Abstract
Species of Absidia are distributed widely in the environment, while their diversity is insufficiently studied. Three new species, A. frigida, A. gemella and A. longissima, are proposed herein from Xinjiang and Yunnan in China based on phylogenetic, morphological and physiological evidence. According to maximum likelihood (ML), maximum parsimony (MP) and Bayesian inference (BI) analyses, the phylogenetical results suggest that A. frigida, A. gemella and A. longissima are closely related to A. psychrophilia, A. turgida and A. zonata and A. koreana, respectively, based on ITS and LSU rDNA sequences. Absidia frigida is characterized by a lower growth temperature, which does not grow above 24 °C. It differs from A. psychrophilia by sporangiophores, sporangia, columellae, collars and projections. Absidia gemella is distinguished from A. turgida by hypha, sporangiospores, sporangia, projections and sporangiophores. Absidia longissima is discriminated from A. zonata and A. koreana by sporangiophores, columellae and collars. The three new species are described and illustrated in this article.
