What You'll Learn
Black Fungus vs. Wood Ear: Appearance
When comparing Black Fungus and Wood Ear mushrooms based on appearance, it’s essential to note that they are often confused due to their similar dark coloration and gelatinous texture. However, upon closer inspection, distinct differences emerge. Black Fungus, scientifically known as *Auricularia polytricha*, typically appears as a dark brown to black, ear-shaped fruiting body with a slightly wavy or ruffled edge. Its surface is smooth and shiny, often resembling dried leather when not rehydrated. In contrast, Wood Ear, or *Auricularia auricula-judae*, shares the ear-like shape but tends to be slightly thinner and more delicate in structure. While both belong to the same genus, Wood Ear often has a more uniform, velvety texture compared to the slightly firmer Black Fungus.
One of the most noticeable differences in appearance is their size and thickness. Black Fungus is generally larger and meatier, with a more substantial body that can grow up to 10 centimeters in diameter. Wood Ear, on the other hand, is smaller and thinner, usually measuring around 2 to 8 centimeters across. This size disparity makes Black Fungus more prominent in dishes, while Wood Ear is often used for its subtle, crunchy texture. Both mushrooms are dark in color, but Black Fungus leans more toward a deep, almost black hue, whereas Wood Ear may appear slightly lighter, with a dark brown or grayish tone depending on its maturity.
The undersides of these mushrooms also differ subtly. Black Fungus typically has a smooth, almost featureless underside, which contrasts with its slightly ruffled edges.
