“…The leaves collected in 1990 were treated specially to detect the presence of aquatic Hyphomycetes sensu Ingold (Ingold, 1942(Ingold, , 1975 and aero-aquatic fungi sensu Van Beverwijk (Van Beverwijk, 1953). After rinsing with sterile water, leaf segments were cut from five leaves from each decomposition stage as described above.…”

~Ten species of fungi were isolated from floating leaves cut from plants of Nymphma alba in various initial stages of decay, which were collected from an acidic moorland pool. None of the fungal species isolated belonged to the aquatic Hyphomycetes sensu Ingold or the aero-aquatic fungi sensu Van Bevemijk. Growth experiments were conducted with five of the species on media containing glucose, polysaccharide or isolated cell walls of N. afba, each at three pH values. The fungi investigated were capable of growth on a variety of structural polysaccharides, indicating their potential importance in leaf degradation. Low pH inhibited growth on media containing glucose, pectin or cell wall fraction. Utilization of carboxymethylcellulose and crystalline cellulose did not differ much within the pH range studied. The fungi isolated were grown on N. afba leaf strips at three pH values to study the influence of pH on leaf maceration. All the fungi investigated could develop at low pH (4.0), but maceration was only observed at pH 5.5 or 7.5. It is likely that inhibition of pectin degradation is an important factor causing suppression of leaf fragmentation at low pH. This may contribute to the inhibition of the decomposition of macrophyte remains in acid aquatic systems.

“…2 later). The strains of the aquatic hypomycetes were identified on the basis of the morphology of asexual spores principally according to Ingold 14) and Carmichael et al 19) The representative genera included in the fungal collection were as follows (percentage frequency): Tetracladium (11.2%), Varicosporium (10.2%), Alatospora (10.0%), Clavariopsis (8.5%), Anguillospora (7.3%), Articulospora (7.3%), Tetrachaetum (6.8%), Tricladium (4.9%), Tripospermum (4.6%), Volucrispora (3.9%), Lemonniera (3.4%), Flabellospora (2.7%), Triscelophorus (1.5%), and Dendrosporomyces (1.2%).…”

“…Aquatic hyphomycetes are a phylogenetically diverse group of mitosporic fungi with peculiarly shaped spores which are specifically adapted to an aquatic environment. 14) As a typical habitat, they grow on submerged dead leaves and wood, and are deeply involved in the decomposition of plant-derived materials in a freshwater ecosystem. They might be novel sources of natural bioactive products because their components have not been investigated in detail due to difficulties in isolation and cultivation.…”

“…They were ubiquitous in this extreme environment and parasitic and saprophytic in their characteristics. Ingold (1942Ingold ( , 1976, Padgett (1976), and Willoughby and Archer (1973) suggested that they possess certain characteristics that allow them to favourably compete with other microorganisms in aquatic habitats (Suberkropp and Klug, 1981).…”

Litter production and its decomposition is a major source of nutrients for mangrove ecosystems. This study was conducted on a naturally growing mangrove population in the Sandspit area in Karachi, Pakistan, during 2007 and 2008. Avicennia marina (Forssk.) Vierh. forms an almost pure population in Sandspit mangrove swamps. To examine the details of temporal fluctuation in litter accumulation and its decomposition, observations were taken at monthly intervals. Results showed that the maximum litter accumulation occurred during the monsoon and post-monsoon season with the maximum accumulation in August (68.76 ± 8.72 g/ m 2 ), while minimum litter accretion occurred in January (13.61 ± 1.46 g/m 2 ). The decomposition rate was highest (47.7%) in June and almost completed in 8 months. The exponential curve model showed highly significant differences between the rates of decomposition in various months both at ground level and at a 5-cm depth below the surface. Soil fungi and major bacterial groups were examined as decomposers. Aspergillus Micheli was the most diverse group of the soil-borne microflora in the mangrove habitat. The fungal spore load in the soil was greater in summer and lower in winter.
