Biodiversity and new records of microfungi in the Ruhrarea (north Rhine Westfalia), Germany.

摘要

During our investigations of the microflora in NRW (Duisburg, Dusseldorf and Essen incl. the greenhouse of the Botanical Garden) in 2007 and 2008, we were able to collect and identify about 55 species on trees, bushes and ornamental plants as parasites and saprophytes. Some of these species are new for Germany or have been only rarely found until now. Most of the species belong the Ascomycotina, Basidiomycotina and Deuteromycotina for example Arthrocladiella mougeotii (Lev.) Vassilkov. on Lycium barbarum L., Caudospora taleola (Fr.)
