The Tender Thujamoos ( Thuidium delicatulum ) is a diözisches moss from the kind of Thujamoose , because of their striking resemblance to the trees of life ( Thuja were named). It is similar to the floor moss ( Hylocomium splendens ), but has no annual shoots that are stacked on top of each other. The moss forms smaller blankets that appear matt. It grows both in forests and in poor grassland.

The stems are double-pinnate and are up to 8 cm long. The differently shaped leaves on the stems and branches are striking. The approximately 0.5 cm large stem leaves have a broad heart-shaped base and are short-pointed. Their tip consists of 1-2 cells. The rib of the stem leaves ends before the tip. The smaller branch leaves are serrated, their end cells are 2-4 pointed. As with the other species of the genus, the delicate thuja moss has a single papilla on each leaf cell , which makes the leaves appear rather dull.
There are numerous paraphyllia between the stem leaves . Each cell of the paraphyllia has a papilla in the middle.
The smooth, red sets are 2-2.5 cm long. The capsule is cylindrical and curved, the lid is beaked at an angle. The spore ripening takes place in autumn through winter. The spores have a diameter of 14-18 µm. The tender thuja moss rarely has any fruit.

Distribution and ecology
The tender thuja moss is almost cosmopolitan : It can be found in Europe from north to south. It is only rarer in the northern German lowlands. In Europe it mainly grows from the plains to low mountain ranges. It was also found in America and Asia.
The tender thuja moss prefers humus calcareous soils and occurs both on slopes of forest paths and in gutted lawns.
