Forty eight soil samples were collected from Wet evergreen
forest of Tamil Nadu, Southern India; the fungi from these
soil samples were isolated in (June – July) South West
monsoon and (November – December) North East resting monsoon
both seasons. About different species belongs to various
groups viz; Ascomycotina, Zygomycotina and Deuteromycotina
were identified with the help of relevant literatures. A
total of 76 taxa belonging to 25 genera were isolated, these
include one species of Acomycetes, one species of
Coelomycetes five species of Zygomycetes and remaining
species were Deuteromycetes. Twenty one species of
Penicillium and 14 species of Aspergillus were
also recorded from both seasons. None of the basidiomycetes
could be isolated from these soils in spite of our best
efforts. The diversity indices of forest soil fungi over the
two seasons were 2.953, 2.699 (Shannon-Weinner), 0.9033,
0.8491 (Simpson index) and 0.2219, 0.3485 (Fishers’s alpha),
respectively. The soil nutrients were also analyzed for
montane wet temperate forest. The macro nutrients such as N,
P, K content were rich in after the raining season and
organic content of natural soil was also increased.
Key words:
