The quantification of the taxa in revisions concerned with fungal diversity in the tropics may result different numbers in function of several definitions of aquatic fungi and also depends on the availability of the literature.

Some aquatic fungi are able to degrade animal parts like insect exoskeletons, hyphomycetez and fish scales How to cite this article.

The aim of this revision is to present the state of the art of the studies concerned with aquatic Hyphomycetes in Brazil, in the context of South America, to encourage the conduction of surveys in unexplored areas of the continent.

Academic Press, London,p. Ingold, who was one of the most important pioneers in the study of aquatic Hyphomycetes In Peru 30 taxa were described Hyphomycetes decompositores do folhedo de Alchornea triplinervia Spreng. New Hyphomycetes from Santiago River.

Many fungi with star-like conidia or considered aquatic were isolated but it is not clear if they were obtained from really submerged substrates. Research on aquatic Hyphomycetes: Thus, it has been considered that in the tropics, the analysis of the seasonal behavior of these fungi may be more difficult hyphomycwtes Influence of nutrients concentration on the aquatic mycota of leaves submerged in a stream in the Atlantic rainforest.

However, the scarcity of taxonomical keys with tropical species and the difficulty of obtaining cultures on agar media has disencouraged further initiatives. Besides, several other studies were performed at several localities in Argentina, involving the sampling of leaf litter or woody debris, from which many not typical aquatic fungi were isolated 3,4,11,12, Ingoldian Hyphomycetes fungi that present conidia with hydrodynamic shape and are exclusively dependent on aquatic environment for reproduction ; aero-aquatic Hyphomycetes fungi that may support submerged conditions but reproduce out of aquatic environmentsand terrestrial-aquatic Hyphomycetes and submerged-aquatic Hyphomycetes, which are observed in aquatic and terrestrial environments as facultative organisms.

Hoehnea29 1: Cell-wall degrading enzymes of aquatic Hyphomycetes: Hughes and Subulispora procurvata Tubaki were observed In Brazil, as well as probably in other countries of South America, the interest of researchers and students in the taxonomy of aquatic Hyphomycetes has come from the observation of the species in ecological studies about leaf litter decomposition and fungal succession.

The diversity of aquatic Hyphomycetes in South America

Diversity of aquatic fungi in Brazilian Ecosystems. In the same region, the mycota associated with leaves of Ficus microcarpaAlchornea triplinervia and Quercus robur were compared, evaluating the diversity 53the methods for fungal quantification to express the colonization intensity 45 and the correlation between fungal diversity zoosporic fungi and aquatic Hyphomycetes and macro and microelements during the decomposition 54, Acta Botanica Brasilica, 11 2: On Tibouchina pulchra leaves six Hyphomycetes were observed on leaves 31 and 11 were involved in the fungal succession during the decomposition of submerged leaf litter The Brazilian Amazonian region, where water bodies are plenty is still almost unknown.

In such conditions, it can be difficult to distinguish aquatic from terrestrial fungi only on basis of the habitat.

Fact is that, besides of the polemic discussion about which fungi are truly aquatic and if the terrestrial fungi may keep their saprophytic hability even in submerged conditions, the recognition of the importance of the aquatic Hyphomycetes has been continuously increased since many years. Identification of the species has been mainly based on the morphological features of the conidia 40, In the tropics the richness of these fungi is probably influenced by the type of substrates, chemical and physical changes in the streams 35 as well as due complex interactions among several climatic and limnological factors 9, The conidia may be trapped in foam, dispersed in the water, floating on the water surface or are associated to organic decomposing substrates as leaf litter and twigs Their habitats are preferencially streams with clear, clean, well-aerated waters, with moderate turbulence, and also reservoirs and lakes with different kinds or levels of pollution.

Only 1 record, Helicosporium sp. At hyphomucetes surface of the leaves of Alchornea triplinervia Spreng. Based on accumulative results of several worldwide studies, about anamorphic genera and species of aquatic Hyphomycetes are known until now Aquatic Hyphomycetes, also named Ingoldian or freshwater fungi, constitute a group of anamorphic fungi that are typically aquatic, producing tetraradiate, sigmoid or spherical conidia hingos submerged plant debris leaf litter, petioles, bark, etc.

Estudio sistematico de los Hyphomycetes del Rio Santiago. During the autumn in temperate climates, streams receive a great supply of tree leaves which may be densily colonize by a high diversity of aquatic Hyphomycetes 9.

The eminent Professor studied these fungi in several aquatic environments in the United Kingdom and other countries starting from 40’s, describing species that are now considered cosmopolitan 36, Handbook of Applied Mycology: These fungi are considered predominant in the leaf decomposition process in aquatic environments. Marcel Dekkerm New York,p. Freshwater Biological Association, Ambleside, Since in many countries no data about this fungal group have been published, and the studies are very scarce, sporadic and dispersed, it is difficult to draw conclusions about the geographic distribution of aquatic Hyphomycetes in South America.
