Veiled Panus

Tectella patellaris

"Tectella patellaris" is a species of mushroom in the Mycenaceae family. The small, inconspicuous, dull brown mushroom can be found in groups or clusters on the decaying wood of broad-leaved trees. Young specimens are easily recognized by the presence of a partial veil, as there are no other agarics that lack a stipe and have a partial veil.

Appearance

The cap may be somewhat viscid when wet. Dimensions of the cap are approximately 0.5-2.0 cm across. The fruit body is generally small, brown, and clamshell-shaped. "Tectella patellaris" lacks a true stem. The stipitate point of attachment is short and manifests as a lateral extension of the pileus. The gills radiate from this central point of attachment. This mushroom is saprobic and found on fallen logs of hardwoods in North America and Europe. The specific epithet "patellaris" means "dish shaped". The mushroom is commonly known as the "Veiled Panus". The snuff brown gills of young specimens are covered with a buff white ephemeral partial veil that may be absent in older specimens. The spore deposit from "Tectella patellaris" is white.The spores are 3-5 × 1-1.5 µm, smooth, and cylindrical, and weakly amyloid. Spores are white in mass. Cheilocystidia are present on gill edges.

Naming

"Tectella patellaris" can be distinguished from other saprophytic, white-spored, pendulous species by the presence of its partial veil and unique lamellar attachment. "Panellus stipticus" is tougher, lacks the partial veil, and is luminescent. "Crepidotus mollis" and "Crepidotus applanatus" are brown-spored.
