The families Lasiosphaeridaceae and Zygospermellaceae, erected for only one and two genera, respectively, are also points of contention since they were proposed based on limited taxon sampling and poor taxonomic practices. In the recent phylogenetic studies from Kruys et al. (2015) and Marin-Felix et al. (2020), both clades now considered inde- pendent families by Huang et al. (2021) were clustering to- gether in a well-supported clade. Huang et al. (2021) prema- turely introduced both families since they formed two inde- pendent lineages in their phylogenetic study. However, both families are included in the Schizotheciaceae clade in our Bayesian phylogenetic study (0.97 pp) (Fig. 2). More taxa and sequences should be incorporated in further phylogenetic analyses to verify if the Lasiosphaeridaceae and Zygospermellaceae are two independent lineages or belong to the Schizotheciaceae. For these reasons, we reject these families until more data can be analysed and we refer to both lineages as Lasiosphaeriaceae s. lato.
