title: Siepmannia, a new genus in the Mucoraceae.
abstract: A new genus Siepmannia of the Mucoraceae family is described. Siepmannia pineti sp. nov. and S. lariceti sp. nov. were isolated from forest soils in Poland. The species were differentiated on the basis of morphology and ITS1/2 rDNA sequencing. Siepmannia pineti and S. lariceti are identical in some aspects. Both show distinct morphological dimorphism in culture depending on conditions of growth and exhibit distinct mycotrophism manifested by sporulation in the presence of other fungi. Their morphological elements are minute. The phylogenetic grouping of Siepmannia with Absidia parricia and A. zychae leads to the creation of two new combinations, S. parricida and S. zychae.
