Fresh basidiomes of the basidiomycete Amauroderma brasiliense were studied allowing the observation of new morphological structures for the species, i.e., gloeopleurous hyphae in the context and trama and dendrohyphidia. Scanning electron microphotograph showing the basidiospores ornamentation is provided for the first time.

A new species, Antrodia minuta, is described. It belongs to the Antrodia heteromorpha complex and is closely related to the East-Asian A. leucaena. Antrodia minuta is characterized by small-sized, mostly pileate basidiocarps, a dimitic hyphal structure with solid skeletal hyphae, and cylindrical basidiospores; its distribution is hemiboreal.

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.

Based on morphological and phylogenetic evidence, a new species of ganodermatoid fungi is recorded and described from the Brazilian Cerrado. After the species was placed in Furtadoa, this genus name was declared an illegitimate homonym by the Index Fungorum and MycoBank databases, according to Art. 53.1 of the International Code of Nomenclature for algae, fungi, and plants, thus requiring the need to replace Furtadoa. Therefore, Furtadomyces is proposed as the new name for the genus. The new species Furtadomyces sumptuosus is characterized by the combination of large basidiomata, multiple pilei, presence of radial striae on the pilear surface, an involute margin exposing the pore surface, and large, subglobose to ellipsoid (7.2–) 9.1–11.2 (–13.3) × (6.6–) 7.1–8.8 (–10.4) μm, double-walled basidiospores. It is closely related to Furtadoa biseptata, evidenced morphologically by the presence of two different septa in the generative hyphae of the context. Phylogeny, morphological description, illustrations, and comments for F. sumptuosus are presented, as well as two new combinations in Furtadomyces: F. biseptatus and F. brasiliensis.
... Then, it was transferred to Amauroderma (as A. corneri) based on Amauroderma-like basidiospores by observing a specimen from Atlantic Rain Forest in Brazil (Gulaid & Ryvarden 1998). The species was later considered as a synonymy of A. brasiliense (Ryvarden 2004b, Coelho et al. 2007, Gomes-Silva et al. 2015. However, based on morphological differences and high genetic divergence between the taxa Costa- Rezende et al. (2017) decided to maintain both A. brasiliense and A. corneri as independent species. ...

There have been several taxonomic studies on Brazilian species of Amauroderma over the past 10 years (Coelho et al. 2007, Gibertoni et al. 2008, Campacci & Gugliotta 2009, Gomes-Silva et al. 2010, Gomes-Silva & Gibertoni 2012, Campos-Santana & Loguercio-Leite 2013.

In Brazil, it has been recorded from Amazonia and Atlantic Forest (Ryvarden 2004, Coelho et al. 2007, Campacci & Gugliotta 2009, Gugliotta et al. 2015, and is reported for the first time from the Cerrado. Comments:-The soft basidiomata when fresh, a pale context dominated by clamped generative hyphae, the dimitic trama of the tubes with the presence of arboriform skeletal hyphae, as well the globose to ellipsoid spores (6) 7-10 × (5.5) 6-8 (9) µm characterize this species. ...
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.
... Amauroderma is macroscopically characterized by the stipitate basidiomata with variable color and consistency, and the pore surface. It has a dimitic hyphal system and subglobose to cylindrical, hyaline to pale yellow, and double-walled basidiospores with an ornamented or very rarely smooth exosporium and a columnar endosporium (Ryvarden 2004, Coelho et al. 2007). ...
Specimens of Amauroderma calcigenum and A. partitum from North and Northeast Brazil were studied and macro- and microscopical data are presented to support their segregation. Descriptions, pictures of the basidiomata and basidiospores in light microscopy and SEM images of hyphal pegs and basidiospores are provided.
... L' endospore est parfois amyloïde, rappelant celle de Leucophleps spinispora. Ce type de spores nous fait aussi penser à celles des Amauroderma (Coelho et al. 2007). Les données génétiques nous portent à croire que Polyporoletus est un genre autonome (voir figure 2), ce qui contredit l' opinion de Singer et al. (1945) et Hawksworth et al. (1995), qui classent ces espèces dans le genre Scutiger s. lat. ...
Scutiger s. lat. is found to include at least ten distinct genera: four previously named (Albatrellopsis; Albatrellus; Polyporoletus; Scutiger, amended) and six introduced here as new (Laeticutis, Neoalbatrellus, Polyporopsis, Polypus, Xanthoporus, Xeroceps). Keys to the ten segregate genera and to the species reported from North America and Europe are provided. The systematic position of these genera based on molecular analysis and the trophic strategies of the analyzed species are also discussed. Differing taxonomic points are examined, and the synonymy between Polyporopsis (Albatrellus) mexicanus and Polyporoletus sublividus is rejected. One new species, Polyporoletus bulbosus, and eleven new combinations are proposed.

Une clé des genres issus du démantèlement du genre Scutiger s. lat. est proposée, ainsi qu'une clé des espèces signalées en Amérique du Nord et en Europe.
