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).

Tarzetta cupularis is a species of fungus in the family Pyronemataceae, characterized by its small to medium size, cup-shaped to saucer-shaped fruiting body, and whitish to pale brown color. In East and Central Texas, it typically grows on the ground in wooded areas, often associated with rich soil and decaying organic matter. The fungus produces ascospores that are elliptical in shape and measure 12-18 x 6-8 μm. It fruits from spring to fall, with peak activity during the wetter months. Specimens have been collected in various counties, including Bastrop, Brazos, and Travis, often in areas with abundant leaf litter and shade.

Toothed cup fungus (Tarzetta cupularis) in cross section on Caney Creek Trail (Little Lake Creek Loop Trail) in Sam Houston National Forest north from Montgomery. Texas, February 29, 2020Little Lake Creek Loop Trail, Montgomery, TX 77356, USAObservations of Tarzetta cupularis in East and Central Texas reveal that the fungus grows under pines and oaks, particularly on slopes near creeks. On Caney Creek Trail in Sam Houston National Forest, the fungus was found under pine needles and oak leaves on February 29, 2020. Detailed views show the fungus's distinct toothed cup shape, with observations including upper, side, and close-up views. A cross-section of the fungus was also observed. The fungus appears to thrive in the forest environment, with multiple sightings on the same trail. The specific location and timing of the observations suggest that Tarzetta cupularis may be commonly found in this region during late winter. The variety of views and details observed provide a comprehensive understanding of the fungus's morphology and habitat in East and Central Texas.
