The genus Hygroaster belongs to family Hygrophoraceae Lotsy and is a sister genus of Hygrocybe Kumm, based on phylogenetic analysis of the three genes ITS (ITS 1-2 and 5.8S), LSU (25S) and SSU (18S) (Lodge et al. 2014).

The genus Hygroaster (Hygrophoraceae, Hygrophorineae) is a small genus with a tropical distribution. Based on morphological and phylogenetic analysis, two new species, H. madagascarensis and H. andasibensis, are described from Madagascar. They are the first species of this genus described from Africa. To stabilize the nomenclature, the type specimens of H. nodulisporus, the type species of the genus, and H. fucatus were studied. The initial combination of the name Hygrophorus nodulisporus in the genus Hygroaster was invalid and is thus validated here. In addition, our study revealed that H. fucatus belongs to the genus Asproinocybe in suborder Tricholomatineae, whose representatives also have nodulose basidiospores. A new combination A. fucata is proposed.

From the 1966 species of Agaricales sensu lato known from Argentina -d, 2013a-b, 2014, only 174 were found in the Argentinean Atlantic forest (Ramirez et al. 2012) and many of these species have been recently described (Lechner et al. 2005, Lechner et al. 2006, Uarth & Albertó 2009 or cited (Lechner et al. 2006, Niveiro et al. 2010, 2011.

Hemimycena longipleurocystidiata, a fungal species collected in the rgentinean Atlantic forest, is proposed as new. It is characterized by its whitish and large basidiomata with large pleuro- and cheilocystidia. The species is here described and illustrated and a key is provided to the Hemimycena species known from Argentina.

HISTORIAS DEL CENTRO DE INVESTIGACIONES ECOLÓGICAS SUBTROPICALES (CIES). EL VALOR DE LAS ESTACIONES BIOLÓGICAS. Andrés J. Bosso & Guillermo E. Gil (Organizadores)
Esta Estación Biológica dependiente de la Administración de Parques Nacionales (Argentina), está ubicada en el Parque Nacional Iguazú, provincia de Misiones, corazón del último gran remanente del bosque atlántico. Los organizadores pensaron esta obra para valorar el trabajo de cientos de personas que han pasado por su laboratorio y por las habitaciones de la primera Estación Biológica del sistema de Parques Nacionales de ese país. Los autores de los relatos son biólogos, naturalistas e investigadores, que nos cuentan de manera coloquial algunas de sus experiencias en este lugar tan singular, cargado de misticismo verde. Comienza con una recopilación de los datos de las estaciones biológicas de campo actuales en Argentina, una valoración del CIES por su rol como impulsor de la investigación y el conocimiento para la conservación y una retrospectiva histórica de esta Estación Biológica. Siguen 12 relatos de distintos autores, protagonistas de historias que se desarrollaron en torno al CIES. Todos estos capítulos poseen un listado bibliográfico producto de cada proyecto y 31 fotografías que ilustran elementos, momentos y personas mencionadas en el texto. Finalmente, como un testimonio del aporte de este Centro a la Biología, se enumeran las especies nuevas para la ciencia y para Argentina con material o registros del PN Iguazú, todas con sus correspondientes citas bibliográficas. Este libro electrónico consta de 97 páginas.
The kingdom Fungi is highly diverse and ecologically important for the maintenance of life in all ecosystems. However, the real diversity of these organisms is yet to be accessed. Hygrocybe s.l. is a group of agaricoid macrofungi in the Hygrophoraceae family that has vivid colours and thick, waxy lamellae. The group just went through a revision and many taxa of Hygrocybe were segregated. There are no specific works done with this group in Brazil and many herbaria specimens are lacking specific identifications. The Atlantic Rainforest is considered a biodiversity hotspot and accessing macrofungi species that occur in this phytogeographic domain is highly important to better understand and preserve its diversity. In this present study 28 specimens were collected and 4 herbaria material were analysed. The identified specimens were distributed in 14 taxa in 4 genera of Hygrophoraceae. Eight are possible new to science and are here described and discussed. A species list of Hygrocybe species from Brazil was provided as well as an identification key for the Brazilian Hygrocybe s.l. This work has contributed to increase the knowledge, distribution and diversity of Hygrocybe s.l. in the Atlantic Rainforest and in Brazil.
A new taxon of Hygroaster is proposed as H, cleefii. The collections representing this species were found in tropical lowland forests in the Departments of Caqueta and Chocó and on the Gorgona Islands of Colombia. The small size, the dark color of the basidiocarps and the translucent pileus surface are the macroscopic features that characterize this species. Hygroaster cleefii has smaller spores with longer spines than the other darkly pigmented species, H. nodulisporus. The presence of clamp connections differentiates H. cleefii, from the neotropical species of the genus.
ABSTRACT— A species checklist of 86 genera and 709 species belonging to the families Tricholomataceae and Polyporaceae occurring in Argentina, and including all the species previously published up to year 2011 is presented.
A checklist of species belonging to families Amanitaceae, Pluteaceae, and Hygrophoraceae was made for Argentina. The list includes all species published till year 2011. Eleven genera and 150 species were recorded. The family Pluteaceae is the most cited for the country with 93 species.
