Stoykov, D., Stoyanova, Z. & Alvarado, P. (2024). Report and first molecular data of Alternaria infectoria, Lecanicillium fungicola, Mycogone rosea, Sarocladium strictum and Sepedonum chrysospermum, growing on wild mushrooms in Bulgaria. Bulg. J. Agric. Sci., 30 (Supplement 1), 38–46
Fungicolous fungi are the main group causing diseases on cultivated and wild mushrooms. This study aims to report six taxa growing on decaying mushrooms collected in Bulgaria, and to isolate and characterize five of them with molecular data: Alternaria infectoria on Hortiboletus bubalinus, Hypomyces chrysospermus on Boletus edulis, Lecanicillium fungicola on Lactarius deliciosus, Mycogone rosea on Amanita caesarea, and Sarocladium strictum on Xerocomus subtomentosus. Three of the mushroom hosts are known to be economically important, traditionally gathered by locals in Bulgaria. Amanita caesarea was red-listed in Bulgaria as Vulnerable (VU), and as Least Concern (LC) in the IUCN Red list of threatened species 2019. Additionally, Cladobotryum verticillatum (sexual morph Hypomyces armeniacus) is here reported and described from old and decaying basidiomata of Lactifluus volemus and Russula sp. in Forebalkan, and Lactarius aurantiacus in Vitosha Mt. Six collections were made in coniferous or deciduous habitats, and another was found under Tilia cordata trees. Hypomyces chrysospermus (asexual morph Sepedonium chrysospermum) is reported for the first time on fruit-bodies of Boletus edulis and Xerocomus subtomentosus from Forebalkan, Vitosha and Rhodopi Mts.
