Degradation of Plant Litter by Aquatic Hyphomycetes.

Hifomicetes Deuteromycotina acuaticos de Tierra del Fuego. Minimidochium parvuma new species of hyphomycete from Argentina. Aquatic fungi in leaves submerged in a stream in the Atlantic Rainforest.

Later, aquatic Hyphomycetes were observed during the decomposition of leaves of Quercus robur L. One year later three groups were better distinguished among hongoa former: The hydrodynamic shapes of the conidia confers to these fungi higher ability to remain suspended in the water hphomycetes extended periods of time and improve the chances of the propagules to become attached to organic substrates, available for colonization.

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

Influence of nutrients concentration on the aquatic mycota of leaves submerged in a stream in the Atlantic rainforest. 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, There may be many interesting additional data in regional journals, monographs, thesis and reports.

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 Many fungi with star-like conidia or considered aquatic were isolated but it is not clear if they were obtained from really submerged substrates.

More effort is needed in terms of surveys and taxonomical studies to improve the knowledge of these fungi. Identification of the species has been mainly based on the morphological features of the conidia 40, The group of the aquatic Hyphomycetes comprises fungi that produce conidia exclusively in the aquatic environment or in the interstitial water among soil particles. Buenos Aires Province, Argentina.

The diversity of aquatic Hyphomycetes in South America

The ecology of aquatic Hyphomycetes. 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.

Handbook of Applied Mycology: 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.

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. Ingold, who was one of the most important pioneers in the study of aquatic Hyphomycetes 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, Tropical Mycology, Science Hyphomyetes, Inc.

Sutton were observed during the decomposition of leaves of Cedrela fissilis Vell. In the present revision representants of all these group were considered. Hifomicetos decompositores do folhedo de Euterpe edulis Mart. Academic Press, London,hojgos.

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 diversity of aquatic Hyphomycetes in South America. Hyphomycetes from leaf litter of Miconia cabussu in the Brazilian Atlantic Rain forest. Micoflora de la hojarasca de Nothofagus dombeyi.

In Chile Table 1samples of wood, leaf litter and insects were collected in several streams and lakes in the temperate region of Osorno 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, Services on Demand Journal.

In the revision for tropical freshwater Hyphomycetes Goh 21 listed 19 taxa to South America without specifying the countries. In the same Reserve, Dendrosporomyces splendens Nawawi Nawawi, a typical species from water, was isolated from Alchornea triplinervia and Euterpe edulis Mart. Comparing the results among the countries, one may observe that some species such as Anguillospora longissima Sacc.
