Summary
Five new species ofCeratocystis wood staining fungi are described. The speciesCeratocystis abiocarpa is common in recently killed subalpine fir (Abies lasiocarpa (Hook)Nutt.), trees or felled logs in the Central Rocky Mountain area from Wyoming to Northern Arizona and New Mexico. It also occurs commonly in Engelmann spruce (Picea engelmannii Perry) logs infested withIps sp. bark beetles in this same area.
C. minuta-bicolor is widespread in beetle infested logs of spruce, firs, pines and other conifers.C. nigrocarpa was isolated only occasionally but is apparently rather widespread in bark beetle infested pine logs.C. leucocarpa was isolated only occasionally from beetle infested pine logs and rarely in other conifers. It has been encountered mainly in the Fort Collins, Colorado area and from southern Oregon.
The fifth new species (C. seticollis) was isolated only once from ambrosia beetle galleries in sapwood of a hemlock stump in eastern New York state.
