Diversity of Genus Volvariella in Faizabad district

Faizabad is located at 260 470 N to 260 780 N latitude and 82.080 E to 82.130 E longitude having an average elevation of 97 meters above the sea level. It is situated on the bank of river Ghaghra formally known as Saryu. It lies in transitional zone between central and the tarai region of Eastern Uttar Pradesh which enjoys a climate congenial for the growth of fungi in general and mushrooms in particular. Genus Volvariella belongs to family Pluteaceae of order Agaricales, have been reported from tropical, subtropical, and temperate regions of both the eastern and the western hemispheres. Few surveys were made to explore its biodiversity from different parts of district Faizabad during June-September, 2006-12. Three Volvariella spp. viz., V. volvacea, V. indica and V. bombycina were collected and identified during the study. Among them, V. volvacea was found in abundance in rice fields and exposed paddy straw stocks. Few specimens were also gathered from mango and jamun orchard while few were obtained from decaying wood of Phoenix sylvestris and decomposed saw dust. These were collected in full bloom in sultry weather of late June- mid September. However their existence was also noticed during the later part of September.
