Abstract:
Mycologistas had two centuries, seeking to identify the diversity of fungal organisms, andresearch on the phylogeny greatchallehg. In the past decade, DNA sequencing has providednew characters for phylogeny analysis off ungi, allowing the identification of ten (10) phylum, kingdom fungi monophyletic members. A new phylogenetic tree has suggest that the largest number of species in some groups may be d uto factors such as the difficult of isolaating fungi and application of inabilit to molecular methods, but there is no doubt that the Ascomycota phylum (64,162 spécies) and Basidiomycota (31,515), comprise the largest fungal diversity. According to this new proposal phylogenetic zoosporic fungi and zigosporic were not reportd as monophyletic and significant changes are groups traditionally inclued (Chytriomycota and Zigomycota). Currelent they are described and cataloged nearly 100,000 spécies off fungi. However it is estimated that there are 1.5 million species. In Brazil, on indiscriminate few mega-diversity data is cataloged and published however there is high efforts of researchers and instituions interested in promoting the the inventory of fungal biodiversity inthe country. It is known that the fungal biodversit is cosmopolitan nature. Thus, it can be presents in many diferent envirinments, including water reservoirs, , open systems to the elements of nature that are conducive to biodversity of filmentous fungi, groups that stand out due to its wide distribution and adaptation. Due to the importance of these microorganisms to the environment and to humanity, it is essential to study the filamentous fungal species. It is inferred, therefore, that the water reservoir “Engenheiro Ávidos” in Cajazeiras Paraíba chosenfor this study consisted of importante fungi insulating suppot. The suvey, from sampling of water samples that were processed in Microbiology Labortory CFP/ UFCG, and seeded in Medium+chloramphenicol (2.5%) resulted in growth of 23 colonies, and can identtify 11 fungi Genres, 11(eleven) of the phylum Ascomycota and six (6) colonies were not possible to identify. New abd ongoing studies should be implemente and stimulated by research institutions governmet agency and notified to the community directly involver wit the consumption of water on the potencial risks of contamination and heanth.
