus Scytalidium is a member of the family Chaetomiaceae within the class Leotiomycetes (Crous et al. 2023). Scytalidium species have also been reported from various habitats as soil, air, decaying plant material, and termite gut (Ogel et al. 2001). They have been known to play an important ecological role in breaking down organic matter, while some engage in parasitic or mutualistic relationships with other organisms. Scytalidium assmuthi, a newly isolated species, was isolated from the gut of an Odontotermes assmuthi termite (Fig. 1).
Figure 1 – The placement of Scytalidium assmuthi using a maximum likelihood (ML) analysis of the concatenated gene sequence of ITS and LSU (D1/D2 domain) rRNA region using the TNe+G4 chosen according to the Bayesian Information Criterion model in IQ-TREE v. 1.6.12 (Nguyen et al. 2015). The scale bar indicates the expected number of substitutions per site. The numbers provided on branches are frequencies with which a given branch appeared in 1000 bootstrap replications. The tree was rooted with Dermea acerina CBS 161.38 and Dermea cerasi MFLU 16-0929. The new species proposed in the present study is in bold and highlighted text
