Genera There are five genera in the Nidulariaceae: Crucibulum Fruiting bodies light tan to cinnamon-colored, cup- or crucible-shaped, and typically 1.5–10 mm wide by 5–12 mm tall. Cyathus Fruiting bodies vase-, trumpet- or urn-shaped with dimensions of 4–8 mm wide by 7–18 mm tall. Fruiting bodies are brown to gray-brown in color, and covered with small hair-like structures on the outer surface. Complex funicular cord. Mycocalia Small barrel- to lens-shaped fruiting bodies, usually 0.5–2 mm broad, that grow singly or in small groups. Nidula Fruiting bodies between 3–8 mm in diameter, 5–15 mm tall, and cup- or urn-shaped—having almost vertical sides with the lip flared outwards; color ranging from white, grey, buff, or tawny. Nidularia Typically 0.5–6 mm in diameter x 0.5–3 mm tall. They may be somewhat irregular in shape, or have a well-formed cup that is thin and fragile. No funicular cord.
