Hyphomycetes decompositores do folhedo de Alchornea triplinervia Spreng. Services on Demand Journal. 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. Hyphomycetes decompositores do folhedo de Tibouchina pulchra Cogn.
Comparing the results among the countries, one may observe that some species such as Anguillospora longissima Sacc. Almost all studies are taxonomical, some with proper drawings and complete descriptions, but no keys have been provided yet, nor there is a specific culture collection for preserved strains.
Diversity of aquatic fungi in Brazilian Ecosystems.
The diversity of aquatic Hyphomycetes in South America
The present review contents the check list of reported species until now, and has the aim to encourage the research concerned with aquatic Hyphomycetes in non explored regions of the continent.
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 Hhphomycetes America.
Biodiversity of Tropical Microfungi. Acta Botanica Brasilica, 11 2: Springer Verlag, Berlin,p. Recently, a taxonomical revision of some species of Subulispora S. The group of the aquatic Hyphomycetes comprises fungi that produce conidia exclusively in the aquatic environment or in the interstitial water among soil particles. Fungal succession on leaves of Alchornea triplinervia Spreng.
Ingoldian fungi, aero-aquatic fungi and lignicolous aquatic fungi Production of extra-cellular cellulase by Lunulospora curvula and Flagellospora penicillioides. These fungi are considered predominant in the leaf decomposition process in aquatic environments.
The taxonomical descriptions are complete and well documented by drawings. May 13, ; Approved: Hyphomycetes from leaf litter of Miconia cabussu in the Brazilian Hyphomycets Rain forest.

Besides, several other studies were performed at several localities in Argentina, byphomycetes the sampling of hyphomycetew litter or woody debris, from which many not typical aquatic fungi were isolated 3,4,11,12, The term “tetraradiate fungi”has been also honvos used to name this fungal group because many species produce conidia with a hoongos or star-like shape, build by hyphlmycetes central part, from which three or four arms are projected in divergent positions 18, Aquatic Hyphomycetes, also named Ingoldian or freshwater fungi, constitute a group of anamorphic fungi that are typically aquatic, producing tetraradiate, sigmoid or spherical conidia on submerged plant debris leaf litter, petioles, bark, etc.
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. 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 Micoflora de la hojarasca de Nothofagus pumilio. Micoflora de la hojarasca de Nothofagus dombeyi. Dead leaves of Nothofagus dombeyi Mirb. 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.
Mainly occurring in lotic systems, these fungi are considered to be one of the most active groups of organisms in the decomposition of leaf litter, and play a crucial role in the trophic chain.
CAB International,p. 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,
