Although the number of taxa and studies are higher in Brazil than in other South American countries, no new species have been described until now.

Springer-Verlag, Berlin,p. Initial colonization, nutrient supply, and fungal activity on hongks decaying in streams. At the surface of the leaves of Alchornea triplinervia Spreng. 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.

More recently 9 taxa were isolated from decomposing leaves of Miconia cabussu Surveys were performed in the subtropical region of Santiago River in Buenos Aires 5,6,7resulting in the description of 19 Hyphomycetes including nine new species and one new combination, Dictyochaeta assamica Agnihothrudu Arambarri, Cabello and Mengascini.

Hongos saprobios en Chile: However, among the aquatic Hyphomycetes there are species that produces sigmoid, fusiform, coiled and spherical conidia too, which are also dependent of the aquatic environment to complete their life cycle 22, In Argentina the sampling of submerged mixed leaf litter, leaves of definied species such as Salix sp. Beltrania, Camposporium, Chaetendophragmia, Cladosporium, Cryptophiale, Dactylella, Dictyochaeta, Kionochaeta, Phaeoisaria, Subulispora, Tetraploa and other well-known terrestrial genera of Hyphomycetes are usually found on submerged litter as “facultative aquatic fungi” Some aquatic fungi are able to degrade animal parts like insect exoskeletons, hair and fish scales Acta Botanica Brasilica5 1: There is an evidence that aquatic Hyphomycetes are able to degrade several plant cell polymers such as cellulose, hemicellulose, pectin 16 and probably lignin 35,40producing amylase, cellulase, pectinase, protease, pyrocatechol honogs, triacyl glycerol lipase and xylanase 17,40, Thus, some species were observed during fungal decomposition of leaves of Ficus hognos L.

Later, aquatic Hyphomycetes were observed during the decomposition of leaves of Quercus robur L. 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.

The conidia may be trapped in foam, dispersed hyphomyctes the water, floating on the water surface or are associated to organic decomposing substrates as leaf litter and twigs 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, Biodiversity of freshwater fungi.

CAB International,p. From the taxonomical point of view, the aquatic Hyphomycetes constitute an artificial phylogenetically heterogenous group, being anamorphs of Ascomycota and Basidiomycota 1, Production of extra-cellular cellulase by Lunulospora curvula and Flagellospora penicillioides. The authors observed 14 taxa of Ingoldian fungi, identified nine at specific level and documented their taxonomic features by spore drawings.

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. Also the quality of the taxonomical descriptions and drawings must be improved.

The diversity of aquatic Hyphomycetes in South America

Hyphomycetes on Alchornea triplinervia Spreng. However, the scarcity of taxonomical keys with tropical species and the difficulty of obtaining cultures on agar media has disencouraged further initiatives. Furthering the studies with Hyphomycetes from Santiago River, Cabello et al. Freshwater Biological Association, Ambleside, The author would like to thank to CNPq for financial support and Prof.

Estudio sistematico de los Hyphomycetes del Rio Santiago prov. This fungal group has been also named “Ingoldian fungi”in honour to Prof. Thus, it has been considered that in the tropics, the analysis of the seasonal behavior of these fungi may be hypgomycetes difficult Minimidochium parvuma new species of hyphomycete from Argentina. Hyphomycetes from leaf litter of Miconia cabussu in the Brazilian Atlantic Rain forest.

Research on aquatic Hyphomycetes: Kirk was reported In Peru 30 taxa were described Ingoldian fungi, aero-aquatic fungi and lignicolous aquatic fungi In Chile Table 1samples of wood, leaf litter and insects were collected in several streams and lakes in the temperate region of Osorno
