Remarks (public):Irpicodon is by Pouzar referred to Corticiaceae. There are so far no clear limits for this family (as for all other large families of Aphyllophorales). In the wide sense used here, Irpicodon no doubt shoud be included in it. Where it should be placed within the family is an open question. Pouzar mentions Amylocorticium and Anomoporia as possible relatives, emphasizing the amyloid reaction, a character, however, of rather restricted value, as it appears in so many parts of the system. To us, Irpicodon seems to be rather isolated. The dense hymenial palissade reminds of the phlebioid fungi. The strongly developed tramal texture of more or less inflated and constricted hyphae has no real equivalent in Corticiaceae.
