(1891) Meruliporia incrassata is a fungus that creates dry rot, predominantly in North America, where it can also be known by the diminutive "poria", which is also a recognized historical synonym for the genus.

[1] M. incrassata has a wide range of favourable temperatures, growing aerobically from the freezing point to approximately 38 degrees Celsius, by consuming cellulose but not lignin.

[2][1] While it is known as "dry rot", this is a misnomer linked to the resulting decay of the wood being powdery and cracked; the fungus, like many fungi, does require moisture.

[4] It's behaviour mirrors that of the other dry rot fungus Serpula lacrymans, which is more prevalent in Europe and extant in the northern United States.

[4] It seems to have spread substantially in the middle of the 20th century, coinciding with importation of softwood, but its origin is unknown, as it was found in the American South, Northeast, and Pacific Northwest.
