Diversity of fungicolous fungi associated with Camarotella spp. (Phyllachorales, Sordariomycetes) on Cocos nucifera in Brazil, including Fusicolla parasitica sp. nov. (Nectriaceae).
Camarotella torrendiella and Camarotella acrocomiae, the causal agents of coconut black leaf spot, are of great economic importance to coconut cultivars. Species of hyperparasites have previously been reported in the stromata of these species, which delay and reduce the viability of the ascospores of these pathogens, demonstrating their bio-control potential. In order to identify and analyse the parasitic species affecting the pathogens that cause coconut black leaf spot, symptomatic leaflets exhibiting parasitized stromata of both C. torrendiella and C. acrocomiae were collected in the states of Pernambuco and Paraíba (Brazil) and the fungi present in the stromata were isolated. The hyperparasites were phylogenetically identified based on different gene regions according to genera and presented in this paper with a detailed taxonomic description as well as their abundance and constancy in the coconut grove. A new species of Fusicolla was described in this study as Fusicolla parasitica sp. nov. Acremonium cavaraeanum presented a new record for the states of Paraíba and Pernambuco. Fusarium pseudocircinatum and Fusarium caatingaense presented the first report of their fungicolous lifestyles, while Purpureocillium lilacinum was for the first time recorded hyperparasitizing a Camarotella spp. causing leaf lesions. This study shows Fusicolla parasitica and Acremonium cavaraeanum as constant and abundant species in the coconut grove, while Fusarium pseudocircinatum and Purpureocillium lilacinum are accessory and common; Fusarium caatingaense was considered rare and accidental.
