| dc.description.abstract | Species of tropical tar spot fungi (Phyllachorales, Ascomycota) are obligate biotrophic plant
parasitic fungi associated with living leaves of a wide range of families of host plants, mainly in
tropical and subtropical regions. In this study, samples of tropical tar spot fungi were collected
in forests in Costa Rica and Panamá. To identify taxa, we used morphology and information on
host plants and combined multigene phylogeny of four genes: the large subunit nuclear
ribosomal DNA (28S rDNA), the small subunit nuclear ribosomal DNA (18S rDNA), the complete
internal transcribed spacer region of ribosomal DNA (nuc rDNA ITS1-5.8S-ITS2; ITS), and the
translation elongation factor 1-α (tef1). Here we propose one new species in the genus
Camarotella and eight new species in Telimena with their morphological descriptions, illustrations,
and sequence data. The newly described species are Camarotella licaniae on Licania
arborea (Chrysobalanaceae) and in the genus Telimena: T. billiae on Billia rosea (Sapindaceae),
T. drymoniae on Drymonia multiflora (Gesneriaceae), T. hydrangeae on Hydrangea sp.
(Hydrangeaceae), T. miravallensis on Symplocos panamensis (Symplocaceae), T. protii on
Protium sp. (Burseraceae), T. rinoreae on Rinorea sp. (Violaceae), T. semialarii on Semialarium
mexicanum (Celastraceae), and T. triseptata on Tapirira mexicana (Anacardiaceae). The new name
Telimena nitens on Schlegelia brachyanta (Schlegeliaceae) is presented and 10 species of
Phyllachora are transferred to Telimena, leading to the new combinations T. canarii, T. galavisii,
T. insueta, T. ruelliae, T. scutiformis, T. serjaniicola, T. spicatae, T. subrepens, T. symploci, and T.
symplocicola. Additionally, revisions of tar spot fungi on host families Burseraceae, Sapindaceae,
and Symplocaceae are provided, and four new synonyms are proposed. | |
