Fernanda Karstedt, aluna de doutorado do Programa de P\u00f3s-Gradua\u00e7\u00e3o em Biodiversidade Vegetal e Meio Ambiente, defendeu no dia 28 de julho de 2014 a tese intitulada \u201cEntolomataceae<\/em> com basidi\u00f3sporos cuboides no brasil: revis\u00e3o taxon\u00f4mica e contribui\u00e7\u00e3o para a filogenia molecular\u201d.<\/p>\n A banca examinadora foi composta pela orientadora, Dra. Marina Capelari (Instituto de Bot\u00e2nica), e pelos avaliadores Dr. Denilson Fernandes Peralta (Instituto de Bot\u00e2nica), Dr. Marcelo Pinto Marcelli (Instituto de Bot\u00e2nica), Dra. Maria Alice de Neves (UFSC) e Dra. Val\u00e9ria Cassiano (USP).<\/p>\n Entolomataceae <\/em>species are characterized by spore shape, which may be bumpy, ridged, or angular with four to nine angles in profile. The generic classification is mainly based on the habit, as well as on the pileae surface. Consequently, the species with cuboidal basidiospores occur within different genera. The aim of this study was to elucidate the relationship of species with cuboidal basidiospores inside the Entolomataceae <\/em>phylogeny. The phylogenetic analyses supported that the studied species grouped into two clades weakly related to the Inocephalus- Cyanula clade. Therefore, based upon molecular and morphological evidence, two new genera are proposed herewith: Cuboeccilia <\/em>and Cubospora<\/em>. Cuboeccilia <\/em>is characterized by an omphalinoid habit and fusoid cystidia whereas Cubospora <\/em>is characterized by a mycenoid to tricholomatoid habit and clavate, rarely fusoid cheilocystidia. With the molecular and morphological analysis, a total of 28 species with cuboidal basidiospores were recorded for Brazil, with a new species of Cuboeccilia<\/em>, Cuboeccilia largentiana<\/em>, and 27 species of Cubospora<\/em>, of which 15 species are new to science, Cubospora amazonica<\/em>, C. arenicola<\/em>, azurea<\/em>, C. atlantica<\/em>, C. brasiliensis<\/em>, C. brunneolosquamulosa<\/em>, C. caelesta<\/em>, C. gatesiana, <\/em>luteobrunnea<\/em>, C. noordeloosiana<\/em>, C. membranacea<\/em>, C.\u00a0 eotropicalis<\/em>, C. papillata<\/em>, rufescens <\/em>and C. vinososquamulosa<\/em>; 12 species correspond to new combinations, two of them being new records for Brazil, C. acutopallida <\/em>and C. luteolamellata <\/em>and four being new records for the states from which they were sampled, C. caribaea<\/em>, C. cervina<\/em>, C. dragonospora <\/em>and C. lycopersica<\/em>. The morphological review of the collections has also ruled out the species Cubospora avilana <\/em>and actually puts to question the citation of C. kamerunensis<\/em>.<\/p>\n Key words:<\/strong> Agaricales, fungi, diversity, phylogeny, taxonomy.<\/p>\n As esp\u00e9cies de Entolomataceae <\/em>s\u00e3o caracterizadas pelos basidi\u00f3sporos rugoso- facetados, ou longitudinalmente sulcados ou angulados, variando de quatro a nove \u00e2ngulos em perfil. A classifica\u00e7\u00e3o da fam\u00edlia usualmente utiliza o tipo de h\u00e1bito e de superf\u00edcie pilear para agrupar os g\u00eaneros, e desse modo as esp\u00e9cies com basidi\u00f3sporos cuboides ocorrem em diferentes g\u00eaneros. O presente trabalho teve como objetivo elucidar a rela\u00e7\u00e3o filogen\u00e9tica das esp\u00e9cies com basidi\u00f3sporos cuboides. As an\u00e1lises filogen\u00e9ticas suportaram que as esp\u00e9cies com basidi\u00f3sporos cuboides est\u00e3o agrupadas em dois clados fracamente relacionados no clado Inocephalus-Cyanula e com base nas evid\u00eancias moleculares e morfol\u00f3gicas dois g\u00eaneros novos est\u00e3o sendo propostos, Cuboeccilia <\/em>e Cubospora<\/em>, diferindo por Cuboeccilia <\/em>ser caracterizada por ter h\u00e1bito onfalinoide e cist\u00eddios fusoides presentes e Cubospora <\/em>por ter h\u00e1bito variando de micenoide a tricolomatoide e queilocist\u00eddios frequentemente clavados. Como resultado, um total de 28 esp\u00e9cies com basidi\u00f3sporos cuboides foram aceitos para o Brasil, sendo uma esp\u00e9cie nova de Cuboeccilia, C. largentiana<\/em>, e 27 esp\u00e9cies de Cubospora<\/em>, das quais\u00a015 s\u00e3o esp\u00e9cies novas para a ci\u00eancia, Cubospora amazonica<\/em>, C. arenicola<\/em>, C. azurea<\/em>, atlantica<\/em>, C. brasiliensis<\/em>,\u00a0\u00a0 \u00a0C.\u00a0\u00a0 \u00a0brunneolosquamulosa<\/em>,\u00a0\u00a0 \u00a0C.\u00a0\u00a0 \u00a0caelesta<\/em>,\u00a0\u00a0 \u00a0C.\u00a0\u00a0 \u00a0gatesiana, <\/em>luteobrunnea<\/em>, C.\u00a0 oordeloosiana<\/em>,\u00a0 \u00a0C. membranacea<\/em>,\u00a0 \u00a0C.\u00a0 \u00a0neotropicalis<\/em>,\u00a0 \u00a0C. papillata<\/em>, rufescens <\/em>e C. vinososquamulosa<\/em>; 12 esp\u00e9cies correspondem \u00e0 combina\u00e7\u00f5es novas, das quais duas s\u00e3o ocorr\u00eancias novas para o Brasil, C. acutopallida <\/em>e C. luteolamellata <\/em>e quatro s\u00e3o amplia\u00e7\u00f5es na distribui\u00e7\u00e3o para os estados dos quais foram amostradas, C. caribaea<\/em>, C. cervina<\/em>, dragonospora <\/em>e C. lycopersica<\/em>.
