Importance and distribution
Rubroshiraia is important in medical industry as it produces hypocrellin A which is utilized as potent therapeutic agents for vascular-capillary diseases or skin diseases (Zhou et al. 2009) and hypocrellin B used as an anti-fungal agent and as photosensitizer for photodynamic therapy of cancer. Hypocrellin B also exhibit antimicrobial and antileishmanial activities (Ma et al. 2004). Rubroshiraia comprises only one species known on living branches of Fargesia spathacea (Poaceae) in Asia (China (Yunnan)).
