The usually diversified and competitive mycota present in the leaf tissues, before submergence, may include “autochthonous” fungi, that resist to drastic environmental changes and participate on further decomposition processes, until some of the native aquatic fungi are able to colonize and dominate the substrate Park Non-crystals in axial parenchyma cells. The presence of triplinervla zoosporic fungi in the decomposing leaves, resulted tripilnervia an increase of the total number of registers, from 16 in December of to 38 in January ofduring the first period of the experiment table 1.

Atlantic forestintraspecific variationtropical tree. A principal component analysis was used to order the populations as well as to find the higher variance component. Rays more than 10 per mm abundant. This is the first paper about the fungal succession on the decomposition of leaves submerged in a lotic ecosystem alchorneaa Brazil. Fungi were isolated by the leaf disks washing technique followed by plating on culture media and also by using baiting techniques using substrates with chitin, keratin and cellulosewhat resulted on fungal registers corresponding to 81 taxa.

The fungal succession table 1 may not be well defined by the sequential occurrence of taxonomic groups such as was stated in the studies of Newell and Trippinerviabut some tendencies may be pointed out from alchornae results.

During the first period of the experiment, the highest number of fungal specimens was registered in January of 38 registers and the lowest in August of 13 registers. A total of 81 taxa distributed in registers were obtained table 1representing respectively: Texture Texture is reported to be medium to coarse. However, the fungi present at the beginning of the succession showed higher register numbers than those at the end of the process table 1.

Among them, the following species presented the highest numbers: Although the aquatic Hyphomycetes, as well as some zoosporic fungi may be considered initial decomposers, with high capacity to degrade cellulose and lignin compounds Willoughbytheir presence in the leaves triplinervoa A. Light accounted for the variations found in palisade and spongy parenchyma while the combination of light and soil water determined the variations found regarding the outer epidermal cell wall of the abaxial surface, the percentage of sclerenchymatous area in relation to the total midrib area and the compaction of the spongy parenchyma.

The most triplinerviw species found during this study of the fungal succession were Trichoderma viride Pers. From the eighth and ninth months on, Catenophlyctis variabilis trriplinervia, Fusarium lateritium, Mucor hiemalis f.
