Lyromma
Introduction '''''Lyromma''''' is a genus of foliicolous (leaf-dwelling) lichens, and the sole member of '''Lyrommataceae''', a family in the order Chaetothyriales. The genus was circumscribed in 1965 by Brazilian mycologists Augusto Chaves Batista and Heraldo da Silva Maia, with ''Lyromma nectandrae'' assigned as the type species. The family was proposed by Robert Lücking in 2008.Characteristics of the genus include the spherical to short barrel-shaped perithecia and elongated barrel-shaped pycnidia, and smooth thalli (lacking a cortex) of rounded patches formed by its symbiotic relationship with green algae from the genus ''Phycopeltis''.
