Corticolous and Saxicolous lichens in belvedere park, Paulo Afonso, Bahia state, Brazil: new occurrence records. In: Agrotrópica v. 32 n. 2 p. 85-96, 2020.

Abstract

Lichens are a diverse and complex group that can inhabit a wide variety of substrates. Taxonomic research of lichenized mycota are still very infrequent, although they are of significant relevance as indicators of mycodiversity. In order to fill that gap, this present research aimed to identify the corticicolus and saxixolous lichens found in Belvedere Park in the municipality of Paulo Afonso, Bahia State, Brazil. Specimens were collected from September/ 2017 through February/2018 on rocks and botanical substrates Cereus jamacaru DC. (mandacaru), Eugenia uniflora L. (pitanga), Licania tomentosa (Benth.) Fritsch (oiti), Mangifera indica L. (manga) and Mauritia flexuosa L.f. (buriti). The morphological features were examined macro and microscopically and identified based on the specialized literature. A total of 22 taxa were identified belonging to the genera Arthonia, Bacidia, Caloplaca, Chrysothrix, Diplotomma, Dirinaria, Haematomma, Lecanora, Parmotrema, Pertusaria, Pyxine e Xanthoparmelia. The lichens found and identified expand knowledge about the distribution data, introducing new fungal botanical hosts for science.
