Ambrosia Maple is not a species of maple, rather it is a term that describes a distinctive figure common to soft maples produced by a beetle and a fungus. On infected wood, you will see small holes typically 1 mm in diameter. Surrounding the holes are greyish wisps of fungal stain that resemble puffs of smoke or flames. These puffs travel away from the hole up and down in a vertical direction. The overall look is unique; some woodworkers will like it, others may not.
