Timothy J. Baroni, Biological Sciences Department, co-authored a peer-reviewed paper recently published in the Argentinian journal Kurtziana. The article, “New Species and Records of Pouzarella (Agaricomyetes, Entolomataceae) from Northern Argentina/Nuevas especies y nuevas citas de Pouzarella (Agaricomyetes, Entolomataceae) del Norte Argentino,” was one of 13 invited scientific publications in an edited edition on mycological topics in South America. The publication was designed to honor Leif Ryvarden, University of Oslo, Norway, for his contributions to mycological research in South America over the past 40 years. The three co-authors, all from Argentina, included Edgardo Alberta of the Instituto de Investigaciones Biotecnológicas, Buenos Aires; Nicolas Niveiro, Instituto de BotÃ¡nica del Nordeste, Sargento Cabral; and Bernardo Lechner, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires. Baroni and his colleagues’ paper on new species and rarely observed mushrooms of northern Argentina’s national parks and reserves came from a two-week expedition made last spring while Baroni was on sabbatical leave. Baroni had been invited as guest and collaborator to study the macrofungal diversity of several remote regions in the Yungas ecosystem of northern South America by Alberta.
