Geastrum chamelense (Geastraceae, Agaricomycetes), a new species with setose endoperidium from the tropical dry forest in Jalisco, Mexico
Background and Aims: Geastrum is characterized by stelliform basidiomata, exoperidium with three layers, sessile or stalked endoperidium, and sulcate, plicate, folded or fibrillose peristome, distinctly or indistinctly delimited, sometimes with mycosclereids. The objective of this study is to descri...

| description | Background and Aims: Geastrum is characterized by stelliform basidiomata, exoperidium with three layers, sessile or stalked endoperidium, and sulcate, plicate, folded or fibrillose peristome, distinctly or indistinctly delimited, sometimes with mycosclereids. The objective of this study is to describe and illustrate Geastrum chamelense with morphological, ecological and molecular data as a new species from the Chamela Biological Station, Jalisco, Mexico.
Methods: Basidiomata collections with different degrees of maturity gathered in 2010 and 2011 from tropical dry forest at the Chamela Biological Station in Jalisco state are described macro- and microscopically. The type material is deposited in the fungal collections of the herbaria ENCB and MEXU. The extraction of DNA, as well as the phylogenetic analyses of ITS, LSU, atp6 and rpb1 sequences, are based on the holotype.
Key results: Geastrum chamelense is distinguished by its greyish brown basidiomata, pseudofornicate, fleshy exoperidium, not hygroscopic, sessile endoperidium, subglobose to depressed with peristome plicate, not delimited, and setae present. The latter character is shared with Geastrum setiferum from Brazil, but that species has shorter and wider setae (95-215 × 20-47 µm) than G. chamelense (102-330 × 10.2-15.3 µm). From a phylogenetic perspective, G. chamelense is sister to G. hieronymi and G. cf. calceum, while G. setiferum is not related, as it appears in a separate clade.
Conclusions: Geastrum chamelense is recognized as a new species based on morphological, ecological and molecular data. |

Antecedentes y Objetivos: Geastrum se caracteriza por presentar basidiomas esteliformes, exoperidio con tres capas, endoperidio sésil o estipitado, peristoma sulcado, plegado, doblado o fibriloso, distintiva o indistintivamente delimitado, algunas veces con micoesclereidas. El objetivo de este estudio es describir e ilustrar a Geastrum chamelense con datos morfológicos, ecológicos y moleculares como una especie nueva de la Estación de Biología Chamela, Jalisco, México. Métodos: Las colecciones de basidiomas con diferentes grados de madurez recolectados en 2010 y 2011 del bosque tropical caducifolio de la Estación de Biología Chamela en el estado de Jalisco se describen macro y micromorfológicamente. El material tipo está depositado en las colecciones micológicas de los herbarios ENCB y MEXU. La extracción de ADN, así como los análisis filogeneticos de secuencias de ITS, LSU, atp6 y rpb1, se basan en el holotipo. Resultados clave: Geastrum chamelense se distingue por sus basidiomas pardo grisáceos, exoperidio pseudofornicado, carnoso, no higroscópico y endoperidio sésil, subgloboso a deprimido con peristoma plegado, no delimitado, y presencia de setas. Este último carácter se comparte con Geastrum setiferum de Brasil, pero ésta tiene setas más cortas y anchas (95-215 × 20-47 µm) que G. chamelense (102-330 × 10.2-15.3 µm). Desde una perspectiva filogenética, G. chamelense tiene como grupo hermano a G. hieronymi y G. cf. calceum, mientras que G. setiferum no está relacionado porque aparece en un clado separado. Conclusiones: Geastrum chamelense es reconocida como una especie nueva basada en datos morfológicos, ecológicos y moleculares.
