Discussion The. soil freshly worked by the termites has a significantly lower number of spores developing from it than the unworked soil (Tables 5-7-1 and 75-7*n). This could indicate that the presence of naliva with the soil is preventing germination of some spores. The older worked soil has an even lower ntunber of epores present which could be explained by the effects of the saliva on the spores, with a drop in the- ntunber of viable spores rerulting from desiccation and ageing due to spores having been incorrorated for a long time. The numbers obtained from the older worked soil in this experiment are comparable to those obtained from the nest structure (Table 502-7)9 i. e. 17*78 x 103 and 16#46 x 103 colonies per 9 dry weight* comparison of the species composition of the 3 soils (Table 5-7-3) shows that the drop in numbers of fungi from unworked soil to freshly wart-Led soil in not due to a fall in the number of species Isolated. In general the SWNO species are Isolated but in lower numbers in the freshly wortiLed soil, Interestingly, Basidiomycotes such as WO and WG, and the sterile mycelium VPP, increase in number "58 - from the unworked to freshly worked soil* This suggests that they are not being affected by the saliva to the same extent as the Fungi Imperfecti. This might be expected as it is unlikely that the aaliva would adversely affect Terml! ýMces. In the older woriced soil both number3 and species of fungi have declinadq the Aspergilli mostly having disappeared while the Penicillia remain. 5-7-2 IMUDITION OF SPORE GMU41MTIOII 13Y LXMCTS or, FOIDI)STORr.,, FLINGUS C0113 AND TEMIUB. a Methoda In order to determine whether there Is anything present in the foodstoreq : fungus comb or termites preventing Coraination of the sporoa
