First record of Erysiphe quercicola (Ascomycota: Erysiphales) on species of Quercus subgenus Cyclobalanopsis (evergreen oaks, Fagaceae)

Publication date: March 2018 Source:Mycoscience, Volume 59, Issue 2 Author(s): Susumu Takamatsu, Saya Katsuyama, Toshiya Shinoda During the DNA sequence analyses of specimens on Quercus subgenus Cyclobalanopsis deposited as Erysiphe gracilis or Cystotheca wrightii, some specimens exhibited DNA sequences that are different from the sequences of the two species. Based on BLAST search and morphological observations, the true causal agent was identified as E. quercicola. This is the first record of E. quercicola on species of subgenus Cyclobalanopsis. Previous studies revealed that E. quercicola is plurivorous infecting a wide range of tropical fruit trees and woody plants. Further studies are needed to address the question as to why only E. quercicola infect species of subgenus Cyclobalanopsis.
