layer of tubes, and a
yellowish brown or darker brown Context

 

1. Basidiocarp with more or less of a distinct stem

    2. Upper surface of basidiocarp covered with a red varnish; only on hardwoods.................Ganoderma lucidum

    2. Upper surface not varnished; only on conifers, mostly stipitate on ground from roots; context
        of uniform texture, not of two layers of different consistency .........................................Phaeolus schweinitzii

1. Basidiocarp not with a stem but of the bracket type (sessile)

    3. Upper surface of basidiocarp red varnished ........................................................Ganoderma lucidum

    3. Upper surface not red varnished

        4. Growing only on conifers

            5. Pileus tomentose, soft when fresh, brittle when dry ...........................................Phaeolus schweinitzii

            5. Pileus glabrous; corky or leathery ....................................................................Fomitopsis cajandera

        4. Growing on hardwoods

            6. Basidiocarp a more or less globose mass, with many small,
                closely overlapping pilei ..............................................................................Globifomes graveolens

            6. Basidiocarp a single bracket or a few overlapping pilei

                7. Inner substance of basidiocarp tannish to ochraceous; pore surface white and
                    bruising brown.........................................................................................Ischnoderma resinosum

                7. Inner substance yellowish brown or darker brown; pore surface not white and bruising

                    8. Basidiocarp turning violet where touched with KOH ...........................Hapalopilus nidulans
        
                    8. Basidiocarp turning black or darker (but not violet) where touched with KOH solution

                        9. Basidiocarp 2.5 - 15 cm wide and up to 2 cm thick; on various dead hardwood
                            species; upper surface dark, rusty brown to black with age, velvety at least on yellow-
                            ochre growing margin ..........................................................................Phellinus gilvus

                        9. Basidiocarp up to 35 cm wide and 10 cm thick; mostly at base of living oak (Quercus) trees
                            causing a butt and root rot; upper surface yellowish-brown, becoming dark brown and
