. Species are typically hoof-shaped (ungulate). New growth each season is added to the margin, resulting in a downward extension of the hymenium

Hymenium

The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia or...

. This often results in a zonate appearance of the upper surface, that is, marked by concentric bands of color.
