ABSTRACT<\/strong><\/h4>\n

The term polypore is used to denote the fungi belonging to Basidiomycota that present a tubular hymenophore. These fungi form a polyphyletic group and are included in several orders of Agaricomycetes, Polyporales being the largest of them. Within this order, the genera <\/span>Antrodiella<\/span><\/i>, <\/span>Flaviporus<\/span><\/i>, <\/span>Junghuhnia<\/span><\/i> and <\/span>Tyromyces<\/span><\/i> are characterized by causing white rot in dead wood, by the presence of mono-dimitic hyphal system with clamped generative hyphae and hyaline and small basidiospores. Molecular studies have shown that these genera are highly polyphyletic, but so far few Neotropical species have been included in phylogenetic analyzes. In addition, little or nothing is known about their biological characteristics, such as mating system and nuclear behavior, which may be important tools in the separation of morphologically similar genera. This study aims to contribute in this context, increasing the knowledge on the diversity and distribution of the four genera in Brazil, providing morphological, molecular and biological data for a better understanding of their systematics. Specimens were collected in the states of RS, SC, PR and SP and all materials were analyzed morphologically. Collections of type specimens, as well as other herbarium materials, were studied for comparison and confirmation of identifications. Polysporic and monosporic cultures were obtained and used for nuclear staining and compatibility tests. For the molecular analysis, sequences obtained of the ITS, LSU, <\/span>tef<\/span><\/i>1-\u03b1 and <\/span>rbp<\/span><\/i>2 regions were used to build phylogenetic trees by applying Bayesian Inference and Maximum Likelihood. Molecular data obtained confirmed the high polyphyletism of the group, with species distributed in several genera in the phlebioid and residual polyporoid clades. The morphological and phylogenetic analysis revealed the occurrence of 24 species of the studied group, six of them being new to science and other three requiring further sampling to confirm if they represent new taxa. Two new genera have been confirmed and are proposed and at least seven new combinations are needed to transfer species to the appropriate genera. Furthermore, biological data from 12 species were obtained, representing a significant increase in the knowledge on the group and, allied with morphological characteristics, an important tool for the delimitation of genera.<\/span>

RESUMO<\/strong><\/h4>\n

O termo pol\u00edporo \u00e9 utilizado para denominar os fungos do filo Basidiomycota que apresentam himen\u00f3foro tubular. Estes fungos formam um grupo polifil\u00e9tico, estando inclu\u00eddos em diversas ordens da classe Agaricomycetes, sendo Polyporales a maior delas. Dentro desta ordem, os g\u00eaneros <\/span>Antrodiella<\/span><\/i>, <\/span>Flaviporus<\/span><\/i>, <\/span>Junghuhnia<\/span><\/i> e <\/span>Tyromyces<\/span><\/i> se caracterizam por serem causadores de podrid\u00e3o branca na madeira, pela presen\u00e7a de sistema hifal mono a dim\u00edtico com hifas generativas fibuladas e pelos basidi\u00f3sporos hialinos e pequenos. Estudos moleculares demonstraram o alto grau de polifiletismo desses g\u00eaneros, no entanto at\u00e9 o momento poucas esp\u00e9cies neotropicais foram inclu\u00eddas em an\u00e1lises filogen\u00e9ticas. Al\u00e9m disso, pouco ou nada se conhece a respeito de suas caracter\u00edsticas biol\u00f3gicas, tal como polaridade sexual e comportamento nuclear, que podem ser importantes ferramentas na separa\u00e7\u00e3o de g\u00eaneros morfologicamente semelhantes. Este estudo teve como objetivo auxiliar neste quadro, incrementando o conhecimento da diversidade e distribui\u00e7\u00e3o dos quatro g\u00eaneros no Brasil, fornecendo dados morfol\u00f3gicos, moleculares e biol\u00f3gicos para uma melhor compreens\u00e3o de sua sistem\u00e1tica. As coletas foram realizadas nos estados do RS, SC, PR e SP e todos os materiais foram analisados morfologicamente. Cole\u00e7\u00f5es de materiais tipo, bem como outros esp\u00e9cimes de herb\u00e1rios, foram estudadas para compara\u00e7\u00e3o e confirma\u00e7\u00e3o das identifica\u00e7\u00f5es. Culturas polisp\u00f3ricas e mon\u00f3sporicas foram obtidas e utilizadas para t\u00e9cnicas de colora\u00e7\u00e3o de n\u00facleo e testes de compatibilidade. Para as an\u00e1lises moleculares, sequencias obtidas das regi\u00f5es ITS, LSU, <\/span>tef<\/span><\/i>1-\u03b1 e <\/span>rbp<\/span><\/i>2 foram utilizadas para constru\u00e7\u00e3o de \u00e1rvores filogen\u00e9ticas aplicando infer\u00eancia Bayesiana e M\u00e1xima Verossimilhan\u00e7a. Os moleculares obtidos confirmam o alto polifiletismo do grupo, apresentando esp\u00e9cies distribu\u00eddas em diversos g\u00eaneros nos clados phlebioide e residual poliporoide. As an\u00e1lises morfol\u00f3gicas e filogen\u00e9ticas revelaram a ocorr\u00eancia de 24 esp\u00e9cies do grupo estudado, sendo que destas seis s\u00e3o novas para a ci\u00eancia e outras tr\u00eas necessitam de mais coletas para confirmar se representam novos t\u00e1xons. Dois novos g\u00eaneros foram confirmados e s\u00e3o propostos e pelo menos sete novas combina\u00e7\u00f5es s\u00e3o necess\u00e1rias para transferir esp\u00e9cies para os g\u00eaneros adequados. Al\u00e9m disso, foram obtidos dados biol\u00f3gicos de 12 esp\u00e9cies, representando um significativo incremento no conhecimento do grupo e, aliados \u00e0s caracter\u00edsticas morfol\u00f3gicas, uma ferramenta importante para a delimita\u00e7\u00e3o dos g\u00eaneros.<\/span>
