General Description

Cryptoporus volvatus is a polypore put looks like a gasteromycete since the cap margin has extented tissue that completely encloses the pore surface. Rather than having the normal appearance of a polypore, this looks similar to a puffball going on a conifer.


The name Cryptoporus means “hidden pores.”


Spores are spread by the employment of insects that bore into the membrane covering the pores where the spores are held. The spores are transfered to the next host on the bodies of the insects which bore beneath the bark.


C. volvatus causes a soft grayish brown rot towards the outside of sapwood.


Also called the veiled polypore or the cryptic globe fungus. The veil is broken open by insects and small arthropods boring holes into the membrane.

 Peck originally named this as Polyporus volvatus
