Fruiting material of Chenia lorentzii (Bryophyta, Pottiaceae) found in Argentina and an evaluation of the sporophyte taxonomic value in the genus Chenia.

In the present contribution, the sporophyte of Chenia lorentzii is described in detail and microphotographs are provided. In addition, the role of sporophytic characters is discussed in a phylogenetic context. To accomplish this task, first, a phylogenetic analysis of a reduced dataset of Pottiaceae...

Character reconstruction morphology taxonomy. Morfología reconstrucción de caracteres taxonomía In the present contribution, the sporophyte of Chenia lorentzii is described in detail and microphotographs are provided. In addition, the role of sporophytic characters is discussed in a phylogenetic context. To accomplish this task, first, a phylogenetic analysis of a reduced dataset of Pottiaceae genera was carried out by using molecular data (nad5, rps4, 26S) and combined data (morphology and molecular markers). Then, gametophytic and sporophytic characters were mapped onto the molecular tree and their fit to the phylogeny was assessed on the basis of their extra steps and the number of diagnosed nodes. Results suggest that sporophytic characters should be treated with caution when nomenclatural generic changes are proposed. Material fructificado de Chenia lorentzii (Bryophyta, Pottiaceae) hallado en Argentina y una evaluación del valor taxonómico del esporofito en el género Chenia. En la presente contribución, el esporofito de Chenia lorentzii es descrito en detalle y se proveen fotomicrografías. Además, el rol de los caracteres esporofíticos es discutido en un contexto filogenético. Para ello, primero, se lleva a cabo un análisis filogenético de un dataset reducido de géneros de Pottiaceae empleando marcadores moleculares (nad5, rps4, 26S) y datos combinados (morfología y marcadores moleculares). Luego, los caracteres esporofíticos y gametofíticos son mapeados en el árbol de moléculas y su ajuste a la filogenia es medida en base a su número de pasos extras y el número de nodos diagnosticados. Los resultados sugieren que los caracteres esporofíticos deben ser evaluados con precaución al momento de proponer cambios nomenclaturales a nivel genérico.
