Dingleyomyces P. R. Johnst. & D. C. Park 2023

Dingleyomyces P. R. Johnst. & D. C. Park 2023. Notes. Dingleyomyces lloydii (synonym: Ophionectria lloydii) is an endemic New Zealand fungicolous fungus that parasitizes the stromata of O. robertsii and O. hauturu. Initially described invalidly as Ophionectria cordyceps, it was later validly published as Ophionectria lloydii (Mains 1958) and subsequently recombined as Torrubiella lloydii (Rossman 1977). However, molecular phylogenetic analyses revealed Torrubiella to be polyphyletic, leading to its taxonomic abandonment (Kepler et al. 2017). Johnston et al. (2023) established a new genus, Dingleyomyces, to accommodate this species based on integrative morphological and phylogenetic evidence. The type species is characterized by small perithecial clusters forming on reduced, non-stipitate stromata. The asexual morph is characterized by conidiophores arising from hyphae, typically bearing two phialides with swollen bases and tapering necks. Conidia are cylindric, straight, and aseptate. In this study, we introduce Dingleyomyces yunnanensis as a new species.
