P. pini produces only one type of spores, basidiospores, which is also a type of sexual spores and the fungus overwinters as mycelium in diseased trees or dead trees. When decay is sufficient to provide enough resources, a new conk may be produced. Time from infection to conk production may be 10–20 years or more.
P. pini is characterized by producing only one type of spores, basidiospores, which are also sexual spores. The fungus survives the winter as mycelium in infected or dead trees. After sufficient decay, a new conk may develop. This process can take anywhere from 10 to 20 years or more.
