Aquatic hyphomycetes colonizing the submerged chirpine (pinus roxburghii SARG .) needle litter in a high altitude, Kumaun Himalayan stream were studied. 15 species belonging to different genera of aquatic Hyphomycetes have been recognized as the colonizers of chirpine needle litter. Clavariopsis aquatica, Heliscus lugdunensis, Lunulospora cymbiformis, Triscelophorus acuminatus and T. monosporus were found with a high frequency of occurrence. The conidial production was highest in Flagellospora penicillioides, however, Campylospora chaetocladia, L. cymbiformis and T. acuminatus had less number of conidia per unit area of pine needles. The chirpine needle litter decomposition in the freshwater habitat is also discussed. 相似文献

Aquatic hyphomycetes (Moniliales) constitute a predominant mycoflora on submerged decaying allochthonous plant debris, both
in lentic and lotic systems. These fungi exhibit a remarkable seasonality, and to explain this, a couple of models have been
put forward, which tend to establish a strong correlation of their seasonal occurrence with temperature and pH of the aquatic
systems. This study provides additional evidence that both vegetative and reproductive success of aquatic hyphomycetes is
significantly affected by the interspecies interactions within this group. 相似文献

Significantly more species of freshwater hyphomycetes colonized bait leaves of alder (16 species) and willow (14 species)
during early submersion period (1 wk) than those of oak (8 species). Production of conidia was also higher on alder and willow
leaves than on oak leaves. Higher amounts of dry mass were lost from the alder (28.6%) and willow leaves (29.4%) than from
the oak leaves (18.7%). Rapid loss of dry mass was accompanied by rapid development of a fungal community. Fungal species
took a longer time (6 wk) to reach their peak of occurrence on oak than on willow and alder leaves (3–4 wk).Flagellospora curvula dominated the assemblages of freshwater hyphomycetes on alder and willow leaves, andLunulospora curvula dominated the assemblage on oak leaves. The freshwater hyphomycete community showed higher values of species diversity (H
value) on oak leaves than on alder and willow leaves. 相似文献

Cryptophiale sphaerospora sp. nov. is described and illustrated based on a single collection attached to a synnematous fungus,Janetia synnematosa, from a dead bamboo culm. It differs from other species ofCryptophiala in having spherical to subspherical conidia and a cerebroid layer of phialides. The overall morohology of this species is
smaller than that of previously described species. 相似文献
