This is not a species of cypress but rather any cypress that has been attacked by a fungus that eats/rots out large channels in the wood that look like fat worm-holes. The fungus only attacks live trees and once a tree is cut down, no more peck occurs. The channels travel more or less up and down the tree so flat cut AND quartersawn planks show elongated channels, not holes, whereas a tree cut perpendicular to the length will show holes, not channels. This is illustrated by the first web pic below which shows such a cross-section.
my samples: NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K) colors will vary under other lighting conditions
