The spore case enclosed by the endoperidium has no stalk , and is opened at the top by a tear or pore. Microscopically, sterile cells, long-threaded cells called capillitium originate from the inner surface of the peridium; they are highly branched and interwoven. The spores are large, spherical, minutely warted, and brown. [5]
The rays have an irregularly cracked surface, while the spore case is pale brown and smooth with an irregular slit or tear at the top. The gleba is white initially, but turns brown and powdery when the spores mature. The spores are reddish-brown and roughly spherical with minute warts, measuring 7.5–11 micrometers in diameter.
In Common Smoothcap moss (Atrichum undulatum), the vibration of sporophyte has been shown to be an important mechanism for spore release. [15] In the case of spore-shedding vascular plants such as ferns, wind distribution of very light spores provides great capacity for dispersal. Also, spores are less subject to animal predation than seeds ...
The outer tissue layer splits to form star-like rays and expose a circular spore case. Inside the spore case is the gleba—fertile spore-producing tissue that is white and firm when young, but becomes brown and powdery in age. The grayish-brown spore case is set on a short, slender stalk, and has a well-defined narrow pore at the top where ...

Spore Origins is the mobile phone/iPhone [89] /iPod [90] spinoff of Spore, and as with the Nintendo DS version, focuses on a single phase of gameplay; in this case, the cell phase. The simplified game allows players to try to survive as a multicellular organism in a tide pool , similar to Flow . [ 91 ]
Columella (in plants) is an axis of sterile tissue which passes through the center of the spore-case of mosses. [1] In fungi, it refers to a centrally vacuolated part of a hypha, bearing spores. The word finds analogous usage in myxomycetes. [citation needed]
These spots are called "sori" and consist of masses of spore cases, called sporangia. [9] On Polystichum vestitum the spores are monolete and bilaterally symmetrical located which gives them unique identification. [10] When the spores are ripe, the sporangia is torn apart and the light-weighted spores are carried away with the wind. [11]
