The microscopic structure of conifer wood consists of two types of cells: parenchyma, which have an oval or polyhedral shape with approximately identical dimensions in three directions, and strongly elongated tracheids. Tracheids make up more than 90% of timber volume.

Auricularia americana is a wood-rotting species, typically found on dead attached or fallen wood of conifers. It is widely distributed in North America (primarily in the Northeast, between April and September) [3] and is also known from China and the Russian Far East .
conifers (Coniferae): there are approximately 600 known species of conifers. [9] All species have secondary xylem, which is relatively uniform in structure throughout this group. Many conifers become tall trees: the secondary xylem of such trees is used and marketed as softwood .

Callitropsis nootkatensis is an evergreen conifer growing up to 40 meters (131 ft) tall, exceptionally 60 m (200 ft), with diameters up to 3.4 to 4 m (11 to 13 ft). The bark is thin, smooth and purplish when young, turning flaky and gray. [4]
A. ostoyae is common on both hardwood and conifer wood in forests west of the Cascade Range in Oregon, United States. It has decurrent gills and the stipe has a ring. [1] The mycelium invades the sapwood and is able to disseminate over great distances under the bark or between trees in the form of black rhizomorphs ("shoestrings"). [2]
