'''''Amyloporia''''' is a genus of five species of crust fungi in the family Polyporaceae. Its main distinguishing characteristic is the amyloid reaction of the skeletal hyphae, although some authors do not consider this to be sufficient to distinguish ''Amyloporia'' from the related genus ''Antrodia''.

==Taxonomy== The genus was originally circumscribed by Apollinaris Semenovich Bondartsev and Rolf Singer in 1941 as part of the subfamily Poroideae of the family Polyporaceae. Four species were included: the type ''Antrodia calcea'', ''A.&nbsp;crassa'', ''A.&nbsp;xantha'', and ''A.&nbsp;lenis''.<ref name="Bondartsev & Singer 1941"/> These mycologists later independently published the genus with a Latin description (establishing the validity of the publication in accordance with rules of nomenclature): Singer in 1944,<ref name="Singer 1944"/> and Bondartsev in 1953.<ref name="Bondartsev 1953"/> There has historically been much confusion about the true identity of ''A.&nbsp;calcea''.<ref name="Donk 1967"/> It is now classified in the genus ''Antrodia'' (family Fomitopsidaceae) as ''Antrodia calceus''.<ref name="Fungorum: Amyloporia calcea"/> Some authors have preferred to treat ''Amyloporia'' as synonymous with ''Antrodia''.<ref name="Ryvarden 1986"/><ref name="Ryvarden 1991"/> A molecular study published in 2010 determined that the five species then considered part of ''Amyloporia'' did not group together phylogenetically, and that ''Amyloporia'' was not worthy of generic status.<ref name="Yu 2010"/>

The generic name ''Amyloporia'' combines the Ancient Greek word {{lang|grc|άμυλον}} ("starch") and the name ''Poria''.<ref name="Donk 1960"/>

==Description== Bondartsev and Singer, in their description of ''Amyloporia'', emphasized the pore colour–initially white or colored, eventually becoming whiteish or often yellowish to slightly brownish; and amyloid trama in the adult fruit body. These features helped distinguish ''Amyloporia'' from the morphologically similar ''Ceraporus'' and ''Aporpium''.<ref name="Bondartsev & Singer 1941"/>

==Species== {{As of|2017|June}}, Index Fungorum accepts five species in ''Amyloporia'':<ref name="CoL-Fungorum"/> *''A. nothofaginea'' <small>Rajchenb. & Gorjón (2011)</small><ref name="Rajchenberg 2011"/> – southern Andes *''A. sinuosa'' <small>(Fr.)
