Cryptoporus volvatus (mgw-04)

Latin name: Cryptoporus volvatus (Peck) Shear
French name: Carie rouge du pied et carie de l'aubier
Division: Basidiomycota
Class: Aphyllophorales

Micro-habitat(s)
Trunk

Distribution
Canada

Damage, symptoms and biology
The annual, semi-circular fruiting body has a membrane that covers the tubes. It resembles a pouch or small bag.

Grey sap rot develops rapidly in dead standing trees but is quite superficial, limited to the outer 1 to 2 cm of sapwood. As a result, little or no board-foot volume loss is associated with this decay.

Other information
Fruiting bodies usually develop the year after tree death occurs, and often form by the hundreds up the stem (Fig. c). On Douglas-fir, C. volvatus is often associated with old bark beetle galleries and can be used as an indicator of bark beetle kill. Sporophores of Cryptoporus volvatus could be confused with immature conks of other polypore fungi. The latter, however, are solid rather than "pouch-like." Insects have been shown to play a role in the dissemination of C. volvatus basidiospores.

Symptoms/Signs:  C. volvatus produces small, cream-colored to tan, leathery fruiting bodies. The most distinguishing feature of C. volvatus is that it has a fungus sheath with a single hole covering the lower spore-bearing surface. This is not a heart-rot fungus, but causes a grayish white rot of the sapwood of recently killed trees.

Biology:  Insects enter, feed, and then exit fruiting bodies of the pouch fungus, carrying spores to infect recently killed or dying trees. Typically, it occurs only on dead trees and snags within 1 to 2 years after the tree’s death.

Effects:  Most commonly found on ponderosa pine in the Southwest, but can infect other conifers. This is not an aggressive pathogen, but invades a tree within the first 2 years of death. This fungus is very common in trees killed by bark beetles.
Similar Insects and Diseases:  No other conifer pouch fungus has been identified.
