[1] The phylogenetic origin of the lineage was placed to various parts of Basidiomycota, but according to the analysis of larger datasets it is a (495-million-years-old) sister group of Agaricomycotina.

[5] Inability to grow without salt is an exception in the fungal kingdom, but is common in halophilic Archaea.

[1] These increase in size almost four-fold when exposed to high salinity, and the cell wall experiences a three-fold thickening.

This results in a substantially decreased functional cell volume and is thought to be one of the halotolerance mechanisms of this species.

[3] Contrary to what was observed for the extremely halotolerant H. werneckii, in W. ichthyophaga there are almost no expansions in metal cation transporter genes and their expression is not salt-responsive.
