Figure 1. Ruddy panus on a stump. This is the morning of a
day following several rainy days.

Figure 2. The same stump and the same day as Figure 1.
but later in the afternoon. The sun came out and the colors
faded.


Figure 3. The caps that still have some violet color were
shaded by other caps that were removed for the photograph.

Figure 4. These fungi are quite persistent but in time the
specimens are all a drab ochraceous or tan color.


Figure 5. Caps are kidney- to fan-shaped or even funnel-
shaped as in these specimens.


Figure 6. One of the most conspicuous features is the
coarse hairiness of the caps.

Figure 7. Caps typically have an inrolled margin and
decurrent gills.

Figure 8. Closeup of an inrolled margin.

Figure 9. Stipes, when present, are also quite hairy.
