Gloeoporus dichrous (Fr. : Fr.) Bres.

Hedwigia 53: 506 (1912)

gelatinous-pored polypore; bicoloured bracket (UK)
Annual, effused-reflexed. Upper side and margin white. Lower side reddish brown, salmon-colored, with small shallow pores. When fresh, the gelatinous to rubbery pore layer can be stretched and separated from the white underside of the cap tissue. Microscopic characters: hyphae with clamps; cystidia absent; spores allantoid (curved like a sausage) to cylindrical.
Similar species:
Gloeoporus taxicola grows on conifers and is effused with a white margin but no projecting cap; hyphae lack clamps, hymenium has pointed cystidioles (sterile cells similar in size to basidia).
White rot on hardwoods, rarely conifers. Reported to be found on dead polypores.
For Chicago Region can be found from May to November.
Widespread across North America.
Chicago Region status:
Fairly common. Widespread.
Ginns (2014, PDF) gives no explanation for his new combination in Gelatoporia. DNA phylogenies argue against this placement. See the Genus Gloeoporus page.
