Abstract

The Golovinomyces biocellatus complex consists of powdery mildew (Erysiphales) species restricted to hosts of the family Lamiaceae. Previous authors used minor morphological features of the teleomorph and host range data to split the complex. The data, however, were not sufficient to define a convincing species concept. Our taxonomic study is based on molecular phylogenetic and anamorph morphology data. For morphological studies mainly features of the asexual morph (condiophores, conidia, germination patterns) were studied using light and the scanning electron microscopy. Detailed line drawings of anamorph features are provided. For the phylogenetic analysis two markers (rDNA: ITS, LSU) of 64 specimens were applied. The phylogeny resulted in two major clades. Clade I consists of specimens with Lamiaceae hosts and three specimens of Verbena. Clade II consists of two sister groups, the first (IIa) with Salvia spp. and the second (IIb) with Lycopus europaeus (the type host G. biocellatus) and Glechoma. Clade I, IIb and two subclades of IIa with Salvia hosts are characterized by specific morphological traits (differences in conidiophore length, conidial shape, width and germination patterns). Based on these data we suggest to consider specimens of clade I (including specimens on Verbena), IIb and the two subclades of IIa as distinct species, namely G. monardae, G. biocellatus, G. salviae and G. neosalviae sp. nov. A key for identification of species based on anamorph features is provided. The results are discussed with respect to host range, jumps, co-evolutionary aspects and distribution patterns.
