Comments from Jim Ginns

Laetiporus conifericola Burdsall & Banik grew on a moss-covered, 45 cm diam Tsuga heterophylla log in Long Beach National Park, Vancouver Island, British Columbia.  The pileus was 12 cm across, glabrous, bright orange red, the flesh white, and pores bright yellow. The photo was taken in the heavily overcast, dark afternoon of September 21, 2001.

Our Sulphur Shelf has long been known locally as Laetiporus sulphureus but we now know that the true L. sulphureus does not occur in the Western United States and that the Sulphur Shelf that grows on hardwoods in California needs the new name L. gilbertsonii.  The Sulphur Shelf that grows on conifers in California is now called Laetiporus conifericola.   In the Sierras it is very common on Red Fir (Abies magnifica).
