On Vonarxia, Kazulia and other fungi with Stauroconidia
Four monotypic genera have been described for Deuteromycetes with superficial, crustose or pulvinate, setose conidiomata and hyaline, septate stauroconidia consisting of a main axis and 2—3 apical branches. The types of Fumagopsis Spegazzini (1910), Vonarxia Batista & Bezerra (1960) and Kazulia Nag Raj (1977) are specimens collected in South America. All develop superficially on living or decaying leaves. Phalangispora constricta Nawawi & Webster (1982) has been described from a pure culture isolated from conidia collected at Malaya. Fumagopsis trigliphioides Speg. has been redescribed by Van der Aa & Van Oorschot (1985) from the type specimen collected in 1909 in Argentina on leaves of Lucuma neriifolia. It forms a pigmented, setose, superficial mycelium with pustulate or crustose conidiomata covered with dark, thick, apparently aseptate setae. The conidia develop singly on ampulliform or irregular conidiogenous cells with a distinct collar or beak. The conidia are composed of an aseptate or 1-septate main axis and 2—3 apical branches, which are constricted at the septa. The base of the conidia is slightly truncate.
