dog's nose fungus |
Camarops petersii |
The dog's nose fungus is an apt name for this fungus. Initially the fungus has a papery brown skin over the surface of the spore producing surface, but this splits open to reveal a shiny, wet-appearing, tar-black surface that looks like a dog's nose. The fungus is a saprobe that can be found growing solitarily or in groups on decaying hardwood logs (e.g., oak, elm) in the summer and fall. Rotting Oak Log, Kendrick MetroPark, Allen County, Ohio. |

Ganoderma root and butt rot |
Ganoderma lucidum |
Lacquered polypore is parasitic on living hardwoods and a saprobe on the deadwood of hardwoods. On living hardwoods, it causes a white butt and root rot. It is unusual in that it is an annual rather than a perennial like many polypores. |
