Species in the order Melanosporales (comprises the family Ceratostomataceae) are characterised by the production of usually translucent ascomata, unitunicate asci, and unicellular, pigmented ascospores with germ pores or germ slits (Marin-Felix et al. 2018). Thielavia basicola produces translucent ascomata, unitunicate asci, and unicellular, pigmented ascospores with a germ pore, fitting in the family Ceratostomataceae. Moreover, most of the species in the Ceratostomataceae are known to be parasitic on or closely associated with other fungi, including basidiomycetes and sexual and asexual reproducing ascomycetes (Jeffries & Young 1994, Harveson 1999, Zhang & Blackwell 2002, Marin-Felix et al. 2018). These data provide robust support for the phylogenetic placement of Th. basicola in the Ceratostomataceae, rather than Chaetomiaceae. As a consequence, the Thielavia species classified in the latter family should be combined in other or new genera.
To better understand the relationship between Podospora anserina and its closely related species, we re-analysed the published sequence data generated by Boucher et al. (2017), including ITS sequences and sequences of three other intergenic loci from different chromosomes (Rchr3, Rchr4 and Rchr6). Single gene trees were constructed based on each locus. ITS failed to distinguish Pod. anserina from Pod. pauciseta, Pod. bellae-mahoneyi and Pod. pseudocomata (Fig. 6A). In contrast, Rchr3 (Fig. 6B), Rchr4 (Fig. 6C) and Rchr6 (Fig. 6D) differentiated all seven species which were accepted by Boucher et al. (2017), and Rchr3 even recognised two subclades within the P. anserina clade.
