Resumo: Porotrichum squarrosum has never been reported from Brazil and it is a new record. While revising herbarium specimens we found a specimen named Pireella squarrosa (currently  Porotrichum), identified by Massimo Mastracci. We have compared this specimen with records from literature and several hundreds of specimens and found that among specimens previously determined as P. substriatum several belong to P. squarrosum. These taxa are a quite common in Brazil ranging from Amazon, Atlantic Forest to Cerrado phytogeographical domains at elevations from near sea level to about 600 m. These taxa are fast differentiated by the squarrose leaves, spur costa at back and absence of stem central strand in P. squarrosum against to complanate leaves, without spurowed costa at back and presence of central strand in P. substriatum.

Durante a revisão de espécimes de herbário, o nome Pireella squarrosa (atualmente Porotrichum), identificado por Massimo Mastracci foi encontrado em algumas plantas. Após a comparação com literatura e centenas de espécimens de herbário, verificamos que P. squarrosum é uma espécie comum no Brasil, ocorrendo desde o domínio fitogeográfico da Amazônia até a Mata Atlântica e Cerrado em elevações desde o nível do mar até próximo 600 m. Esses táxons são rapidamente diferenciados pelos filídios esquarrosos, costa com esporão dorsal e ausência de banda central de estereides no caulídio em P. squarrosum em contraposição a filídios complanados, sem costa esporada dorsalmente e presença de banda central de estereides no caulídio em P. substriatum.SciELO PreprintsSciELO PreprintsSciELO Preprints2021-05-20info:eu-repo/semantics/preprintinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://preprints.scielo.org/index.php/scielo/preprint/view/234510.1590/2236-8906-107/2020enghttps://preprints.scielo.org/index.php/scielo/article/view/2345/3966Copyright (c) 2021 Denilson Fernandes Peralta, Alfons Schäfer-Verwimphttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPeralta, Denilson Fernandes Schäfer-Verwimp, Alfons reponame:SciELO Preprintsinstname:SciELOinstacron:SCI2021-05-20T00:59:28Zoai:ops.preprints.scielo.org:preprint/2345Servidor de preprintshttps://preprints.scielo.org/index.php/scieloONGhttps://preprints.scielo.org/index.php/scielo/oaiscielo.submission@scielo.orgopendoar:2021-05-20T00:59:28SciELO Preprints - SciELOfalse
