| genetic variation within podosphaera tridactyla reveals a paraphyletic species complex with biological specialization towards specific prunus subgenera. | podosphaera tridactyla (ascomycota: erysiphales) is a morphologically variable species occurring on prunus s. lat. in order to assess the genetic variation within this species, the rdna its region was amplified from 29 specimens from a range of prunus species collected in australia, switzerland, and korea. rflp analysis of the pcr products revealed six groups, and a comparison of sequences from representatives of these groups revealed three clades: clade i contained all specimens from prunus sub ... | 2005 | 15912953 |
| caespitotheca gen. nov., an ancestral genus in the erysiphales. | the phylogenetic position of uncinula forestalis within the erysiphales has been inferred from 5.8s, 18s, and 28s rdna sequences. although the appendages of the ascomata are uncinula-like, i.e. unbranched with curved-coiled apices, u. forestalis is situated at the very base of the large erysiphales cluster, far from the 'pseudoidium' clade (erysiphe, including microsphaera and uncinula) and separate from the recently introduced basal genus parauncinula. u. forestalis differs morphologically from ... | 2005 | 16175792 |
| biodiversity and new records of microfungi in the ruhrarea (north rhine westfalia), germany. | during our investigations of the microflora in nrw (duisburg, düsseldorf 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 (lév.) vassilkov. on lycium ... | 2009 | 20222564 |
