Grain Pattern
Irregular and wavy grain with heavy spalting, featuring zone lines and dark fungal coloration mixed with natural twisting contours.
Color & Appearance
Creamy white to light golden-brown background heavily contrasted by dark brown, grey, and black fungal lines (spalting zones). Moderate natural luster.
Hardness (Janka)
950 to 1450 lbf (Medium to Hard)
Durability & Decay Resistance
Non-durable; spalted woods have compromised structural integrity and are prone to decay if exposed to moisture.
Value & Sustainability
- Estimated Market Value
- 8.00 to 20.00 USD per board foot depending on figure intensity and form.
- Wood Age Estimate
- Relatively recent harvest (within the last few years), but the spalting process indicates the tree or log sat in damp conditions for months or years prior to drying.
- Sustainability Status
- Least Concern (abundant species), though highly figured spalted specimens are sourced opportunistically.
Common Uses
Decorative turning, carved sculptures, art pieces, custom furniture accents, and specialty veneer.
Geographic Origin
Eastern North America
Workability
Challenging due to varying hardness caused by fungal decay (spalting). Soft areas can crush while hard zones resist cutting, requiring very sharp tools and potential stabilization.
Finish Recommendations
Wipe-on varnish, shellac, or penetrating oils to enhance the contrast of the dark zone lines against the pale background.
Notable Features
Features distinct black demarcation zone lines created by competing fungi colonies within the decaying wood.
