The ftmgua combs of Mcrotermes species are covered vith mycelluml
on both tho fresh and old zones, This observation ia borne out on
comparing the Isolation Indices of Tem. jtýonnrces on both vaedia whero
there in no difference in the isolation of Termitomyces from the two
zonex
(Table 5.4.1). The other fungi obtained In the Isolations are
all fungi found in the &oil& and are probably brought In by the
termites* The greatest number of fungal colonies and species were
Isolated from comb of Hicrotermes gD,, R-9 which In found In river1ne
forest at Rabba with vauch more moist Bolls richer in organic matter
than those of the savannas and so a higher number of soil fungi would
be expected*
The use of thO 8016r-tiv4b medium h" again Increased the Isolation
of Terrdt2=ex above that of the'OrdlMrY SP medium, reducing the
number of other funCal species obtained from the leolations. Ilany
