This page describes and illustrates the terminology used throughout the lichen trail. apothecium) are the reproductive structures of the mycobiont (fungal partner), containing the spores produced by the fungus. Introduction. Ascospores are formed in the apothecia and dispersed by wind to infect flowers (Abawi and Grogan 1979; Natti 1971; Purdy 1979).The most speciose genera in the family are the well-known groups: Xanthoparmelia (822 species), Usnea (355 species), Parmotrema (255 species), and Hypotrachyna (262 species).nehcil adileg sispocalP . Occurs statewide and is common in cities. rubicunda, lacks apothecia and is wholly, or partially red. In a lichen this tissue surrounds the sexual organs and gives rise to the fungal spore-producing structures (such as apothecia). The causal fungus overwinters on the ground, and in spring produces a cup-shaped mushroom that releases spores.
