| Note： |
This fungus differs from three other species on Piper spp. namely C. artanthes P. Hennings (Hedwigia 48:18, 1909) C. piperata Asthana & Mahmud (Mag. Agric. Coil. Nagpur, 21:58, 1947) and Pseudocercospora piperis (Patouillard) Deighton (1976) by its thickened conidial scars and hyaline acicular conidia, and by the distinct circular leaf spots it causes on the host. | |||
