This paper reports the first work on the successful cultivation of Pycnoporus sanguineus, wild wood-rotting basidiomycetes from the Philippines. This bright red-orange, thin fan-like shaped mushroom growing on the dead hardwood was collected and was subjected to tissue culture. The mycelia favorably grew on malt extract agar (MEA) (dehydrated culture medium) and potato broth sucrose agar (indigenous culture medium) with colony diameters of 77.50 mm and 82.00 mm after 4 days of incubation, respectively. Among spawn materials used, both sorghum seeds and cracked corn recorded the short period of incubation (10 days) and very thick mycelia. The highest yield of fruiting body (17.07 g/bag) and biological efficiency (BE) (3.41%) was recorded in 8 parts rice straw + 2 parts sawdust formulation. The low BE obtained in the present work suggests optimization and enriched cultivation studies to increase the bio-efficiency.
Key words: Pycnoporus sanguineus, secondary mycelia, culture conditions, biological efficiency.
