Neotropical Ganodermataceae (Basidiomycota): Amauroderma sprucei and A. dubiopansum
Abstract and Figures
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 particular, regarding neotropical Amauroderma species there are taxa which not fit within the phylogenetic delimitation of Amauroderma s.str. senso Costa-Rezende et al. (2016), such as Amauroderma sprucei which distinguishes within the genus by its whitish context with hyaline dextrinoid skeletal hyphae and a vivid orange pore surface in most of the specimens (Decock & Herrera-Figueroa 2006). There are also monomitic or nearly so species within Amauroderma, as A. trichodermatum and A. brasiliense (Robledo et al. 2015), as well as species with basidiospores with reticulate endosporium (A. ...

... 1730m above sea level, 21 May 2007, Robledo 1507 Notes -The dull concentric zonate pilear surface, the whitish context, the ochraceous to vivid orange pore surface, the small pores (5-7(-8) pores/mm), a crust with a short trichoderm in the pilear surface, the strongly dextrinoid skeletal hyphae and the predominantly subglobose basidiospores ((7-)8-10 × 7-9 µm), with conspicuous hollow columnar ornamentation are characteristic of this species. The species was described with a di-trimitic hyphal system, with generative and vegetative hyphae in all portions of basidioma, and the trama of tubes as dimitic with arboriform skeletal hyphae (Decock & Herrera-Figueroa 2006). In our observations, the hyphal system is considered dimitic. ...
Ganodermataceae is a remarkable group of polypore fungi, mainly characterized by particular doublewalled
basidiospores with a coloured endosporium ornamented with columns or crests, and a hyaline smooth
exosporium. In order to establish an integrative morphological and molecular phylogenetic approach to clarify
relationship of Neotropical Amauroderma s.lat. within the Ganodermataceae family, morphological analyses, including
scanning electron microscopy, as well as a molecular phylogenetic approach based on one (ITS) and four
loci (ITS-5.8S, LSU, TEF-1α and RPB1), were carried out. Ultrastructural analyses raised up a new character for
Ganodermataceae systematics, i.e., the presence of perforation in the exosporium with holes that are connected with
hollow columns of the endosporium. This character is considered as a synapomorphy in Foraminispora, a new genus
proposed here to accommodate Porothelium rugosum (≡ Amauroderma sprucei). Furtadoa is proposed to accommodate
species with monomitic context: F. biseptata, F. brasiliensis and F. corneri. Molecular phylogenetic analyses
confirm that both genera grouped as strongly supported distinct lineages out of the Amauroderma s.str. clade.

... According to our observations, the basidiospores are globose to subglobose (Q = 1.0 -1.15, ave-Q = 1.13). The range from ochraceus to orange in the hymenophore coloration was also observed by Decock & Herrera-Figueroa (2006), who synonymized A. dubiopansum and A. sprucei mainly based in the plasticity of this feature. ...
... Amauroderma sprucei is a common neotropical species and does not share morphological features with either Ganoderma or Tomophagus, which could explain the conflicting topologies. The species is characterized by a whitish context, an ochraceus to vivid orange pore surface in some specimens, strongly dextrinoid skeletal hyphae and predominantly subglobose spores [(7.0) 8.0-10 × 7-9 µm], with conspicuous columnar ornamentation (Decock & Herrera-Figueroa 2006). Thus, further morphological and phylogenetic studies should be performed to clarify its relationships at generic level. ...
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.

A survey of lignolytic basidiomycetes from Mondaí (27º06'16"S, 53º24'07"W) in the Brazilian state of Santa Catarina has revealed nine previously unrecorded species: Dacryopinax elegans, Cotylidia aurantiaca, Hymenochaete rubiginosa, Inonotus rickii, Phellinus rhytiphloeus, Echinoporia aculeifera, Oxyporus obducens, Amauroderma sprucei, and Pseudofavolus miquelii. Comments about the species and illustrations are provided. Introduction Among the estimated 1.5 million fungal species, only 74,000 to 120,000 species have been described. With limited human and financial resources, a total inventory is not possible within any reasonable time frame, which is estimated to be 1290 years at the current rate (Garibay-Orijel et al. 2009). Within the field of mycology, there are numerous studies about the diversity of macrofungi. However, Gilbert & Souza (2002) and Piepenbring (2007) point out that a significant portion of the fungal taxa from tropical forests has not yet been described.

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.

Background
Foraminispora rugosa is a species reported from Brazil, Venezuela, French Guiana, Costa Rica and Cuba. It is a basidiomycete in the Ganodermataceae family. In this study, both chemical composition and cytotoxicity of the ethanolic extract of F. rugosa were investigated for the first time.
Results
Phylogenetic analysis confirmed the identification of the specimens, and the results of cytotoxicity assays showed that at concentrations of 7.8–500.0 µg/mL the ethanolic extract displayed weak cytotoxicity against the tested cell lines. Five oxylipins were identified by ultra high performance liquid chromatography coupled with quadrupole time-of-flight and mass spectrometry (UHPLC-QTOF–MS).
Conclusions
This study provides new insights into the current knowledge of bioactive compounds produced by macrofungi, and provides data for future biological assays with relative selectivity and safety.

Macrofungi from exclusive Brazilian biome of semi-arid region are poorly known and more efforts are
necessary to document the diversity and distribution of this group among all the different ecosystems of the Caatinga. Sixty
one exsiccata kept at ALCB, CEPEC, HUVA and IPA herbaria were revised which corresponded to 36 species. Fourteen of
these, Auricularia polytricha, Amauroderma partitum, A. sprucei, Dichomitus cavernulosus, Flabellophora parva, Flaviporus hydrophilus, Ganoderma resinaceum, Hexagonia papyracea, Perenniporia aurantiaca, Phellinus shaferi, Polyporus ianthinus, Rigidoporus lineatus, R. ulmarius, and Steccherinum reniforme, are first records for the Caatinga biome.
A study of 65 species of polypores proceeding from 197 specimens collected in five localities of the Biosphere Reserve El Cielo, Tamaulipas, México is presented. Four of these species belong to Ganodermataceae, 18 to Hymenochaetaceae and 43 to Polyporaceae. Tree species are recorded for the first time to Mexico and they are Humphrey coffeatum, Phellinus sonorae and Diacanthodes novoguinensis.
