Abstract: Typical Talaromyces ascomata were observed on dry Quercus suber leaf litter amongst the characteristic synnemata of Penicillium aureocephalum, and they appear to represent the sexual state of the latter species. The species is a synonym of the older Lasioderma flavovirens, and we propose the new combination Talaromyces flavovirens. Lectotype and epitype specimens are designated for this name. The defining characters of the asexual state include yellow, short-stalked, mycetozoan-like synnemata with an unusual, almost closed terminal head of penicillate conidiophores intermixed with sinuous hyphae, and dark green conidia. Ascomata could not be induced in culture, but PCR amplifications of mating-type genes indicate the species is heterothallic. In nature, ascocarp initials appear to be antheridia coiled around clavate ascogonia, similar to those of T. flavus, and the thick-walled, spiny ascospores are also similar to those of T. flavus. ITS barcodes and β-tubulin sequences place T. flavovirens in a clade with T. apiculatus, T. flavus, T. funiculosus, T. galapagensis, T. pinophilus, T. macrosporus, and seven other species.
