1. Genus: Avrainvillea Decaisne, 1842
Thallus is robust, erect, light brown to dark, with greenish and gray tones, solitary or forming groups, consisting of a bulbous appressorium. Stipe is cylindrical or flattened and unbranched. Blade is sessile or pedunculated, flabelliform, clavate, spatulated, orbicular or lobed, distinctly zonate or not, rounded edges, often broken or eroded. Appressorium is composed of entangled, straight, tortuous or moniliform siphons, and rounded, acuminate, flat, or clavate apices. Stipe and blade are made formed from densely woven cylindrical siphons that are branched dichotomously, with deep or superficial constrictions above the dichotomies, no side branches or appendages. Siphons are straight, tortuous, or moniliform, ranging from being of one type or being a combination, or even a single filament in a various forms; apices of siphons are rounded, acuminated, clavate, or falciform.
