Aquatic hyphomycetes were discovered 50 years ago by C.T. Ingold. They remained a relatively obscure group until their role as intermediaries between deciduous leaves and stream invertebrates was established some 20 years ago. This book provides a summary and critical evaluation of the biology and ecology of these organisms. A special effort was made to evaluate the potential and actual insight that had been or will be derived from work in related disciplines such as the ecology of other fungal… 

An Illustrated Key to the Common Temperate Species of Aquatic Hyphomycetes

This chapter presents a key for the identification of the common species of aquatic hyphomycetes found in streams in temperate climates based mostly on the morphology of detached spores (conidia) obtained by inducing fungal sporulation on plant litter in the laboratory.

Out of the rivers: are some aquatic hyphomycetes plant endophytes?

Unexpectedly, several lines of evidence now suggest that some Ingoldian fungi are also plant endophytes, that is, they grow in plants without producing symptoms.

Molecular approaches applied to aquatic hyphomycetes

Aquatic Hyphomycetes in Alpine Streams

In the mid-twentieth century Ingold (1942) discovered a diverse community of stream fungi that he called aquatic hyphomycetes, which can be broadly delimited by their thin-walled and hyaline (nonpigmented) conidia with characteristic shapes and their association with submerged decaying leaves and wood in streams.

Effect of temperature on growth and survival of five aquatic hyphomycetes

Study of Aquatic Fungi and Their Role in Putrefaction of Allochthonous Leaves at Hanna Lake (Balochistan)

The micro fungal flora of the mud and water of Hanna Lake in Quetta district was investigated during 2015, using Baiting techniques and it was shown that phylloplane population declined quite rapidly.

Aquatic hyphomycetes in Catamaran Brook: colonization dynamics, seasonal patterns, and logging effects

Aquatic fungal colonization dynamics and seasonal patterns were investigated in two sites in Catamaran Brook, New Brunswick, Canada, as part of a larger study to evaluate logging effects on a salmon stream, and contrary to expectation neither mesh size nor preliminary logging activity had a consistent effect on community structure.

Aquatic Hyphomycete Species Are Screened by the Hyporheic Zone of Woodland Streams

Results of this study highlight that the hyporheic zone exerts two types of selection pressure on the aquatic hyphomycete community, a physiological stress and a physical screening of the benthic spore pool, both leading to drastic changes in the structure of fungal community.

Landscape scale ecology of Tetracladium spp. fungal root endophytes

Background The genus Tetracladium De Wild. (Ascomycota) has been traditionally regarded as a group of Ingoldian fungi or aquatic hyphomycetes—a polyphyletic group of phylogenetically diverse fungi



Aquatic hyphomycetes of decaying alder leaves


No major differences in aquatic hyphomycete community structure occurred between oak and maple leaves and although a large number of the same species occurred in data from all three techniques, species rankings were dissimilar.

The nutrition and physiology of some aquatic Hyphomycetes were examined and several species utilized almost all the carbohydrates tested and most gave a molar growth yield between 80 and 95 mg.

Effects of Cadmium on Aquatic Hyphomycetes

Calcium content seems to be the most important factor responsible for the different sensitivity of aquatic hyphomycetes in hard and soft water.

The maceration of deciduous leaf litter by aquatic hyphomycetes

Fine particulate release coincided with increases in fungal biomass (ATP) and activity of enzymes in the supernatant which degraded carboxymethylcellulose, xylan, and polygalacturonic acid, suggesting involvement of pectin trans-eliminase in the softening of leaf tissue by this fungus.

Seasonal occurrence of Conidia of Aquatic Hyphomycetes (Fungi) in Lees Creek, Australian Capital Territory

Analysis of variance showed significant differences between the two sites for concentrations of conidia of individual species and of total conidia, which correspond with differences in seasonality of litter fall in the Northern Hemisphere compared with Australia.


Two interesting Hyphomycetes isolated from horse dung from Mussoorie, Uttar Pradesh, India, are described and placed in the family Torulaceae Corda emend.
