Description

Sexual morph: Saprobic. Ascomata ellipsoidal, dark coloured, membranous to coriaceous, immersed, ostiolate. Necks periphysate. Peridium two layers of cells of textura angularis, outer layer of polygonal dark brown, melanised cells with large lumina, inner layer of elongated, polygonal, light brown cells. Asci 8-spored, thin-walled, unitunicate, clavate, persistent, with a long pedicellate. Catenophyses present. Ascospores hyaline, ellipsoidal, thin-walled, 1-septate, not constricted at the septum. Appendages bipolar, at first hamate that deliquesce in water to form thin flat sheets.

NOTES: In a multi-gene phylogeny of Halosphaeriaceae, Halosarpheia kandeliae did not group in the Halosarpheia sensu stricto clade, but was distantly placed in a clade with Halosphaeriopsis medisetigera and Saagaromyces species as sister groups (Sakayaroj et al. 2011). Praelongicaulis kandeliae differs from many Halosarpheia species in having asci with a long drawn out stalk (tail-like), and polar appendages that initially appear amorphous and only later form the characteristic thread-like bipolar appendages. Sakayaroj et al. (2011) did not formally introduce a new genus to accommodate H. kandeliae, and the new genus was introduced by Jones et al. (2015). Genera with bipolar unfurling appendages have evolved many times within the family Halosphaeriaceae and are found in both freshwater and marine habitats (Pang et al. 2003; Pang and Jones 2004).
