Erysiphe acantholimonis

The fungus forms thin, white irregular patches on the leaves of its host. Erysiphe acantholimonis, like most Erysiphaceae, is highly host-specific and infects only Acantholimon.^[1]

The fungus was formally described in 2016 by J.G. Song, B. Xu and H.D. Shin. The species epithet refers to the host genus, Acantholimon.^[1] The type specimen was collected in China on Acantholimon hedinii. Braun and Cook (2012) treated Erysiphe communis f. acantholimonis Koshk., described from Turkmenistan on Acantholimon avenaceum, as a synonym of E. limonii.^[2] This forma might be a synonym of E. acantholinonis, but this requires confirmation by results of sequence analyses.^[3]
