During a polypore survey in the Cerrado (Mato Grosso state, Brazil), Amauroderma specimens were collected and some of them deserved special taxonomic attention due to their intermediate morphology between A. calcigenum and A. partitum. A comparative study of the types and reference material, as well as phylogenetic analysis, led us to conclude that these speci- mens represent an undescribed species, presented here as Amauroderma calcitum. In addition A. brasiliense is presented as a new record for the Brazilian Cerrado. Illustrations, taxonomic analyses and a discussion are presented for each taxon, and a key to the Amauroderma species from Brazil is provided. A phylogenetic discussion about the genus is also presented.
... Species of this family, except the genus Haddowia, are widely distributed in the tropics with records in several brazilian ecosystems (Gibertoni & Cavalcanti 2003, Silveira et al. 2008, Baltazar & Gibertoni 2009, Campacci & Gugliotta 2009, Drechsler-Santos et al. 2009, Gomes-Silva & Gibertoni 2009, Gibertoni & Drechsler-Santos 2010, Gugliotta et al. 2010, Costa-Rezende et al. 2016, Bononi et al. 2017. However, knowledge about this family in the Cerrado biome is restricted to records of 17 species, with a predominance of the genera Amauroderma and Ganoderma (Gibertoni & Drechsler-Santos 2010, Abrahão et al. 2012, Maia et al. 2015, Costa-Rezende et al. 2016, Bononi et al. 2017. ...

Additions to the knowledge of Ganodermataceae in brazilian Cerrado). As a cosmopolitan family, Ganodermataceae has as distinctive characteristic the presence of double-walled basidiospore: the inner wall thick and ornamented, and the outer wall smooth. Even with the increasing interest in this family, the species are still poorly known in different regions of the brazilian territory, such as in the central Brazil. This study presents new distribution remarks of Ganodermataceae species in different sites of the biome Cerrado, in the Midwest region. We found 23 specimens from five species which are distributed into three genera, Amauroderma, Foraminispora and Ganoderma. From those species, one is a new record for the Cerrado (A. exile), four are new for the State of Goiás A. exile, F. rugosa, G. multiplicatum and G. stipitatum and one for the Distrito Federal (G. stipitatum). Amauroderma aurantiacum is rediscovered in Goiás after 88 years. This study contributes to improving the knowledge regarding the geographic distribution of these taxa in Brazil.

... The studied specimens of Amauroderma represented 20 species, six of which are new to science: Amauroderma albostipitatum, A. floriformum, A. laccatostipitatum, A. ovisporum, A. sessile and A. subsessile. Of the species previously recorded in Brazil (Campacci & Gugliotta 2009), A. boleticeum (Pat. & Gaillard) Torrend (1920: 132), A. coltricioides T.W. Henkel, Aime & Ryvarden (2003: 615), A. oblongisporum J.S. Furtado (1968: 208), A. pseudoboletus (Speg.) ...
... Six new species of Amauroderma are described, all of them from the Amazonia dominion, except for A. subsessile, also found in Central America. These species, as well as A. boleticeum and A. elegantissimum, were not registered in the Brazilian Atlantic Rain Forest, an area where collecting specimens of Ganodermataceae has been rather intense (Gibertoni et al., 2004;Loguercio-Leite et al. 2005;Torres-Torres et al., 2008Campacci & Gugliotta 2009;Westphalen et al., 2010;Gomes-Silva et al., 2011a;Gugliotta et al., 2011;Campos-Santana & Loguercio-Leite, 2013;Gomes-Silva & Gibertoni, 2012) when compared to the Brazilian Amazonia (Gomes-Silva et al., 2011a, b;Martins-Junior et al., 2011;Torres-Torres et al., 2008. In contrast, only A. oblongisporum, A. picipes and A. renidens seem to be restricted to the Atlantic Rain Forest, suggesting that, besides being underexplored, the Amazonia has higher diversity of species of Amauroderma than the Atlantic Rain Forest. ...

From 2007 to 2014, specimens of Amauroderma were collected mostly in North and Northeast Brazil. Additionally, material deposited in herbaria was reviewed. The analysed specimens represented 20 species, six of them new to science: Amauroderma albostipitatum, A. floriformum, A. laccatostipitatum, A. ovisporum, A. sessile and A. subsessile. Twelve species, three of them new, had their ITS and/or LSU region of the DNA sequenced. According to the results, Amauroderma is not monophyletic; A. partitum and A. schomburgkii are macro-morphologically variable species; the synonym of A. calcigenum with A. partitum is not supported, and the use of macro- and micro-morphological characters is a useful tool to delimit species of the genus.
... A. oblongisporum was reported in Brazil by Campacci and Gugliotta (2009), and it is putatively the only Amauroderma species with a shared occurrence between Africa and South America. However, the parasitic habit of Amauroderma species has been suggested to cause strong endemism in species of the genus owing to coevolution with hosts . ...
... The poroid basidiomycetes have been continuously surveyed in Southern Brazil, mainly in the last two decades (e.g. Drechsler-Santos et al. 2008, 2010, Silveira et al. 2008, Baltazar and Gibertoni 2009, Campacci and Gugliotta 2009, Coelho et al. 2009, Meijer 2010, Gerlach et al. 2013). However, globally, the poroid Hymenochaetaceae have been less addressed than other groups (Baltazar and Gibertoni 2009, Baltazar et al. 2009, Gerlach et al. 2013. ...

Ganodermataceae is one of the main families of macrofungi since species in the family are both ecologically and economically important. The double-walled basidiospores with ornamented endospore walls are the characteristic features of Ganodermataceae . It is a large and complex family; although many studies have focused on Ganodermataceae , the global diversity, geographic distribution, taxonomy and molecular phylogeny of Ganodermataceae still remained incompletely understood. In this work, taxonomic and phylogenetic studies on worldwide species of Ganodermataceae were carried out by morphological examination and molecular phylogenetic analyses inferred from six gene loci including the internal transcribed spacer regions (ITS), the large subunit of nuclear ribosomal RNA gene (nLSU), the second largest subunit of RNA polymerase II gene ( rpb2 ), the translation elongation factor 1-α gene ( tef1 ), the small subunit mitochondrial rRNA gene (mtSSU) and the small subunit nuclear ribosomal RNA gene (nSSU). A total of 1 382 sequences were used in the phylogenetic analyses, of which 817 were newly generated, including 132 sequences of ITS, 139 sequences of nLSU, 83 sequences of rpb2 , 124 sequences of tef1 , 150 sequences of mtSSU and 189 sequences of nSSU. The combined six-gene dataset included sequences from 391 specimens representing 146 taxa from Ganodermataceae . Based on morphological and phylogenetic analyses, 14 genera were confirmed in Ganodermataceae : Amauroderma , Amaurodermellus , Cristataspora , Foraminispora , Furtadoella , Ganoderma , Haddowia , Humphreya , Magoderna , Neoganoderma , Sanguinoderma , Sinoganoderma , Tomophagus and Trachydermella . Among these genera, Neoganoderma gen. nov. is proposed for Ganoderma neurosporum ; Sinoganoderma gen. nov. is proposed for Ganoderma shandongense ; Furtadoella gen. nov. is proposed to include taxa previously belonging to Furtadoa since Furtadoa is a homonym of a plant genus in the Araceae ; Trachydermella gen. nov. is proposed to include Trachyderma tsunodae since Trachyderma is a homonym of a lichen genus in the Pannariaceae . Twenty-three new species, viz., Ganoderma acaciicola , G. acontextum , G. alpinum , G. bubalinomarginatum , G. castaneum , G. chuxiongense , G. cocoicola , G. fallax , G. guangxiense , G. puerense , G. subangustisporum , G. subellipsoideum , G. subflexipes , G. sublobatum , G. tongshanense , G. yunlingense , Haddowia macropora , Sanguinoderma guangdongense , Sa. infundibulare , Sa. longistipitum , Sa. melanocarpum , Sa. microsporum and Sa. tricolor are described. In addition, another 33 known species are also described in detail for comparison. Scanning electron micrographs of basidiospores of 10 genera in Ganodermataceae are provided. A key to the accepted genera of Ganodermataceae and keys to the accepted species of Ganoderma , Haddowia , Humphreya , Magoderna , Sanguinoderma and Tomophagus are also provided. In total, 278 species are accepted as members of Ganodermataceae including 59 species distributed in China.

The fungi diversity in Brazil is not fully known yet, mainly in Serra de Maracaju, which is located in the central portion of the State of Mato Grosso do Sul, in the center-western region of Brazil. Samples were taken from different phytophysiognomies of the Cerrado, the dominating biome of that region, in areas where Cerrado and pasture alternate, in the municipality of Corguinho. Of the species identified, 18 are new citations for Brazil, as they are not included in the List of Brazilian Flora (fungi), and 36 are recorded for the first time for [the State of] Mato Grosso do Sul. As a total, 62 species were collected in nine excursions during 2014 and 2015. Out of this total, 15 species are deemed edible, four are toxic, ten are medicinal, two are used in bioremediation processes, and one is bioluminescent, according to the literature.

During the survey of wood-inhabiting fungi in Cuba, several specimens of an Amauroderma species with a brightly colored pore surface, viz. bright orange, were collected, and subsequently identified to A. dubiopansum. However, the status of the latter name, particularly its taxonomic relationship with A. sprucei remained uncertain. In order to confirm the identification, the type specimens of A. dubiopansum and A. sprucei were studied and compared to our various collections. We have concluded that A. sprucei and A. dubiopansum are synonyms, the former epithet having priority.

In this study of diversity of lignicolous aphyllophoroid Basidiomycota in an Atlantic Forest fragment in the semi-arid Caatinga region of the State of Bahia, Brazil, a total of 26 species were collected. Most of the taxa are pantropical, white-rot species, belonging to the polyporoid clade. Pycnoporus sanguineus, Phellinus gilvus and Lentinus crinitus were the most frequently collected taxa, both in number of specimens and in occurrence along the sampling period. Although surrounded by the semi-arid Caatinga vegetation and presumably isolated from the conventional Atlantic Forest region, the mycota of the submontane fragment seems to have no marked differences from the mycota of other fragments situated in the traditional domain of Atlantic Forest in lower altitudes.
