Tectella patellaris, commonly known as the veiled panus, is a species of mushroom in the family Mycenaceae.

The small, inconspicuous, dull brown mushroom is found in groups or clusters on the decaying wood of broad-leaved trees.

Tectella patellaris often lacks a true stem, but may include a very short one:[1] the stipitate point of attachment manifests as a lateral extension of the pileus, ranging from 0.1 to 0.3 cm.

[1] Tectella patellaris can be distinguished from other saprophytic, white-spored, pendulous species by the presence of its partial veil and unique lamellar attachment.

Tectella patellaris is widely distributed in North America and Europe and due to its inconspicuous and unassuming presence, may be more common than is reported.
