The live and dead tissues, and trapped leaf litter by the epiphytic tree fern Drynaria quercifolia associated with riparian tree species of Konaje (west coast) and Sampaje (Western Ghat) streams of India during dry (summer) and wet (monsoon) seasons yielded 37 species of water-borne conidial fungi on bubble chamber incubation. Dead bracket leaves of fern possess the highest species as well as conidia in Konaje, while the trapped leaf litter in Sampaje. During summer, the diversity was highest in bracket leaves in both locations, while in monsoon season it was highest in rhizomes of Konaje and in trapped leaf litter in Sampaje. Even though the conidial output from tissues of Drynaria and trapped leaf litter were not equivalent to stream submerged leaf litter, the species richness ranged between 40% and 75% in Konaje and Sampaje streams. As stable epiphyte, Drynaria exposed to wet and dry regimes in tree canopies of west coast and Western Ghats likely to serve as host for perfect states of water-borne hyphomycetes.

Zoosporic and conidial fungi species and environmental factors in 12 various sites of the River Biebrza in Biebrza National Park were studied. Samples of water were collected in autumn 1999 and spring 2000 for hydrochemical analysis in order to determine the number of fungal species. Buckwheat-seeds, hemp- seeds, cellophane and snake exuviae were used as bait during exposure in a laboratory. 199 lower aquatic fungus species were found in various sites of the River Biebrza. 16 species were recorded for the first time from Poland.

Ochratoxin A (OTA) is a mycotoxin frequently found in human blood and milk samples in the colder climatic zones. In addition to dietary intake, exposure may occur by inhalation of toxin containing fungal conidia. The purpose of this work was to investigate the level of OTA in blood samples from farm workers and non-farm working controls, and to examine if serum levels of OTA were related to inhalatory exposure to conidia of Penicillium verrucosum, the main OTA producer in temperate climates. Blood samples from 210 participants were analysed for the presence of OTA and IgG antibodies against P. verrucosum conidia. The concentration of OTA was determined by HPLC (DL 10 ng/l), and the IgG level was determined by ELISA. All serum samples contained OTA (mean 397 ng/l, range 21-5534 ng/l). The OTA level in serum was unrelated to farm working, gender, age, and IgG level. The mean IgG level was significantly higher among farm workers than controls. Farm working, or increased inhalatory exposure to P. verrucosum, was not related to higher OTA serum levels. Inhalatory exposure to OTA from farm working seems to be of minor importance compared to dietary intake.
