Generic description
Habitat terrestrial, hemibiotrophic or parasitic. Ascomata
small- to medium-sized, scattered, immersed, erumpent to
nearly superficial, papillate, ostiolate. Peridium thin, composed
of two cells types, outer cells of thick walled and
textura angularis, inner cells thin-walled, yellow. Hamathecium
of dense, long and thin pseudoparaphyses. Asci (4-)
8-spored, bitunicate, fissitunicate dehiscence not observed,
broadly cylindrical to cylindrical, with a short,
furcate pedicel and an ocular chamber. Ascospores
fusoid to broadly fusoid, pale brown, septate, sometimes
with one or two vertical septa in the middle cells, constricted
at the septa.
