蓝蟹属生长在酸性介质（pH 2·0至0·3）中，用硫酸铜饱和（约100 μ l）。1 M），但对接近中性的低浓度铜（4 × 10− 5 M）敏感。其他11种真菌的不同之处在于，它们能耐受接近中性的相对高浓度的铜; 9种在pH 3.0到7.0之间耐受高浓度的铜，6种在pH 2.0到7.0之间耐受4 × 10− 3 M的硫酸铜。Oxine对Scytalidiumsp.的毒性较大。在中性下比在酸性pH下和在相对大量的铜存在下。EDTA对铜的毒性无明显影响。在中性和酸性pH下，该真菌对铁、钴和铬的氯化物具有相对耐受性。
Scytalidiumsp. grew in acidic media (pH 2·0 to 0·3) saturated with copper sulphate (approx. 1 M) but was sensitive to low concentrations of copper (4 × 10−5M) near neutrality. Eleven other fungi differed in that they tolerated relatively high concentrations of copper near neutrality; nine tolerated high concentrations from pH 3·0 to 7·0, and six tolerated 4 × 10−3M-copper sulphate at pH 2·0 to 7·0. Oxine was more toxic toScytalidiumsp. at neutrality than it was at an acid pH and in the presence of relatively large amounts of copper. EDTA had no appreciable effect on toxicity of copper. The fungus was relatively tolerant to chlorides of iron, cobalt and chromium at both neutral and acid pH.
