Phaeolus schweinitzii, commonly known as velvet-top fungus, dyer's polypore, dyer's mazegill, or pine dye polypore, is a
The fruiting bodies, appearing in late summer or fall, commonly incorporate blades of grass, twigs, or fallen pine needles as they grow.
The effect, impact and significance of infection by this fungus is rooted in the fact that it causes brown rot, which degrades the cellulose. Thus there is a loss of tensile strength which often leads to brittle fracture near the stem base, even at a fairly early stage of decay. Decay initiated above ground can lead to branch snap or breakout.[5]
P. schweinitzii is native to North America and Eurasia,[1] and has been identified as an exotic species in New Zealand, Australia, and South Africa.[6] It is not edible.[7]
As its common name suggests, the dyer's polypore is an excellent natural source of green, yellow, gold, or brown dye, depending on the material dyed and the mordant used.[3][8]
P. schweinitzii is named after Lewis David de Schweinitz, a Pennsylvania-born Moravian minister and important early American mycologist.
Similar species include Heterobasidion irregulare, H. occidentale, Inonotus dryophilus, and Onnia tomentosa.[4]
