Three new β‐resorcylic acid lactones (RALs), paecilomycins G–I (1–3), and eight known compounds, aigialomycins B–D (4–6), 1′,2′‐epoxy aigialomycin D (7), zearalenone (8), 7′‐dehydrozearalenone (9), and trans‐7′,8′‐dehydrozearalenol (10), antibiotic LL‐Z1640‐1 (11), were isolated from the mycelial solid culture of Paecilomyces sp. SC0924. Their structures were established by spectroscopic methods and
