It seems due to the lignicolous fungi (Ascomycetes class); it can be a bright blue to black. Apparently it does not, by itself, impact the woods cellular components thus its mechanical properties are retained. However, it does make the wood more permeable to moisture and therefore more vulnerable to another fungus, lignivorous, which does later decompose the wood.

I’ve been seeing samples of this deep blue-green (birch?) wood and I was wondering if this is considered spalting by fungi or if there is an other cause. Any ideas out there?

Fun math fact: 19937 is prime even when you take the end digit and put it back at the start repeatedly. It's known as a circular prime:

19937 = prime
71993 = prime
37199 = prime
93719 = prime
99371 = prime

It's also one of the 52 known Mersenne prime p-values (2^p-1), as 2^19937-1 is prime, and this Mersenne prime is the most common used period length for the Mersenne Twister pseudorandom number generator.

If I can tell your alt text is AI—such as, for example, it’s inaccurate—I’m not going to boost your image, no matter how much I like it. If you must rely on a slopbot, at least make sure it actually describes what’s in the image FFS.

Such a nice profile of the #AssistiveTech work being done by my Boston College Physical Computing students. https://www.bc.edu/content/bc-web/sites/bc-news/articles/2026/spring/the-class-that-makes-a-difference-.html May be interesting to folks in the #CSed #MakerSpace #RaspberryPi and #CircuitPython communities.
