Fungi of the genus Pholiota attack hardwoods and some conifers. They are among the major decay fungi but often are overlooked because the fruiting bodies last only a short time. Basswood, birches, poplars, and balsam fir are common hosts.
The conks are yellow or light-tan mushrooms that appear in late summer on decaying trunks, stumps and logs. The mushrooms appear in clusters and have caps with sticky upper surfaces, scales on both caps and stems, and grills beneath the caps.
In conifers, advanced decay has a mottled appearance--dark-brown streaks on yellow areas. If the wood is split along the grain, strands of mycelium may pull out, leaving pits in the wood. In hardwoods, decayed wood is whitish with tannish-brown streaks and white patches that became yellowish to rusty-red or brown.
