Importance and distribution
Polypyrenula comprises only one species known from the type collection growing on Croton cascarilla in Caribbean (Fée 1837), and from new collections made by Miranda-González et al. (2020) from North America (Pacific Coast of Mexico) and in South America (Bolivia) suggesting a Neotropical distribution of the genus, particularly dry areas and tropical forests. Polypyrenula is associated with the following phorophytes: Apoplanesia paniculata (Fabaceae), Caesalpinia caladenia (Leguminosae), Gliricidia sepium (Fabaceae), Heliocarpus pallidus (Malvaceae) and Leucaena lanceolata (Fabaceae).
