In Polypo7'us ajpplan- atiis the strata are deeper and very clearly differentiated. They are also of a dark gray, or hair- brown color, while the tube strata of Polypoymsphiicola are whitish or yellowish-brown, and while clearly differentiated are not so distinctly so as in Polyporus apjylanatus. The fruit bodies of Polyporus p)inicola are sometimes found on the trunks of living trees, but nuich more frequently they do not appear until the tree is dead. They are quite common on dead standing trunks and stumps and on fallen logs. They continue to grow after the tree is dead and in quite an advanced stage of decav. In wood which is in quite an advanced stage of decay exten- sive sheets of mycelium forming " punk " are often in the crevices formed by the checking of tlie wood. These sheets of punk are very similar to those formed by Polyporus sulpliiireus in decidu- In the larffe number of cases in. 84. — " Dozed" "place in bu tt of red spruce from mycelium of Tra- metes ahietis^ ous as well as in cojiiferous trees. winch T have found these sheets of punk in rotten logs or decay, ing tree trunks of conifers in the Adirondack mountains, I have not found any fruit bodies of the Polyporus sulpJmretts.
