We recorded in a tropical dry forest in the northeast of Colombia (Cesar Dept.) 12 species of macrofungi
previously unknown for the country; Amanita aureofloccosa, A. crebresulcata (Amanitaceae), Daedalea
flavida (Fomitopsidaceae), Ganoderma resinaceum (Ganodermataceae), Marasmius cohortalis
(Marasmiaceae), Phellinus merrilli, P. aff. umbrinellus (...

... Morphological analyses: The observed macro-and microscopical characteristics of the specimen ( Figure 1) agreed with the reference descriptions of P. beniensis (Heinemann & Rammeloo, 1982;Barbosa, 2016;Palacio et al., 2015;Calaça et al., 2018). Macroscopically, the specimen identified as P. beniensis was characterized by a pileus up to 200 mm in diameter, robust stipe, and small pores. ...

In recent decades, mushrooms have been recognized as an important resource and efforts to characterize their potential to aid nutrition and human health have increased. Phlebopus beniensis specimen from a semi-urban community in Paraguay were analyzed for its biochemical properties, nutritional value, and toxicity. The species was identified by morpho-anatomical and molecular tools. Analyses for antioxidants by Ultraviolet-visible (UV-VIS) and nutritional content revealed that P. beniensis is a favorable source of antioxidants, proteins, carbohydrates, dietary fiber, and fats. Spectrometry through Gas Chromatography-Mass Spectrometry (GC-MS) further showcased other mycochemicals such as the specific phenolic, antioxidant, and fatty acid compounds that serve important biological roles in human diets. Applying an ethnomycological framework across local Paraguayan populations, we also report accounts of histories, knowledge, and usage of P. beniensis in South America among settlers and Paraguayan people.
... Distribution: This species is currently known in Brazil (Wartchow et al. 2015), Colombia (Palacio et al. 2015), Ghana (Pegler 1968;Wartchow et al. 2015), the Southern Democratic Republic of the Congo (Bas 1969), and Thailand (this study). Remarks: Morphologically, Amanita aureofloccosa is unique among congeners by having a pulverulent, bright orange-yellow volva remnant on its pileus, a slender stipe covered by orange-yellow floccose scales, a globose to subglobose, amyloid basidiospore and the lacking clamps in all parts of basidiomata. ...
The genus Amanita, comprising three subgenera and eleven sections, is one of the most species diverse genera within the class Agaricomycetes. To date, 54 species have been validly reported from Thailand. During surveys of macro-fungi in northern Thailand in 2019 and 2020, three Amanita species were collected and identified as the members of Amanita sect. Lepidella based on morphological and molecular data. Among the three species, two species were identified as A. aureofloccosa and A. manicata and A. aureofloccosa is reported as a new record in Thailand. Interestingly, the third species was distinct from all other known species within sect. Lepidella. We describe the third species as a new species, namely A. albicarnosa. All these three taxa are documented with morphological characteristics, a phylogenetic tree, line drawings, color photographs, and comparisons with morphologically similar taxa. A distributional map of the sampling sites and a key to the Thai species of Amanita sect. Lepidella are also provided.
... More recently, 25 species have described from the South American tropics including 11 from Colombia (Tulloss et al. 1992, Tulloss & Franco-Molano 2008, nine from Brazil (Bas & De Meijer 1993, Menolli et al. 2009, Wartchow et al. 2009, Wartchow et al. 2013, Wartchow 2015, Wartchow 2016, Wartchow & Cortez 2016, four from Guyana (Simmons et al. 2002), and one from Ecuador (Wartchow & Gamboa-Trujillo 2012). An additional six species previously described from other regions have been recorded in tropical South America (Tulloss & Halling 1997, Sobestiansky 2005, Wartchow & Tulloss 2007, Lechner & Alberto 2008, Palacio et al. 2015. This steady accrual of new taxa suggests that many South American Amanita species remain to be discovered. ...
New species of Amanita subgen. Lepidella are described from Guyana. Amanita cyanochlorinosma sp. nov., Amanita fulvoalba sp. nov., and Amanita guyanensis sp. nov. represent the latest additions to the growing body of newly described ectomycorrhizal fungi native to Dicymbe-dominated tropical rainforests. Macro- and micromorphological characters, habitat, and DNA sequence data for the ITS, nrLSU, rpb2, and ef1-α are provided for each taxon, and β-tubulin for most. Distinctive morphological features warrant the recognition of the three new species and a molecular phylogenetic analysis of taxa across Amanita subgen. Lepidella corroborates their infrageneric placements.
