Phyllactinia taurica
species of fungus
Phyllactinia taurica is a species complex of powdery mildews in the family Erysiphaceae. It is found across the world, where it affects a vast array of different plant families. Phyllactinia taurica is one of the most polyphagous powdery mildew species in the world, although attempts have been made to split it in the past and it may be a complex of many cryptic species on different hosts.
Description
The fungus forms superficial, sometimes quite dense mycelium on both sides of the leaves, stems and inflorescences of its host. The host range of Phyllactinia taurica is incredibly broad and includes genera in Boraginaceae, Brassicaceae, Capparaceae, Euphorbiaceae, Malvaceae, Papaveraceae, Passifloraceae, Pedaliaceae, Ranunculaceae, Rosaceae, Saxifragaceae, Solanaceae, Thymeleaceae and Zygophyllaceae. Phyllactinia taurica sensu lato is known on an even wider range of hosts, but the taxonomic affinity of most records is unclear. Many hosts of P. taurica are grown as crops.
Taxonomy
The fungus was formally described in 1842 by Léveillé with the basionym Erysiphe taurica. The species was transferred to the current genus Phyllactinia in 2025 by Bradshaw et al. The genus of its previous taxonomic placement, Leveillula (named after Léveillé) is now considered conspecific with Phyllactinia.
“Phyllactinia taurica” enters the record as species of fungus. Crown Archives preserves that source wording while asking what Phyllactinia, taurica and species can confirm, complicate or overturn.
Why this record matters
“Phyllactinia taurica” is worth following because a concise public description often conceals a longer documentary argument. Here, Phyllactinia, taurica and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q6534980. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1842 and 2025.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
