Wood-ear or tree ear (Chinese: 木耳; pinyin: mù'ěr, Korean: 목이 버섯), also translated wood jellyfish or tree jellyfish (Japanese: キクラゲ, Hepburn: ki-kurage), can refer to a few similar-looking edible fungi used primarily in Chinese cuisine; these are commonly sold in Asian markets shredded and dried.

• Auricularia heimuer (黑木耳, black ear fungus), previously misdetermined as Auricularia auricula-judae
• Auricularia cornea (毛木耳, cloud ear fungus), also called Auricularia polytricha
• Tremella fuciformis (银耳, white/silver ear fungus)

The black and cloud ear fungi are black in appearance and closely related. The white ear fungus is superficially similar but has important ecological, taxonomical, and culinary differences.

Other species in the genus Auricularia may be commonly called "wood ear" where they are found.

• Wood-decay fungus
