The hemolysis is called green hemolysis because of the color change in the agar.

Frimbriae are structures related to Gram-negative bacteria. S. Pneumoniae, however, is Gram-positive. Therefore it does not have fimbriae.
Has a capsule
Bacterial pneumonia is typically caused by organisms such as Streptococcus pneumoniae, Haemophilus influenzae, and Mycoplasma pneumoniae. These bacteria can have different Gram stain characteristics: S. pneumoniae is Gram-positive, H. influenzae is Gram-negative, and M. pneumoniae lacks a cell wall and is therefore classified as "neither" in Gram staining.
The S strain produces a capsule but the R strain does not
Blood agar is considered a differential medium because it can differentiate between microbes based on their ability to hemolyze red blood cells. Some bacteria are able to break down red blood cells, leading to distinct patterns of hemolysis (such as alpha, beta, or gamma hemolysis) that can be used to identify and classify bacteria. This characteristic makes blood agar useful for identifying and characterizing different bacterial species.
Streptococcus pneumoniae, also known as pneumococcus, is a gram-positive diplococci bacteria that can cause septic meningitis in individuals. It is a common cause of bacterial meningitis in adults.

Almost always - stress on 'almost'. There are sporadic cases of nonhemolytic or alpha hemolytic S. pyogenes. So beta hemolysis is usable for quick screens, but is not 100% percent reliable.
