Macroscopic features
The fruiting bodies are composed of numerous tongue-shaped to fan-shaped hats that arise from a common, rooted stalk. The hats are usually layered on top of each other like roof tiles and are somewhat lobed. Laterally they narrow into a short, stem-like section.
The width of the sections is 6 to 20, the thickness 1 to 2 centimeters. When young they are yellow-brown to cinnamon-foxed, then dark-brown with a creamy-yellow edge. Old and injured they blacken. The surface is weakly zoned, tomentose, grainy on the edge, wrinkled at the base. The entire fruiting body becomes 20 to 50, in exceptional cases over 100 centimeters wide and up to 70 kilograms in weight. Thus it forms the largest and heaviest collective fruiting bodies in Central Europe.
The tubes, which are formed late, are short and white, the very short pores running down the stalk, white to pale yellow, blackening when touched. The flesh is white and first turns reddish in the air and later blackish. It smells spicy, older unpleasantly like mushrooms. It is soft and juicy only when it is very young, later fibrous and almost leathery with age. It tastes sour-bitter, the mushroom is only edible when young.
Microscopic features
The spores are broadly elliptical, smooth, 5 to 7.5 by 4 to 6.5 micrometers in size.
Ecology and phenology
The Giant Porling occurs from July to November at the base of the trunk, on stumps and roots of beech , oak , linden , horse chestnut , birch or other deciduous trees, rarely also on conifers. The saprobiont lives on dead wood in different stages of decomposition and is a weak parasite on damaged trunks. It causes intense white rot and mildew rot and is not uncommon.
