Rumbold (626) discussed the interrelationships of bark 
beetles and blue-staining fungi. Bramble and Holst (95) discussed 
the fungi associated with the southern pine beetle in killing short- 
leaf pines. Nelson (563) reported the effect of blue-staining fungi 
on southern pines attacked by bark beetles. 
Several species of ambrosia beetles carry staining fungi on 
their bodies and, since they attack hardwood logs and lumber in 
ee are considered to be important stain disseminators
