Specimen #14 Fungi

Specimen 14: Fungi

Figure 1: The specimen was found on the side of a dead hardwood stump.

Figure 2: The radial wrinkles can be see in the specimen. It is brown in color, and is darkening/bruising with age as it is stored. The specimen appears woody, and tougher due to age.

Figure 3: The underside of the specimen shows the visible tubes (pores), and the lack of stalk. The pores were initially white and darkened with age. 

Figure 4: The deep, elongated tubes forming a united layer can be seen pictured above.

Key Steps:

• Key to major groups of fleshy fungi --> pp. 52
• Fruiting body shelflike, crustily, tough, woody, layer of pores under cap --> Polypores & Bracket Fungi pp. 549
• Spore-bearing surface not composed of tubes, or if composed of tubes then the tubes form a united layer, fruiting body fleshy, tough, woody --> 2
• Stalk absent, growing on wood, fruiting body knoblike, hooflike, bracketlike, shelflike, crustily --> 4
• Pore surface exposed, not growing on birch --> 5
• Pore surface differently colored (not pinkish/reddish-purple/blackish-purplish) --> 6
• Fruiting body not rescpindle, has cap --> 7
• Spore-bearing surface with deep, elongated, mazelike pockets or even gills or "teeth" --> 8
• Spore-bearing surface with tubes (pores), elongated or mazelike --> 10
• Fruiting body annual (with only one tube layer), cap soon dark to brown to blackish, often roughened, radially wrinkled, fruiting body at first watery and often beaded with droplets, but tougher in age, pore surface whitish at first but aging or bruising darker, found on dead trees, widespread but not common --> Ischoderma resinosum pp. 573

Ecology:
This species is often found on the deadwood of hardwoods or conifers, usually appearing in fall (Kuo, 2004). They tend to cause a rot that separates the rings in aging wood (Kuo, 2004). It is found very widely distributed in North America (Kuo, 2004).
