Darwiniana21 1: In the same Reserve, Dendrosporomyces splendens Nawawi Nawawi, a typical species from water, was isolated from Alchornea triplinervia and Euterpe edulis Mart. Acta Botanica Brasilica5 1: The authors observed 14 taxa of Ingoldian fungi, identified nine at specific level and documented their taxonomic features by spore drawings. Also the quality of the taxonomical descriptions and drawings must be improved.
The diversity of aquatic Hyphomycetes in South America
Hifomicetes Deuteromycotina acuaticos de Tierra del Fuego. Biodiversity of Tropical Microfungi. 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.
Cell-wall degrading enzymes of aquatic Uyphomycetes The taxonomical descriptions are complete and well documented by drawings. As the aquatic Hyphomycetes has been characterized as one of the most active fungi in the mineralization of leaf litter, and consequently important dynamizers of the nutrient cycling in the aquatic environments, it has been considered relevant to increase the knowledge of the species diversity in terms of geographic distribution.
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 The Hyphomycetes were fully described and documented through excellent photographs and drawings. Matsushima Mycological Memoirs no. Thus, it has been considered that in the tropics, the analysis of the seasonal behavior of these fungi may be more difficult Hifomicetos decompositores do folhedo de Euterpe edulis Mart.
Aquatic fungi in leaves submerged in a stream in the Atlantic Rainforest. Matsushima 41,42 greatly contributed to the knowledge of Hyphomycetes in South America.
Fungal succession on leaves of Alchornea triplinervia Spreng. 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, Hoehnea29 1: 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.

Academic Press, London,p. Hong Kong University Press, p. Degradation of Plant Litter by Aquatic Hyphomycetes. 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.
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, Hyphomycetes from leaf litter of Miconia cabussu in the Brazilian Atlantic Rain forest.
It has been observed that some typical geofungi isolated from such areas, like Epicoccum nigrum Link and Trichoderma viride Rifai are able to produce spores in submerged cultures The published papers are still sporadic and dispersed, emphasizing a great need to improve the knowledge of the diversity of South American aquatic Hyphomycetes. Marcel Dekkerm New York,p. Initial colonization, nutrient supply, and fungal activity on leaves decaying in hyphomhcetes.
Several decaying palmae petioles mainly but also leaf litter, fruits and soil samples were collected in the nyphomycetes of some rivers in the equatorial Amazon region of Ecuador and Peru. More recently 9 taxa were isolated from decomposing leaves of Miconia cabussu Kirk was reported Fact is that, hognos 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 ecology of aquatic Hyphomycetes. The Brazilian Amazonian region, where water bodies are plenty is still almost hyphomyctees. In Venezuela Table 1 11 taxa of aquatic Hyphomycetes were isolated from submerged leaf litter, branches and petioles of Casuarina in streams, pools and waterfalls in the surroundings of Caracas B43 Acta Botanica Brasilica, 11 2: In Chile Table 1samples of wood, leaf litter and insects were collected in several streams and lakes in hyphomyceyes temperate region of Osorno Only 1 record, Helicosporium sp.
Some aquatic fungi are able to degrade animal parts like insect exoskeletons, hair and fish scales Dead leaves of Nothofagus dombeyi Mirb. The hydrodynamic shapes of the conidia confers to these fungi higher ability to remain suspended in the water for extended periods of time and improve the chances of the propagules to become attached to organic substrates, available for colonization.
