'''''Buglossoporus''''' is a genus of fungi in the family Fomitopsidaceae. The genus was circumscribed in 1966 by Czech mycologists František Kotlába and Zdeněk Pouzar, with ''Buglossoporus quercinus'' as the type species.<ref name="Kotlába 1966"/> In some works, ''Buglossoporus'' has been treated as a synonym of ''Piptoporus''.<ref name="Ryvarden 1991"/><ref name="Hattori 2000"/>

''Buglossoporus magnus'', known from only three locations in old growth lowland rainforest of Peninsular Malaysia, is considered a vulnerable species by the IUCN, and appears on their Red List.<ref name="IUCN"/>

==Description== The fruit bodies of ''Buglossoporus'' are annual. They have a cap, and a variable attachment to the substrate—in some species the cap is attached directly, while others have a stipe. The cap surface ranges in colour from pink, cinnamon, orange to brown, with a texture that is either felt-like or smooth, without zone lines. The pore surface on the cap underside is white, cream, buff to brown. Pores are small, with a round to angular shape. The context is white, cream, buff, orange to brown, corky, and thicker than the tubes. It sometimes has a pellicle (a thin membrane) at the upper surface. The tubes are thin and fragile.<ref name="Han 2016"/>

''Buglossoporus'' has a hyphal system that is dimitic in the context, but monomitic in the trama. Generative hyphae have clamp connections, while the skeletal hyphae are thick-walled. There are no cystidia in the hymenium, but thin-walled cystidioles are typically present. Spores produced by ''Buglossoporus'' range in shape from ellipsoid, to cylindrical, to spindle-shaped. They are hyaline, thin-walled, and smooth, showing no reaction to Melzer's reagent. The fungus grows on angiosperm wood and causes a brown rot.<ref name="Han 2016"/>

Molecular phylogenetic analysis shows ''Buglossoporus'' be closely related to ''Neolentiporus''. This latter genus, however, has a dimitic hyphal system in trama with irregularly thick-walled generative hyphae, and skeletal hyphae that are metachromatic.<ref name="Han 2016"/>

Kotl. & Pouzar (1966)}}

In a later study of Corner's Asian and West Pacific collections, Tsutomu Hattori concluded that both ''B.&nbsp;brunneiflavus'' and ''Buglossoporus flavus'' were "dubious species" due to "poor or sterile conditions", and that ''Buglossoporus matangensis'' and ''B.&nbsp;rufescens'' are synonyms of ''B.&nbsp;malesianus''.<ref name="Hattori 2000"/> This latter synonymy was supported in a 2016 study.<ref name="Han 2016"/>
