“…Cadmium appears to be accumulated to quite high values in macrofungi, averaging around 5 /ig g"^ d.wt though concentrations of up to 40//gg"' d.wt have been recorded (Byrne, Ravnik & Kosta, 1976). Average concentrations of As, Cu, Hg, Mn, Se and Zn in a range of up to 27 species were 1, 50, 2, 3, 30, 1-5 and 114//g g"^ d.wt respectively (Byrne et aL, 1976). However, a wide range of accumulation values can occur depending on the species and location of 46 G. M. Gadd growth; caps of Laccaria amethystina exhibited total As concentrations of 100-200/ig g~^ d.wt (Stijve, Vellinga & Hermann, 1990;Byrne et al, 1991).…”

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.

“…Stijve ( 1977) found the average selenium concentration in nine samples of Boletus edulis to be 13 mg kg-1 . Byrne et al (1976) reported the average concentration of arsenic in 27 species of mushrooms as 1.3 mg kg-1. High concentrations of arsenic were found in Lycoperdon perlatum (6.8 mg kg-1 , Byrne et al, 1976), in the edible Laccaria amethystea (up to 182 mg kg-1, Byrne eta!., 1983, Stiyve eta/., 1990, in Laccaria laccata (average of 10 samples 10.9 mg kg-1), in Laccaria fratema (average off our samples 129 mg kg-1, Stijve et al, 1990), in Agaricus haemorrhoidarius (1.1-7.3 mg kg-1 ), in Agaricus.…”

Graphite furnace atomic absorption spectrometry (standard addition method) was used to determine the total arsenic in wild-growing mushrooms after digestion with nitric acid, then with perchloric acid and in associated soils after digestion with mixtures of nitric and hydrofluoric acids in a microwave system. Among 83 species of mushrooms the highest concentrations of arsenic on a dry mass basis were found in Laccaria amethystea (26-125 mg kg-1 ), Laccaria laccata (11-33 mg kg-1 ), Thelephora terrestris (38 mg kg-1 ), Boletus cavipes (11.6 mg kg-1 ) and Ramaria botrytis (10 mg kg-1). Mushroom caps of L.laccata, L. amethystea, and B. cavipes had approximately double the arsenic concentrations found in stems. The arsenic concentrations in caps of L. amethystea and L. laccata were directly proportional to the concentrations in the soils. The concentrations of arsenic in the soils were in the range 6.5-65 mg kg-1. Among the 19 mushroom caps with arsenic concentrations above the method detection limit of 0.2 mg As/kg dry mass, only L. amethystea and L. laccata had arsenic concentration ratios 'cap/soil' higher than 1 {between 1.1 and 1.9). Thelephora terrestris had a ratio of 2.37.

“…As mentioned above, it was recognised already in the 1960's and early 1970's that some species of mushrooms are more efficient to take up radionuclides from the environment than other species (Moser, 1972;Grüter, 1967;Rohleder, 1967a;Johnson and Nayfield, 1970;Witkamp, 1968), and this observation has been confirmed by many investigators after the Chernobyl accident. The finding was not totally unexpected as some mushroom species are well known to accumulate specific minerals and heavy metals (in the natural stable form) in their fruit bodies (Byrne et al, 1976;Bowen, 1979;Kalać and Svoboda, 2000).…”
