Extract from Wikipedia article: Tarzetta catinus is a species of apothecial fungus belonging to the family Pyronemataceae. This is a largely European species with a few records from Mexico and the United States. It appears from spring to autumn as cream-coloured cups up to 5 cm across, usually in small groups among broad-leaved trees, especially beech. The rather similar Tarzetta cupularis is usually a smaller, deeper, flask-shaped cup, but the two species can only be reliably distinguished microscopically: by the shape of the spores (those of T. catinus being broader) and the paraphyses (those of T. catinus having distinctive lobed tips).
Tarzetta catinus is a species of fungus in the family Pyronemataceae. It is a small to medium-sized cup fungus with a brown to reddish-brown inner surface and a whitish to pale brown outer surface. In St. Petersburg, Leningrad Oblast, and north-western Russia, Tarzetta catinus has been found growing on soil, moss, and decaying plant material in coniferous and mixed forests. Fruitings typically occur from late summer to early autumn. The fungus is considered rare in the region, with scattered records from various localities.
