Doassinga, a new genus of Doassansiales

摘要

In order to examine the systematic position of Entyloma callitrichis, morphological, ultrastructural and molecular characters of E. callitrichis and some species of the Entylomatales and Doassansiales were studied and compared. It was shown that E.callitrichis (isolated from Callitriche palustris) belongs to the Doassansiaceae, occupying a basal position within this family. In contrast with the other species of Doassansiaceae, the teliospores of E. callitrichis are not arranged in spore balls. Therefore, the new genus Doassinga is proposed to accommodate E. callitrichis (D. callitrichis).
