abstract
Two new species of the genusVerruconis,V.hainanensisandV.pseudotricladiata, were described using combined morphological and DNA sequence data. The DNA sequences of respective strains including nuclear ribosomal DNA genes (nuSSU, ITS, nuLSU) and fragments of three protein-coding genes (ACT1, BT2, TEF1) were sequenced and compared with those from closely-related species to generaOchroconisandVerruconis(Family Sympoventuriaceae, Order Venturiales). Morphologically, both species showed typical ampulliform conidiophores and conidiogenous cells, features not seen in other species ofVerruconis. The conidia ofV.hainanensisare fusiform and those ofV.pseudotricladiataare Y or T shaped, similar to old members of a closely-related genusScolecobasidium. The addition of these two new species provides a new perspective on the heterogeneity ofScolecobasidium.
