Bracket fungus basidiocarp (fruiting body)lower surface showing skeletal (edge) and generative hyphae (gill, spore producing). Magnification 4, scanning electron microscopy. Bracket fungi form shelf-like fruiting bodies on elevated positions like rotting tree trunks. Reproductive spores are dispersed through pores in the surface of the brackets.

Cyanobacterium - Nostoc spp.

Cyanobacterium (Nostoc spp.). Gram-negative, oxygenic, photosynthetic, filamentous cyanobacterium (prokaryote). Magnification 4560, scanning electron microscopy. Note the thylakoids (photosynthetic membranes - green), polyhedral bodies (brown) and lipids bodies (yellow). Lichens often are associated with Nostoc in a symbiotic relationship. Specialized cells in the Nostoc filament, called heterocysts, fix atmospheric nitrogen gas into amino acids and thus progressively enrich the soil with nitrogen for plant growth.

This bacteria is a cocci, gram-positive, facultative anaerobic organism. It is a human pathogen that causes pneumococcal disease. Infection can occur at various parts of the body including ears, sinus, brain, spinal cord, lungs and blood. Symptoms depends on the location of the infection and range from mild to severe and may include coughing, chest pain, shortness of breath, fever, stiff neck, sensitivity to light, ear pain, irritability, confusion, disorientation, joint pain, sleeplessness and chills. Infection is spread via sneezing, coughing and proximity to an infected individual.
