| Resumo: | Gomphillaceae is considered one of the most diverse families of foliicolous lichens. The
objective of the present research is to review the family Gomphillaceae (Ascomycota
lichenized), especially the foliicolous taxa, using morphological and molecular characters.
The methodology consisted of using samples collected in areas of Atlantic Forest, Brejo de
Altitude and Amazon, in Brazil, in addition to samples collected in other Latin American
countries such as Cuba, Mexico, Panama, Costa Rica and Guatemala. The collected material
was pressed, refrigerated, analyzed and selected according to the presence of representatives
of the family Gomphillaceae. After that, the samples were identified, morphologically
reviewed and molecularly analyzed using the mtSSU rDNA and nuLSU rDNA markers. A
total of 2,127 leaves containing foliicolous lichens was collected and 502 specimens were
selected for identification and molecular analysis. However, 309 specimens were used in the
final phylogenetic analysis for the family, added to 28 sequences from GenBank (including
the outgroup). A total of 464 sequences were obtained for the Gomphillaceae family, 272 new
for nuLSU and 136 new for mtSSU. The results obtained from this work help to explain the
distribution of genera and species belonging to Gomphillaceae, contributing to the systematic
evolutionary knowledge within the group. 13 new genera phylogenetically established for the
family (Adelphomyces Xavier-Leite, M. Cáceres & Lücking, gen. nov., Aptrootidea XavierLeite, M. Cáceres & Lücking, gen. nov., Aulaxinella Xavier-Leite, M. Cáceres & Lücking,
gen. nov., Batistomyces Xavier-Leite, M. Cáceres & Lücking, gen. nov., Bezerroplaca XavierLeite, M. Cáceres & Lücking, gen. nov., Caleniella Xavier-Leite, M. Cáceres & Lücking, gen.
nov., Monocalenia Xavier-Leite, M. Cáceres & Lücking, gen. nov., Pseudocalenia XavierLeite, M. Cáceres & Lücking, gen. nov., Roselviria Xavier-Leite, M. Cáceres & Lücking, gen.
nov., Serusiauxiella Xavier-Leite, M. Cáceres & Lücking, gen. nov., Sipmanidea XavierLeite, M. Cáceres & Lücking, gen. nov., Verruciplaca Xavier-Leite, M. Cáceres & Lücking,
gen. nov., and Vezdamyces Xavier-Leite, M. Cáceres & Lücking, gen. nov..), four newly
reinstated genera (Microxyphiomyces Bat., Valle & Peres, Psathyromyces Bat. & Peres,
Spinomyces Bat. & Peres ex Xavier-Leite, M. Cáceres & Lücking, gen. nov., and
Sporocybomyces H. Maia), and 53 new combinations are introduced for species included in
the new and re-established genera. In addition, the analyzes confirmed polyphyletic groups,
and the previously distinguished and well supported genera. Finally, some small genera have
not yet been molecularly sampled. |
