Phellibaumins are hispidin derivatives isolated from the fungus "Phellinus". Five such derivatives have been identified, designated as phellibaumins A through E. Phellibaumins A and B are classified as pyranones, while phellibaumins C, D, and E are classified as styrylpyranones. 
Phellibaumin A was also identified as being produced by the fungus "Inonotus hispidus," and phellibaumins B and C were identified in "Sanghuangporus vaninii". Phellibaumin E is of interest to medical researchers due to potential anti-dementia effects.
