First record of Tulostoma exasperatum (Agaricaceae, Agaricales) in Mexico
Background and Aims: The genus Tulostoma groups species that are characterized by their angiocarpic basidiomes with a spore-sac possessing an apical mouth or ostiole and a well-defined stipe. Worldwide, 173 species are known, and 49 species have been cited in Mexico. One of the few species in the ge...

| description | Background and Aims: The genus Tulostoma groups species that are characterized by their angiocarpic basidiomes with a spore-sac possessing an apical mouth or ostiole and a well-defined stipe. Worldwide, 173 species are known, and 49 species have been cited in Mexico. One of the few species in the genus with lignicolous habit is T. exasperatum, which, in combination with its morphological traits, makes it a distinctive species. The aim of this work is to present T. exasperatum as a first record for Mexico.Methods: The material was collected in “Las Maravillas de Acahuato” ranch, Apatzingán municipality, Michoacán state, Mexico. The specimen was characterized macro and microscopically by in situ photographs, polarized light microscopy, light microscopy and scanning electron microscopy. Identification was carried out with specialized literature. Studied material is deposited in the macromycetes collection of the National Herbarium (MEXU) of the Biology Institute of Universidad Nacional Autónoma de México.Key results: Tulostoma exasperatum is recorded for the first time in Mexico, based on Mexican specimens. The species is distinguished by its exoperidium with reddish-brown conical to pyramidal verrucae that, when detached, leave lattice-like marks on the endoperidium, fimbriate ostiole, and winged reticulate basidiospores. In addition, its lignicous habit is characteristic, in soils rich in organic matter.Conclusions: Tulostoma exasperatum presents pantropical distribution. The morphology of the pigmented cells of the exoperidium warts is a poorly studied source of taxonomic information. The catalog of species of the genus Tulostoma in Mexico is raised to 50 species, and the number of gasteroid Agaricomycetes in Michoacán is raised to 38 species. |

Antecedentes y Objetivos: El género Tulostoma agrupa especies que se caracterizan por sus basidiomas angiocárpicos con un saco esporífero, poseyendo un ostiolo o boca apical y un estípite bien definido. A nivel mundial se conocen 173 especies y se han reportado 49 en México. Una de las pocas especies del género con hábito lignícola es T. exasperatum, que, en combinación con sus características morfológicas, la definen claramente. El objetivo de este trabajo es presentar a T. exasperatum como primer registro para México.Métodos: El material fue recolectado en el rancho “Las Maravillas de Acahuato”, municipio de Apatzingán, estado de Michoacán, México. El ejemplar fue caracterizado macro- y microscópicamente mediante fotografías in situ, microscopía polifocal, de luz y electrónica de barrido. La identificación se realizó mediante literatura especializada. El material estudiado se depositó en la colección de macromicetos del Herbario Nacional (MEXU) del Instituto de Biología de la Universidad Nacional Autónoma de México. Resultados clave: Se registra por primera vez a Tulostoma exasperatum basado en la descripción de descripción de especímenes mexicanos. La especie se distingue por su exoperidio con verrugas cónicas a piramidales de color marrón rojizo, que al desprenderse dejan marcas a manera de retícula en el endoperidio, ostiolo fimbriado y basidiosporas reticuladas aladas. Además es característico su hábito lignícola en suelos ricos en materia orgánical. Conclusiones: Tulostoma exasperatum presenta distribución pantropical. La morfología de las células de las verrugas del exoperidio son una fuente de información taxonómica poco estudiada. El catálogo de especies del género Tulostoma para México se eleva a 50 y el número de Agaricomycetes gasteroides en Michoacán a 38.
