Xenascus

XENASCUS Cookson and Eisenack, 1969, p.7.  Emendations: Yun Hyesu, 1981, p.60; Stover and Helby, 1987a, p.128.  Taxonomic senior synonym: Phoberocysta, by implication in Davey and Verdier (1971, p.27), who considered the "type species" of Xenascus, Xenascus australensis, to be a taxonomic junior synonym of Hystrichosphaera (as Phoberocysta, now Xenascus) ceratioides — however, Lentin and Williams (1973, p.143) retained Xenascus.  Type: Cookson and Eisenack, 1969, figs.1I–J, as Xenascus australensis.
