Average spore size?either less or more than 7 ? 6 ?m?splits the complex into a small-spored group of two (P. multiplex and P. atrolazulinus) and a large-spored group of three (P. mariae, P. marymargaretae, and P. purpureoniger). Basidiocarps of the small-spored species are somewhat smaller than the large-spored ones, are various shades of blue, dark all the way to black, with brownish tomentum only in early growth, have dark context, and pilei that tend to flare out at the edge. The large-spored species produce somewhat larger sporocarps, have light or lighter context than the pileipelis, usually retain some brown on the mature pileipellis, the edge of which tends to curl like a cabbage leaf. All will darken or blacken with age. The species of the P. multiplex complex are distributed in the boreal coniferous region, with the exception of Europe. One species (P. atrolazulinus) is known from three regions, eastern Asia (EA), northwestern North America (NWNA) and northeastern North America (NENA). Two species are known form two regions: P. purpureoniger in EA and NWNA, and P. multiplex in EA and NENA. Two species have been documented in one region only: P. mariae in NENA and P. marymargaretae in NWNA. A combination of location, macromorphology and spore size will usually differentiate the species of the complex.} }
