Description: Masses of orange-pink, coral coloured spots of 4 to 10 mm in the anamorph form, called Tubercularia vulgaris Tode ex Fr.
These are conidia-producing fruiting structures, called sporodochia, which develop through cracks or natural openings in the spring and early summer. They range in size from 0.5-1.5 mm in diameter and height and look like minute raspberries. Young sporodochia are pink-orange to purplish-red when young, and become tan-to-brown or black as they mature. Later in the summer, orange-red coloured sexual fruiting structures, perithecia, form in groups around sporodochia. Perithecia are globose, approximately 0.4 mm in diameter, with a rough outer wall.
Biology: Saprophyte, living on dead plant tissue.
Habitat: branches of trees and shrubs, particularly on and around dead wood, mostly hardwoods, often Fagus.
Distribution: Northern Hemisphere.
