“…Mercury-tolerant fungi have been isolated from the surfaces of seeds treated with mercury compounds. These include Pyrenophora avenae, Penicillium crustosum, Cladosporium cladosporoides, Syncephalastrum racemosum and Ulocladium atrum (Ross & Old, 1973;Greenaway, Cripps & Ward, 1974).…”

SUMMARY This review details the major interactions of fungi with toxic metal species. Physico‐chemical and biological aspects are discussed including definitions and classification of metals in biological contexts, mechanisms of metal fungitoxicity, resistance and tolerance, environmental influences and the occurrence of fungi in metal‐polluted habitats. Cellular interactions include extracellular precipitation and complexation, binding to cell walls, transport of monovalent and divalent metal cations, intracellular fates of toxic metal species (including metal‐binding proteins and peptides, and vacuolar compartmentation), and metal transformations including organometal(loid) synthesis. Significant interactions between metals and mycorrhizal fungi and macrofungi are summarized with reference to the amelioration of plant phytotoxicity and metal accumulation respectively. Biotechnological aspects of metal‐fungal interactions relate to the biological treatment of metal‐contaminated effluents and waste streams for metal removal/recovery and environmental protection.

“…Development of resistance to organomercurial fungicides in vivo has been demonstrated in a number of fungal genera including Aspergillus (Gibson, 1953), Chrysosporium (Williams & Pugh, 1975), Leptosphaeria (Harrower, 1976), Pyrenophora (Noble et al, 1966), Cladosporium, Syncephalastrum (Greenaway, 1972a), Ulocladium (Greenaway, 1973 b) and Penicillium (Kiessling, 1961 ;Greenaway, Cripps & Ward, 1974).…”

A spectrophotometric technique is described by which uptake of 2-chloromercuri-4-nitrophenol (CMNP), an organomercurial compound toxic to fungi, may be continuously monitored for 30 min periods. The method is demonstrated using mercury-resistant and mercury-susceptible isolates of Penicillium expansum and Cladosporium cladosporioides. With P. expansum no consistent differences in uptake were recorded. Mercury-resistant isolates of C. cZadosporioides consistently absorbed less CMNP into their hyphae than did mercury-susceptible isolates.
