Asterostromina Bat. & A.F. Vital, in Batista, Vital & Maia, Revta Biol., Lisb. 1: 116 (1957)
Epiphytes on the upper surface of the leaves, forming blackened circular areas with radiating margins. Superficial hyphae with parallel radiations, with internmittent darker nodes, appressoria not observed. Sexual state: Thyriothecia solitary or scattered, superficial around centre of hyphae group, solitary or scattered, easily removed from host surface, globose to subglobose, comprising brown to dark brown walled cells, rounded at the margin, ostiole centre, with a poorly developed basal layer. Asci not observed in Kalchbr and Cooke (1880). Asexual state: Asterostromina solaris Bat. & A.F. Vital.. Conidophores conical to cylindrical, cupshaped. Conidia (1-)2-septate, constricted and dark at the septa, apical cell rounded and broader than lower cell, sometimes apical cell narrower and broader than lower cell, brown to dark brown (von Arx and Müller 1975).
Notes: Asterodothis was established by Theissen (1912a) in the family Microthyriaceae and has remained monotypic until now. Hosagoudar (2001) placed this genus in the family Asterinaceae based on the radiating stromata, and 4-celled conidia, produced on Oleaceae and Celastraceae leaves. The genus is quite distinct from species of Asterina. Thus we place it in Dothidoemycetes genera incertae sedis, until it can be recollected and sequenced.
Type species: Asterodothis solaris (Kalchbr. & Cooke) Theiss., Annls mycol. 10(2): 179 (1912).
