Daldinia concentrica, commonly known as the King Alfred's Cake or Crumble Fungus, is a distinctive species of fungus found in the Comunidad Valenciana. Known locally by names such as Tizón, this unique fungus is notable for its striking appearance and interesting ecological role.

This fungus primarily grows on deadwood, favoring tree species like ash, beech, and occasionally oak. It plays a crucial role in the ecosystem by aiding in the decomposition of dead trees, thereby contributing to nutrient cycling in the forest.

• Appearance: The fruiting body of Daldinia concentrica is spherical and can range from 2 to 7 cm in diameter. The exterior is usually blackish-brown and sometimes shiny, while the interior consists of concentric layers that resemble the rings of a tree when sliced open.
• Habitat: Preferring temperate climates, this fungus is commonly found growing on the dead wood of broadleaf trees in woodland areas within the region.
• Uses: While not edible for humans, Daldinia concentrica has been historically used as a natural fire starter once dried, due to its ability to catch and hold an ember efficiently.
• Ecological Importance: As a saprophytic fungus, it contributes to the breakdown and decay of organic material, thus playing a vital role in forest health and regeneration.

While not often sought after by mycologists for culinary purposes, Daldinia concentrica remains a fascinating subject of study due to its unique characteristics and ecological significance.
