Abstracts |
The studies were conducted to assess the seasonal variation in epigeal fruiting pattern through spring, summer and autumn, and to establish the base-line inventory of macrofungi of Kashmir forests in Western Himalaya. Two forests viz., Gulmarg and Pahalgam of Kashmir, consisting of 9 sites from each forest having either pure or mixed fir (Abies pindrow) stand, were surveyed for epigeal macrofungi in 2008 and 2009. A total of 1,439 sporocarps belonging to 66 macrofungal species (43 genera) were collected during the survey from the selected sites, out of which 36 species were mycorrhizal in nature. Much species diversity was noticed in Russula (13%), Amanita (11%), Suillus (9%) and Hebeloma (7%). The sporocarp production was 14% higher in year 2008 than 2009. Twenty five macrofungal species were observed in both the years whereas 25 species occurred exclusively in 2008 and only 16 macrofungal species exclusively in 2009. Of the 25 species noticed in both the years 60% were mycorrhizal in nature. Twenty seven macrofungal species were noticed in both the forests and 21 species appeared in more than one season. Hitherto unreported macrofungi, Clitocybe eccentrica Peck. and Leucoagaricus nympharum (Kalchbr.) Bon. were new records from India and Panaeolus campanulatus (Bull. ex. Fr.) a new report from Jammu & Kashmir State. The epigeal macrofungal dry biomass yield of 1,800 g ha-1 year-1 was observed from both the forests surveyed and varied from season to season with highest aggregate yield recorded in autumn (921.5 g ha-1) and less in summer (309.5 g ha-1). Gulmarg forest exhibited much diversity in macrofungal biomass than Pahalgam forest. In Gulmarg and Pahalgam forests, an average dry sporocarp biomass of 2,132.5 and 1,467.0 g ha-1, respectively, was recorded from both mixed and pure stands in three seasons with maximum biomass in autumn and minimum in summer. The sporocarp biomass production was more in pure fir forest stands (1,903 g ha-1) than mixed stands (1,697 g ha-1). The study revealed prevalence of great macrofungal diversity and specie richness in Western Himalayan forests and their proper exploration may be of immense future use.
