Study of the rediscovered holotype of Plicaria tiliacea confirms that this species belongs
to the genus Peziza. Type studies show that it is similar to but different from Peziza
prosthetica and Peziza obtusapiculata. Peziza vacekii, nom. nov., is proposed to replace
Peziza tiliacea (Vacek) J. Moravec 1985, a later homonym of P. tiliacea Fr.: Fr. 18...

This is the first in a series of group-by-group treatments of the taxonomy and nomenclature of the molluscs of Singapore based on a review of the literature and examination of geographically relevant material. The family Angariidae is treated. Angaria delphinus is the only representative of the family to be found in Singapore. It was first recorded...
We carried out a taxonomic study of the leptosporangiate fern family Gleicheniaceae (Polypodiopsida) in Brazil out and accepted 17 species distributed in three genera. Taxonomic descriptions to the whole family, genera and species are provided, as well as keys to the genera and species, synonymies, maps, illustrations, and notes. We also provide no...

... Van Vooren & Moyne (2004) describe la primera cita para Francia de P. prosthetica a partir de una revisión de material de herbario identificado previamente como P. apiculata y señala que, aunque son especies parecidas, y tal y como indicaba Moravec (1985a), la especia más próxima es P. obtusapiculata, diferenciándose por la longitud y ornamentación esporal. Más recientemente Cacialli et al. (2012), al darle el nuevo nombre de Peziza vacekii Cacialli, Lantieri & Medardi a Plicaria tiliacea Vacek, estudian los holotipos de P. tiliacea y P. obtusapiculata y el isotipo de P. prosthetica, llegando a la conclusión de que son tres especies diferentes, tanto por la composición de los excípulos como por la ornamentación y apículos esporales. En la tabla 3 realizamos una comparativa de las descripciones originales de P. obtusapiculata y P. prosthetica, las descripciones de P. vacekii, P. prosthetica y P. obtusapiculata de Cacialli et al. (2012) y nuestra recolecta. ...
In order to contribute to the knowledge of the fungal diversity in the Parque Nacional de Ordesa y Monte Perdido, a taxonomic revision of the species collected throught 2014 has been made, classified in three levels: a) new or very special interest species, b) interesting or uncommon species, c) other species. Given the breadth of the territory that has been studied, prospecting areas have been limited to the bassins of the Ara, Arazas, Bellós, Yaga and Cinca rivers.
311 taxa were identified, corresponding 240 to Phyllum Basidiomycota, 61 to Ascomycota and 10 to Myxomycota; the most representative orders are Agaricales, Russulales, Pezizales, Polyporales, Boletales and Helotiales. Among the identified species, have been found 9 between the proposals for the catalog of protected species of the Iberian Peninsula and/ or Aragón.
In this paper a first contribution to the catalog is showed, first as a list of all identified taxa and then, a taxonomic description with its macro and microscopic iconography for 16 of them, corresponding with interesting or uncommon species.
