Peace lilies or Spath [Spathiphylllum wallisii Regel.] grown in the garden of Agri-Horticultural Society of India at Alipore road, Kolkata, West Bengal are found to be attacked severely by anthracnose disease. The characteristic symptoms appeared on the underside of the leaves near the leaf margins where necrotic lesions were observed with brown wavy margins and ash coloured centres over which light brown to black, superficial, erumpent acervuli, 271.6 – 467.9 x 198.6 – 312.5µ sized with setae measuring 97.6 – 138.8 x 7.6 – 13.9 µ, 1-2 septate, black with pointed tips were observed. Conidia were single celled, hyaline, cylindrical with both ends rounded, eguttulate, 14.4 – 23.1 x 2.3 – 4.6µ in dimension. On the peptone agar medium (PAM) which had been proven ideal medium for acervuli production and sporulation, the pathogen produced hyaline hyphae, covered 90mm. diameter of Petri plate within 9 days after inoculation with huge production of acervuli and conidia. Hyphae were hyaline, thin, septate and 2.3 – 7.9µ wide. On the PAM medium, acervuli were 498.8 –879.4µ in diameter; setae were numerous, dark black, 1-2 septate, unbranched with pointed tips and 202.1 – 380.3 x 10.9 – 18.8 µ in size. Conidia were hyaline, single celled, eguttulate, cylindrical to rod shaped with both ends rounded, 18.4 – 28.3 x 4.0 – 6.3 µ in size. Pathogenicity test of the isolated fungus had been established under laboratory condition following detached leaf technique. There was no detailed record of work done on anthracnose disease of Spathiphyllum wallisii. The causal anthracnose fungus had been identified as Colletotrichum gloeosporioides, from West Bengal by comparing with morphological descriptions of the Colletotrichum spp. described by Suttons (1980) and Colletotrichum gloeosporioides descriptions given by Saccardo (1884). It was the first record of this pathogen on this host from India as well as from West Bengal.
