摘要：It is important to place asexual fungi in families, orders and classes of Ascomycota and Basidiomycota in order to move towards a natural classification. In this way asexual and sexual fungi can be linked and this reduces redundancy resulting from the dual naming system (Hyde et al. 2011; Wijayawardene et al. 2014). Our work on the phylogeny of asexual fungi (Pratibha & Prabhugaonkar 2015a, 2015b, Pratibha et al. 2014a, 2014b) yielded a rare collection of the monotypic asexual genus Mycosisymbrium , with M. cirrhosum Carris, originally described from dead leaves of Vaccinium macrocarpon from Massachusetts, USA (Carris 1994). The genus is characterized by a discrete aggregates of conidiophores terminating in sterile, filiform appendages and brown, one-septate conidia. There have been no further records of this fungus since it was described. In this study, M. cirrhosum was isolated from leaf litter of Gnetum ula Brongn. from the forests of Valpoi, Goa, India and was subsequently cultured. Single spore cultures readily sporulated. Multi-gene phylogenetic analysis was carried out to confirm the phylogenetic placement of Mycosisymbrium as a well-supported sister genus to Ochroconis and Verruconis in the family Sympoventuriaceae in the order Venturiales
