  1. An interfertile pairing is designated by a plus symbol and a non-interfertile pairing by a negative symbol; symbols in brackets indicate results that are less definite (the interpretation for the pairings represented by each symbol being less clear). All pairings replicated once, mostly successfully, but occasional failures of both replicates denoted by gaps (one or both isolates in each replicate did not grow or became contaminated). At least one positive replicate, and usually both, confirmed interfertility. For Armillaria sp. nov., identification is based on ITS sequencing (see Table 2)
