Erysiphe acantholimonis


Erysiphe acantholimonis is a species of powdery mildew in the family Erysiphaceae. It is found in Asia, where it affects plants in the genus Acantholimon.

Description

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.

Taxonomy

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. The type specimen was collected in China on Acantholimon hedinii. Braun and Cook treated Erysiphe communis f. acantholimonis Koshk., described from Turkmenistan on Acantholimon avenaceum, as a synonym of E. limonii. This forma might be a synonym of E. acantholinonis, but this requires confirmation by results of sequence analyses.
