One unresolved question is soil reaction, once thought to be the answer in controlling this disease. Scientific studies an d practical experience over a long period had shown that acid soils having a pH of approximately 5.3 or below usually did not support common scab development, though sporadic and unexplained reports of disease occurrence in these soils were observed. In the late 1950s, however, such reports became more frequent in Maine and before the mid-1960s, losses relate d …

Forty-nine boletes have been collected and identified with their possible ectomycorrhizal associates for Maine. Most of the boletes are new reports for Maine. Acer negundo is a new host report for Boletinellus merulioides. Most of the ectomycorrhizal relationships reported here for Maine are confirmed by the work of others. Colored photos of thirty-seven Maine boletes are included.
