Extract from Wikipedia article: Tarzetta cupularis is a species of apothecial fungus belonging to the family Pyronemataceae. This is a species of northern Europe with occasional records from further south in Spain and Morocco. It also occurs in North America. It appears from spring to autumn as brown to cream-coloured flask-shaped cups up to 2 cm across and 2.5 cm tall in groups in damp woodland. The related Tarzetta catinus tends to be larger with a more open cup, but the two species can only be reliably distinguished microscopically: by the shape of the spores (those of T. cupularis being narrower) and the paraphyses (those of T. cupularis lacking the distinctive lobed tips of T. catinus).
