Eopyrenula

Eopyrenula is a genus of lichen-forming fungi in the family Dacampiaceae. It comprises six species. The genus was established in 1973 by Richard C. Harris to separate these lichens from the related genus Pyrenula, based on differences in their reproductive structures and spore characteristics. Eopyrenula species are found on tree bark in temperate regions, particularly in Europe and North America, where they form thin, pale grey crusts dotted with tiny dark fruiting bodies. The genus occupies an uncertain position in fungal classification, with its family placement remaining provisional pending molecular analysis. These inconspicuous lichens can be identified by their brown, multi-segmented ascospores and their association with the green alga Trentepohlia....read more on Wikipedia.
