The genus Pluteus (Pluteaceae, Agaricales) from the state of Paraná, Brazil

Taxonomy and phylogeny of Pluteus glaucotinctus sensu lato (Agaricales, Basidiomycota), a multicontinental species complex

“…Recently, Menolli et al (2014) reported the presence of cheilocystidia with incrusting parietal pigment at the apex in one Brazilian material (coll. ANc-4214) under the name of P. glaucotinctus.…”

Pluteus Fr. (Pluteaceae, Agaricales) in Paraguay: morphological studies and new records

“…They both have clamp connections in the trama, pileipellis and context as well as Magnus-type pleurocystidia (Singer 1956, Pegler 1983). However, P. fibulatus has globose basidiospores (Menolli et al 2015a) in contrast with the subglobose basidiospores described for P. spinulosus (Singer 1956). In addition, Magnustype pleurocystidia with lateral spinulose outgrowths towards the apex are described for P. spinulosus (Singer 1956, Pegler 1983, while P. fibulatus has Magnus-type and metuloid pleurocystidia (Menolli et al 2015a) with bifurcations that bear apical spinules as observed in the Paraguayan material ( Fig.…”

“…In South America, the genus Pluteus has been fairly well studied and recorded from Argentina (Singer 1952, 1954a, 1956, 1959, 1962, Singer and Digilio 1952, Horak 1964, Raithelhuber 1987, Lechner et al 2006, Brazil (mainly by Singer and Digilio 1952, Singer 1954b, 1956, 1959, 1973, Wartchow et al 2004, 2006, 2017, 2015a, 2015b, Dias and Cortez 2013, Bolivia (Singer 1959), Chile (Singer 1959, Horak 1964, Colombia (Singer 1973), Ecuador (Singer 1978, Reid et al 1981, French Guyana (Courtecuisse 1991), and Venezuela (Dennis 1953, 1970, Singer 1962, Pegler 1983. As there are no records of Pluteaceae from Paraguay, 4 species of Pluteus are recorded from Paraguay for the first time, contributing to the knowledge of agaricoid mycobiota in the country.…”

A new species of Pluteus section Celluloderma (Agaricales, Basidiomycota) from Southern Brazil

“…Other Brazilian species of Pluteus section Celluloderma bearing dermatocystidia are known: P. anomocystidiatus differs in the clavate to spheropedunculate pleurocystidia and filiform cheilocystida; P. brunneocrinitus in the brown fibrils on stipe and smaller basidiospores 4.5-5.5 × 4.5(-5.0) µm; P. chusqueae in the scarce pleurocystidia and narrowly fusiform or narrowly clavate to filiform dermatocystidioid elements; P. crinitus in the presence of long tuffs hairs on pileus surface; P. eludens in the pigmented cheilocystidia given a dark brown lamellaedge; P. longistriatus in the deeply deeply sulcate-striate over at least one-half the radius pileus and the elongate-fusiform or elongate-clavate dermatocystidia; P. necopinatus in the globose basidiospores 5.0-5.5 × 5.0-5.5 µm and fusiform more acute dermatocystidia; and P. thomsonii in the presence of rostrate cystidia (Wartchow et al, 2004;Menolli & Capelari, 2010;Menolli et al, 2015aMenolli et al, , 2015b.…”

“…Pluteus Fr. (Pluteaceae, Agaricales) is a pink-spored agaric genus relatively diverse in Brazil, on which at least 70 taxa are currently known (Putzke & Wartchow 2008, Menolli, De Meijer, Capelari, 2015a. Historically, Pluteus section Celluloderma Fayod comprises all species with a euhymenioderm or epithelial pileipellis sometimes presenting dermatocystidia, and lacking hymenial metuloids (see summary in Menolli & Cape-lari, 2016).…”
