Gloeoporus dichrous
[Caloporus dichrous]
- Name
- gelatinous-pored polypore; bicoloured bracket (UK)
- Etymology
- Epithet = two-colored. Genus = glutinous-pore.
- Fruitbody
- 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).
- Ecology
- White rot on hardwoods, rarely conifers. Reported to be found on dead polypores.
- Phenology
- For Chicago Region can be found from May to November.
- Biogeography
- Widespread across North America.
- Chicago Region status
- Fairly common. Widespread.
- Specimens examined
- Our Chicago research database has more than 50 collections and 25 observations for the past 20 years.
