| 1241667 | Symptoms | These young ponderosa pines have been killed by annosus root disease. The hollow pine stump is a good indicator of annosus root disease root disease in this stand. Infected roots of this stump may extend 50 feet or more from the stump base. |
| 1241674 | Symptoms | An useful sign of annosus root disease is an irregular pattern of staining in root and butt heartwood. In firs, the stain varies from dull gray, to reddish-purple. |
| 1241675 | Symptoms | An useful sign of annosus root disease is an irregular pattern of staining in root and butt heartwood. In Douglas-fir the stain is red-brown. |
| 1241676 | Sign | Button conks; tiny, poorly formed conks of Heterobasidion annosum are sometimes found near the root collar of killed seedlings. They are also found on small roots of larger trees. |
| 1241677 | Fruiting Bodies | Annosus root disease often is diagnosed by looking in hollows of nearby stumps where the conks are found. The surface is gray or brown. |
| 1241678 | Fruiting Bodies | Annosus root disease often is diagnosed by looking in hollows of nearby stumps where the conks are found. The lower surface has tiny pores and is cream colored. |
| 1241679 | Symptoms | Advanced decay has irregular white pockets and black fleck. It is soemwhat laminate at the beginning but eventually becomes stringy and spongy. |
| 1241680 | Feature(s) | One means of identifying annosus root disease is to incubate freshly cut sections of infected wood in a plastic bag to stimulate production of the asexual stage, Spiniger meineckellum (40x). |

| 1409068 | Research | CODIT is also applicable to root rots. A tree either rapidly stops the spread of infection, as shown in this pine infected by Fomes annosus, or it does not, letting the infection girdle and kill the root or butt. A cross-section was cut near the top of the dead area.... |
