Summary
The fungal composition of soils with an equivalent percentage of carbon levels 2%, 5%, 10% and 20% fromOlea europea,, Citrus sinensis andEucalyptus rostrato leaves was studied after 10, 45 and 120 days using the dilution-plate method. They all induced significant increases in the total count of fungi, but their effect on the individual fungi was selective. The best substrate for the total fungus flora wasCitrus sinensis and the poorest wasOlea europeae leaves.
The best three colonisers (possessing the highest counts), at carbon levels 2%, 5%, 10% and 20% at the end of the experimental periods were, respectively, as follows: forOlea europeae leaves,Scopulariaopsis brevicaulis, Drechslera halodes andCylindrocarpon sp.;Aspergillus quadrilineatus, A. sydowi andCurvularia lunata; A. quadrilineatus, Alternaria alternata andC. lunata andA. quadrilineatus, A. egyptiacus andA. terreus; forCitrus sinensis leaves,A. quadrilineatus, A. fumigatus andS. brumptii; A. fumigatus, A. quadrilineatus andA. versicolor; A. quadrilineatus, A. terreus andS. brumptii; andA. quadrilineatus, A. flavus andA. sydowi; and forEucalyptus rostrata leaves,A. quadrilineatus, Rhizopus stolonifer andA. sydowi; A. quadrilineatus, A. niger andA. terreus; A. niger, A. quadrilineatus andS. brevicaulis; andA. terreus, A. niger andA. quadrilineatus.
