Inflatispora pseudostromatica Y. Zhang ter, J. Fourn. & K. D. Hyde

Notes.

When Tanaka et al. (2015) conducted a revision of the Massarineae , Inflatispora pseudostromatica clustered with Monodictys capensis (now synonymized to Pleomonodictys capensis, Hernández-Restrepo et al. 2017 ) in a clade which was considered as incertae sedis. When the second taxon, I. caryotae was introduced, it was sister to I. pseudostromatica , and together both species clustered with M. capensis and Asteromassaria pulchra (fig. 39 in Tibpromma et al. 2017). None of these taxa had any familial placement and thus, Inflatispora was referred to Massarineae incertae sedis ( Tibpromma et al. 2017). At the same time, in the phylogenetic analyses conducted by Hernández-Restrepo et al. (2017), Inflatispora ( I. pseudostromatica ) grouped with taxa of the novel genus Pleomonodictys ( Pleomonodictys capensis and Pl. descalsii ) described in that study, and those of Bactrodesmium ( B. cubense ), Clypeoloculus ( C. akitaensis ) and Morosphaeria ( M. velatispora ). However, Pleomonodictys was placed in the new family Pleomonodictydaceae , while the other genera were reported as incertae sedis ( Hernández-Restrepo et al. 2017). Later, when Jayasiri et al. (2019) introduced Pleohelicoon in Pleomonodictydaceae , Inflatispora clustered with Pleohelicoon and Pleomonodictys in a clade, where it formed a distinct basal lineage to the two genera with low statistical support and was still considered as incertae sedis taxon. In the present study Inflatispora clusters in Pleomonodictydaceae with 99 % ML BS, 1.00 BYPP statistical support (Fig. 1 ). Inflatispora resembles (in its sexual morph) Robiniigena hyalinospora gen. et sp. nov. in Pleomonodictydaceae and is accepted in the family based on morpho-phylogenetic evidence.

Figures

Figure 1. Phylogram generated from maximum likelihood analysis based on SSU – LSU – ITS – tef 1 - α – rpb 2 combined dataset for the families in Massarineae. The evolutionary model GTR + I + G was applied as the best-fit model for all the loci. The BYPP analysis was run for 3 million generations. The tree is rooted with Leptosphaeria doliolum (CBS 505.75) and Stemphylium vesicarium (CBS 191.86). Maximum likelihood bootstrap, ML BS (≥ 60 %), and BYPP (≥ 0.95) supports are respectively shown above or below the branches. Type strains are in bold black, and the novel taxon is in bold red. (-) indicate ML BS < 60 % or BYPP < 0.95.
