    • The genus Relicinopsis is nested within Relicina (Parmeliaceae, Ascomycota). 

      Kirika, Paul M.; Divakar, Pradeep K; Leavitt, Steven D.; Buaruang, Kawinnat; Crespo, Ana; Mugambi, George; Gatheri, Grace W.; Lumbsch, Thorsten (British Lichen Society, 2017)
      Macro-morphological features traditionally used to segregate genera in Parmeliaceae have been shown to be highly plastic, placing limits on their taxonomic value. Here we aim to elucidate the evolutionary relationships of ...

    • Molecular data show that Hypotrachyna sorocheila (Parmeliaceae) is not monophyletic 

      Kirika, Paul M.; Divakar, Pradeep K.; Crespo, Ana; Gatheri, Grace W.; Mugambi, George; Leavitt, Steven D.; Moncada, Bibiana; Lumbsch, H. Thorsten (The American Bryological and Lichenological Society, Inc, 2016)
      Lichens that reproduce by means of vegetative propagules (soredia or isidia) are generally thought to have broad geographic distributions. However, recent studies have shown that some asexually reproducing lichens with ...

    • Molecular phylogenetic studies unmask overlooked diversity in the tropical lichenized fungal genus Bulbothrix s.l. (Parmeliaceae, Ascomycota) 

      Kirika, Paul M.; Divakar, Pradeep K.; Buaruang, Kawinnat; Leavitt, Steven D.; Crespo, Ana; Gatheri, Grace W.; Mugambi, George; Benatti, Michel N.; Lumbsch, H. Thorsten (Botanical Journal of the Linnean Society, 2017)
      Species boundaries in lichen-forming fungi occurring in extra-tropical regions are relatively well studied in comparison with those in species distributed in tropical regions. Here, we aim to re-examine species boundaries ...

    • The monotypic genus Bulborrhizina belongs to Bulbothrix sensu lato (Parmeliaceae, Ascomycota) 

      Kirika, Paul M.; Leavitt, Steven D.; Divakar, Pradeep K.; Crespo, Ana; Gatheri, Grace W.; Mugambi, George; Lumbsch, H. Thorsten (The American Bryological and Lichenological Society, Inc., 2015)
      The phylogenetic position of the monotypic genus Bulborrhizina is studied using molecular data from three loci (mtSSU, nuLSU and ITS) aligned with sequences from 95 other samples of parmelioid lichens. Bulborrhizina africana ...
