The causative agents of black-grain eumycetoma mostly belong to the orders <jats:italic>Sordariales<\/jats:italic> and <jats:italic>Pleosporales<\/jats:italic>. The aim of the present\n study was to clarify the phylogeny and taxonomy of pleosporalean agents, viz. <jats:italic>Madurella grisea<\/jats:italic>, <jats:italic>Medicopsis romeroi<\/jats:italic> (syn.: <jats:italic>Pyrenochaeta romeroi<\/jats:italic>), <jats:italic>Nigrograna mackinnonii<\/jats:italic> (syn. <jats:italic>Pyrenochaeta mackinnonii<\/jats:italic>), <jats:italic>Leptosphaeria senegalensis<\/jats:italic>, <jats:italic>L. tompkinsii<\/jats:italic>,\n and <jats:italic>Pseudochaetosphaeronema larense<\/jats:italic>. A phylogenetic analysis based on five loci was performed: the Internal Transcribed Spacer (ITS), large (LSU) and small (SSU) subunit ribosomal RNA, the second largest RNA polymerase subunit (<jats:italic>RPB2<\/jats:italic>), and translation elongation factor 1-alpha\n (<jats:italic>TEF1<\/jats:italic>) gene. In addition, the morphological and physiological characteristics were determined. Three species were well-resolved at the family and genus level. <jats:italic>Madurella grisea<\/jats:italic>, <jats:italic>L. senegalensis<\/jats:italic>, and <jats:italic>L. tompkinsii<\/jats:italic> were found to belong to the family <jats:italic>Trematospheriaceae<\/jats:italic>\n and are reclassified as <jats:italic>Trematosphaeria grisea<\/jats:italic> comb. nov., <jats:italic>Falciformispora senegalensis<\/jats:italic> comb. nov., and <jats:italic>F. tompkinsii<\/jats:italic> comb. nov. <jats:italic>Medicopsis romeroi<\/jats:italic> and <jats:italic>Pseudochaetosphaeronema larense<\/jats:italic> were phylogenetically distant and both names are accepted. The genus <jats:italic>Nigrograna<\/jats:italic>\n is reduced to synonymy of <jats:italic>Biatriospora<\/jats:italic> and therefore <jats:italic>N. mackinnonii<\/jats:italic> is reclassified as <jats:italic>B. mackinnonii<\/jats:italic> comb. nov. Mycetoma agents in <jats:italic>Pleosporales<\/jats:italic> were phylogenetically quite diverse despite their morphological similarity in the formation of pycnidia, except for the\n ascosporulating genus <jats:italic>Falciformispora<\/jats:italic> (formerly in <jats:italic>Leptosphaeria<\/jats:italic>). Most of the species diagnosed from human mycetoma were found to be related to waterborne or marine fungi, suggesting an association of the virulence factors with oligotrophism or halotolerance.<\/jats:p>","DOI":"10.3767\/003158514x684744","type":"journal-article","created":{"date-parts":[[2014,9,17]],"date-time":"2014-09-17T04:34:32Z","timestamp":1410928472000},"page":"141-154","source":"Crossref","is-referenced-by-count":115,"title":["Revision of agents of black-grain eumycetoma in the order <i>Pleosporales<\/i>"],"prefix":"10.3114","volume":"33","author":[{"given":"S.A.","family":"Ahmed","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.W.J.","family":"van de Sande","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.A.","family":"Stevens","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Fahal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.D.","family":"van Diepeningen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.B.J.","family":"Menken","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.S.","family":"de Hoog","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1645","reference":[{"key":"R153_476_788","doi-asserted-by":"crossref","first-page":"25","DOI":"10.1016\/S0953-7562(09)80992-1","volume":"96","journal-title":"Mycological Research","ISSN":"https:\/\/id.crossref.org\/issn\/0953-7562","issn-type":"print"},{"key":"R153_495_692","first-page":"988994","volume":"50","journal-title":"Journal of Clinical Microbiology","ISSN":"https:\/\/id.crossref.org\/issn\/0095-1137","issn-type":"print"},{"key":"R153_359_606","first-page":"121130","volume":"47","journal-title":"Mycoses","ISSN":"https:\/\/id.crossref.org\/issn\/0933-7407","issn-type":"print"},{"key":"R153_468_568","first-page":"9598","volume":"41","journal-title":"Nucleic Acids Symposium Series","ISSN":"https:\/\/id.crossref.org\/issn\/0261-3166","issn-type":"print"},{"key":"R153_404_549","first-page":"154201","volume":"2012","journal-title":"pathology.","ISSN":"https:\/\/id.crossref.org\/issn\/0031-3025","issn-type":"print"},{"key":"R153_454_520","doi-asserted-by":"crossref","first-page":"1","DOI":"10.3114\/sim0004","volume":"75","journal-title":"Studies in Mycology","ISSN":"https:\/\/id.crossref.org\/issn\/0166-0616","issn-type":"print"},{"key":"R153_361_501","first-page":"10661081","volume":"102","journal-title":"Mycologia","ISSN":"https:\/\/id.crossref.org\/issn\/0027-5514","issn-type":"print"},{"key":"R153_437_463","first-page":"7591","volume":"42","journal-title":"American Journal of Clinical Patho- logy","ISSN":"https:\/\/id.crossref.org\/issn\/0002-9173","issn-type":"print"},{"key":"R153_519_434","first-page":"589592","volume":"84","journal-title":"Mycologia","ISSN":"https:\/\/id.crossref.org\/issn\/0027-5514","issn-type":"print"},{"key":"R153_409_377","first-page":"4666","volume":"32","journal-title":"sudan Medical Journal","ISSN":"https:\/\/id.crossref.org\/issn\/0491-4481","issn-type":"print"},{"key":"R153_351_367","first-page":"406411","volume":"58","journal-title":"Mycologia","ISSN":"https:\/\/id.crossref.org\/issn\/0027-5514","issn-type":"print"},{"key":"R153_428_339","first-page":"35173523","volume":"44","journal-title":"Journal of Clinical Microbiology","ISSN":"https:\/\/id.crossref.org\/issn\/0095-1137","issn-type":"print"},{"key":"R153_421_310","first-page":"121123","volume":"21","journal-title":"the journal of tropical medicine and hygiene.","ISSN":"https:\/\/id.crossref.org\/issn\/0022-5304","issn-type":"print"},{"key":"R153_339_300","first-page":"197201","volume":"104","journal-title":"Archives of Dermatology","ISSN":"https:\/\/id.crossref.org\/issn\/0003-987X","issn-type":"print"},{"key":"R153_428_272","first-page":"997","volume":"58","journal-title":"Comptes Rendus hebdomadaires des seances de lAcademie des Sciences","ISSN":"https:\/\/id.crossref.org\/issn\/0001-4036","issn-type":"print"},{"key":"R153_315_253","doi-asserted-by":"crossref","first-page":"689","DOI":"10.1093\/mmy\/myu035","volume":"52","journal-title":"Medical Mycology","ISSN":"https:\/\/id.crossref.org\/issn\/1369-3786","issn-type":"print"},{"key":"R154_526_466","doi-asserted-by":"crossref","first-page":"85","DOI":"10.3114\/sim.2009.64.04","volume":"64","journal-title":"Studies in Mycology","ISSN":"https:\/\/id.crossref.org\/issn\/0166-0616","issn-type":"print"},{"key":"R154_456_437","first-page":"47","volume":"33","journal-title":"FUNGAL DIVERSITY","ISSN":"https:\/\/id.crossref.org\/issn\/1560-2745","issn-type":"print"},{"key":"R154_453_418","first-page":"1221","volume":"53","journal-title":"Pleosporales.
