The following 24 new species of Trypetheliaceae are described after three weeks of fieldwork in an area with a radius of 50 km around Porto Velho in Rondônia: Astrothelium bivelum with astrothelioid ascomata, 5-septate ascospores with polar gelatinous caps, and a thallus without lichexanthone; A. curvisporum with bent, 5-septate ascospores of 115–135 × 29–36 μm with a 17–22 μm thick gelatinous layer; A. decemseptatum with pseudostroma that are essentially black and look like breaking through … Read more...

Aptroot A. & Cáceres M.E.S. (2017): New Arthoniales from Amapá (Amazonian North Brazil) show unexpected relationships - Lichenologist, 49(6): 607–615

Recent field trips to Amapá and the adjacent states of Amazonas and Pará uncovered unknown lichen species with unexpected relationships. The following new species of Arthoniales are described, mainly from Amapá in North Brazil: Neosergipea hyphosa, a corticolous species with an olive-green thallus, central part verrucose, marginal zone of 5–10 mm wide consisting of procumbent branching rhizohyphae, surrounded by a pinkish brown hyphal prothallus c. 3 mm wide into which the rhizohyphae protrude, … Read more...

Aptroot A. & Cáceres M.E.S. (2018): New lichen species from Chapada Diamantina, Bahia, Brazil - Bryologist, 121(1): 67–79

Nine species of lichens from Bahia are described as new: Arthonia saxistellata, Cladonia inflata, Cladonia lichexanthonica, Cladonia minisaxicola, Coniocarpon piccolioides, Pertusaria lichexanthofarinosa, Pertusaria lichexanthoimmersa, Pertusaria lichexanthoverrucosa and Physcia sorediiconvexa. Many of the new species contain lichexanthone in the cortex and the substance is reported for the first time from Cladonia. Keywords: Arthonia, Cladonia, Coniocarpon, Pertusaria, Physcia.

Aptroot A. & Cáceres M.E.S. (2014): A refined species concept in the tropical lichen genus Polymeridium (Trypetheliaceae) doubles the number of known species, with a worldwide key to the species - Nova Hedwigia, 98(1-2): 1-29

A refined species concept is applied in the tropical corticolous lichen genus Polymeridium (Trypetheliaceae). While up to now many species were considered to be variable in phenotypical characters, such as hamathecium inspersion and/or presence of lichexanthone, these characters are here accepted as species-specific characters. This classification is in line with the taxonomy in other groups of lichenized fungi. The monotypic genus Exiliseptum is included here in Polymeridium, as it differs in only … Read more...
