Per Wu et al. (2012) citing Ito (1955) and Imazeki and Hongo (1989), this is a mushroom that is always said to be on mulberry trees.

[2] The Chinese name 桑黃 / 桑黄 is composed of 桑 ("mulberry tree") and 黃 / 黄 ("yellow").

[4] In Tonghua, Jilin, various mushrooms were seen as sanghuang by the locals, where it was used to treat cancer and stomach illnesses.

The report described the mushrooms and attached photos, but didn't identify them by Latin names.

[5] It had been long thought that this mushroom is Phellinus linteus, which is a view whose earlier iteration, that this mushroom is Phellinus yucatanensis, can be traced back to Japanese academic literacies in early 20th century based on specimens identified as Fomes yucatanensis, later deemed a synonym of P.

[2] Polyporus linteus is a species named by Miles Joseph Berkeley and Moses Ashley Curtis in 1860 with the specimen from Nicaragua.

[8] Zhou et al. (2015) examined two African specimens that morphologically fit X. rudis, and their sequences formed a distinct clade from P. linteus.
