Hyaline cartilage is the glass-like (hyaline) but translucent cartilage found on many joint surfaces. Typical histological presentation involves diffuse alveolar damage and hyaline membrane formation in alveolar walls. The hyphae colour appears to be hyaline or lightly pigmented. They have two pairs of membranous wings that may be hyaline, cloudy, or pigmented. Both joint surfaces are covered with a strong but lubricated layer called articular hyaline cartilage. The nasal septum contains bone and hyaline cartilage. The spores are smooth, hyaline, long-filiform, and often septate. Spores narrowly ellipsoid to allantoid, hyaline, smooth. Damaged hyaline cartilage is usually replaced by fibrocartilage scar tissue. These cells typically differentiate into fibrocartilage and rarely form hyaline cartilage. The fibroblasts within the granulation tissue develop into chondroblasts which also form hyaline cartilage. These cells may be yellowish or clear (hyaline). They are elliptical, smooth, sometimes curved, and appear hyaline (translucent) to yellowish. Hyaline cartilage is the most prevalent type of cartilage. Perichondrium can be found around the perimeter of elastic cartilage and hyaline cartilage.
