Diversity and Altitudinal Distribution of Understorey Corticolous Lichens in a Tropical Montane Forest in Kenya (East Africa).
Kirika, Paul M.; Ndiritu, George G.; Mugambi, George; Newton, Leonard E.; Lumbsch, Thorsten (ResearchGate, 2017)Lichens constitute an important component of tropical forest biodiversity. This study inventoried corticolous lichens and examined their variation in various forest types with varying climatic conditions in Mt. Kenya, ... -
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 ... -
Isolation of Haloalkaliphilic Fungi from Lake Magadi in Kenya
Orwa, Philemon; Mugambi, George; Wekesa, Vitalis; Mwirichia, Romano (Heliyon, 2020)In this study we explored the cultivable fungal diversity in Lake Magadi and their secondary metabolite production. Isolation was done on alkaline media (Potato dextrose agar, Malt extract agar, Oatmeal agar and Sabouraud ... -

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 ... -
A molecular phylogenetic reappraisal of the Hysteriaceae, Mytilinidiaceae and Gloniaceae (Pleosporomycetidae, Dothideomycetes) with keys to world species.
Boehm, E W A; Mugambi, George; Miller, A N.; Huhndorf, S M; Marincowitz, S; Spatafora, J W; Schoch, C L (PubMed, 2009)A reappraisal of the phylogenetic integrity of bitunicate ascomycete fungi belonging to or previously affiliated with the Hysteriaceae, Mytilinidiaceae, Gloniaceae and Patellariaceae is presented, based on an analysis of ... -
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 ... -
Multigene phylogeny of the Coronophorales (ascomycota): morphology and new species in the order.
Mugambi, George; Huhndorf, S.M. (PubMed, 2009)The phylogenetic relationships within Coronophorales have been debated because of uncertainty over the taxonomic usefulness of characterisitics such as quellkörper, number of ascospore appendages, presence of subiculum and ... -
New Records of Lichen-forming Fungi from Kenya
Kirika, Paul; Mugambi, George; Lücking, Robert; Lumbsch, H. Thorsten (Journal of East African Natural History, 2012) -
A new species of Melanochaeta from Kenya
Mugambi, George; Huhndorf, Sabine M. (Verlag Ferdinand Berger & Söhne Ges.m.b.H., 2008)Melanochaeta taitensis is described as a new species from Kenya. It is distinguished from the other known species of Melanochaeta by having large, 3-septate, strongly curved ascospores. Phylogenetic analyses of nuclear 28S ... -
Parallel evolution of hysterothecial ascomata in ascolocularous fungi (Ascomycota, Fungi).
Mugambi, George; Huhndorf, S. (The Natural History Museum, 2009-12-01)Ascoma morphologies have traditionally been used to classify filamentous ascomycete fungi. Phylogenies generated using DNA sequence data have since shown most of the previously identified groups not to be monophyletic. The ... -
Phylogenetic studies uncover a predominantly African lineage in a widely distributed lichen-forming fungal species
Kirika, Paul M.; Divakar, Pradeep K.; Crespo, Ana; Mugambi, George; Orock, Elizabeth A.; Leavit, Steven D.; Gatheri, Grace W.; Lumbsch, H. Thorsten (MycoKeys, 2016)A number of lichen-forming fungal species are widely distributed. Here, we investigate biogeographic patterns in a widely distributed isidiate taxon –Parmelinella wallichiana – using molecular sequence data. Our results ... -
Two new genera in Magnaporthaceae, a new addition to Ceratosphaeria, and two new species of Lentomitella
Huhndorf, Sabine M; Greif, Matthew; Mugambi, George; Miller, Andrew N (2008)Ceratosphaerella is described as a new genus for C. castillensis and C. rhizomorpha. The genus is related to Ophioceras but distinguished by ascomata with a basal stroma and shorter, fusiform ascospores. Muraeriata is ... -
