Acrodictys micheliae and Dictyosporium manglietiae, two new anamorphic fungi from woody litter of Magnoliaceae in northern Thailand

Abstract

Acrodictys micheliae sp. nov. and Dictyosporium manglietiae sp. nov. are described from dead woody litter of Michelia baillonii and Manglietia garrettii, respectively, collected in Doi Suthep-Pui National Park, Thailand. The new fungi are distinctive and readily separated from those already described in the two genera. Acrodictys micheliae has cylindric-ovoid conidia that are similar in shape to A. septosporioides but smaller in size. Dictyosporium manglietiae is distinct from other species in that the conidia have a hyaline, fusoid to cylindrical appendage produced from the basal cell of the outer row of cells. The new taxa are described and illustrated, and compared with similar species. © 2006 Adac. Tous droits réservés.
