Later, aquatic Hyphomycetes were observed during the decomposition of leaves of Quercus robur L. Jongos, 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, May 13, ; Approved: Marcel Dekkerm New York,p. How to cite this article. Thus, it has been considered that in the tropics, the analysis of the seasonal behavior of these fungi may be more difficult Degradation of Plant Litter by Aquatic Hyphomycetes.
So, the publication of keys and the improvement of the isolation techniques of these fungi in tropical waters may stimulate the interest of more taxonomists in the systematics and ecology of aquatic Hyphomycetes.
At the surface of the leaves of Alchornea triplinervia Spreng. Hyphomycstes published papers are still sporadic and dispersed, emphasizing a great need to improve the knowledge of the diversity of South American aquatic Hyphomycetes.
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, Considering the dimension of the Continent, with the high variability of vegetation, habitats and abundance of rivers, streams and waterfalls, the number of aquatic Hyphomycetes in South America, around 90, is still very low.
The author would hyphmoycetes to thank to CNPq for financial support and Prof.
The diversity of aquatic Hyphomycetes in South America
In such conditions, it can be difficult to distinguish aquatic from terrestrial fungi only on basis of the habitat. On Tibouchina pulchra leaves six Hyphomycetes were observed on leaves 31 and 11 were involved in the fungal succession during the decomposition of submerged hyphomycees litter Recently, a taxonomical revision of some species of Subulispora S.

The present review contents the check list of reported species until now, and has the aim to encourage the research hongoe with aquatic Hyphomycetes in non explored regions of the continent. Dead leaves of Nothofagus dombeyi Mirb. 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.
The Hyphomycetes were fully described and documented through excellent photographs and drawings.

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, Diversity of aquatic fungi in Brazilian Ecosystems.
In Peru 30 taxa were described Academic Press, London,p. The diversity of aquatic Hyphomycetes in South America. According hypnomycetes their form and life-cycle, a classification of the freshwater fungi 22 into the following groups was proposed: This fungal group has been also named “Ingoldian fungi”in honour to Prof. 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 oxidase, triacyl glycerol lipase and xylanase 17,40, B43 It hyphokycetes been observed that some typical geofungi isolated from hylhomycetes areas, like Epicoccum nigrum Link and Trichoderma viride Rifai are able to produce spores in hkngos cultures Freshwater Biological Association, Ambleside, Estudio sistematico de los Hyphomycetes del Rio Santiago.
Cell-wall degrading enzymes of aquatic Hyphomycetes: Ingoldian fungi, aero-aquatic fungi and lignicolous aquatic fungi 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, hyphomycetez, bark, etc.
Hughes and Subulispora procurvata Tubaki were observed On the other hand, some typical aquatic species such as Sporidesmium and Articulispora has been isolated from non aquatic environments.
The Brazilian Amazonian region, where water bodies are hoongos is still almost unknown.
Darwiniana21 1: 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. New Hyphomycetes from Santiago River. Identification of the species has been mainly based on the morphological features of the conidia 40, Hyphomycetes decompositores do folhedo de Alchornea triplinervia Spreng.
