Distribution
''Clavulina'' species are important primary colonizers of forest litter, and occur immediately after the pre-monsoon showers. Two species of ''Clavulina'' – ''C. coralloides''(known as white or crested coral fungus) and ''C. rugosa'' – have been recorded from the moist-deciduous to evergreen forests of the Western Ghats, Kerala, India.[
