Ganoderma lucidum and allied species are widespread and cause white rot diseases on economically important crops, hardwoods and forest trees. An attempt has been made to distinguish G. lucidum complex by cultural characteristics. This study showed that the G. lucidum complex in a native collection is represented by G. lucidum, G. resinaceum, G. tropicum, G. weberianum, and Ganoderma sp. Most of the collections were confined to hardwood and rarely found on palm host. All the five species produced chlamydospores with varying shape and size. Ganoderma resinaceum and G. lucidum had an optimum growth rate at 30-35 °C; the former produced larger chlamydospores in culture than the later. Ganoderma tropicum produced cylindrical chlamydospores and had average growth rate at 20-25 °C. Ganoderma weberianum produced both chlamydospores and gastrospores in cultures with optimum growth rate at 30-35 °C. Ganoderma sp. produced both amyloid and inamyloid chlamydospores in culture and had optimum growth temperature of 20-25 °C. All the eight isolates showed positive reaction to acid aniline test.
