When sunlight is present the fruiting body is sent up into the tree and then spreads through the tree, this starts the decaying process of the tree. It was one of three new Laetiporus species published in 2001, which were distinguished genetically from the common Laetiporus sulphureus; the others were L. conifericola and L. huroniensis. My husband and I drank a glass or two of wine as well. Cooking time may be a factor, and some feel that Laetiporus growing on eucalyptus trees may contribute to digestive upsets, but both western species have been implicated.
