Similar isolates to one of these species were also collected in the Western Cape from Protea infructescences. These strains were compared morphologically to known species of Penicillium, but could not be identified using previously published keys. Morphologically, these strains belong to the subgenus Biverticillium. They are distinguished by strongly funiculose colonies covered by glutinous exudates and conidiophores having thin acerose phialides (8.5?10[?12] ? 2.0?2.5 μm) giving rise to chains of subspheroid to ellipsoidal conidia (2.5?3.0 ? 1.5?2.5 μm). Characteristically short (100?150[?250] μm) determinate synnema are produced in culture after prolonged incubation with much longer synnema produced in nature. Based on differences in morphology and molecular characters, the strains are described here as Penicillium ramulosum sp. nov.} }
