In this study, we used a replicated factorial design to separate the individual and interacting effects of two main components of a severe hurricane - canopy opening and green debris deposition on leaf litter decay in the tabonuco forest in the Luquillo Mountains of Puerto Rico. We quantify changes in percent mass remaining (PMR), the concentration and absolute amounts of various chemical elements using fresh (green) and senesced leaf litter contained in litterbags of two different mesh sizes. Mass loss was significantly slowed by canopy trimming. There was no significant effect of debris treatment on the PMR of the litter. Canopy trimming increased the percent of initial N, Al, Ca, Fe, and Mg remaining and decreased the percent of initial Mn remaining compared with not trimmed plots. Debris addition increased the percent of initial N and P remaining and decreased the percent of initial Al, and Fe remaining in the decomposing litter compared to no debris added plots. Of the elements studied, only Al and Fe accumulated above 100% of initial. Accumulation of Al and Fe in the canopy trimmed and no debris plots. is most likely dominated by the adsorption of these ions onto the surfaces of the decaying litter. Overall, P showed a rapid initial loss during the first 0.2. yr followed by steady loss. Nitrogen was lost steadily from leaf litter. The PMR of fresh and senesced litter was significantly affected by mesh size, with a higher mass remaining in small mesh bags. Fresh litter decayed faster than senesced litter; following patterns of initial N and P concentrations (higher in the former litter type). We found a significantly negative correlation between the Margalef index of diversity for the litter arthropods contained in the litterbags and the PMR, suggesting functional complexity is an important determinant of decay in this forest. Our results imply hurricanes can differentially impact litter decomposition and associated nutrient release via canopy opening and litter inputs. © 2014.

The family Tricholomataceae, contained within the Tricholomatoid clade, has traditionally been one of the largest families of the Agaricales. However, in this sense it is highly polyphyletic and requires emendation. Here, we present a phylogeny of the Tricholomatoid clade based on nucleotide sequence data from two nuclear ribosomal RNA genes (large subunit and small subunit) and the second-largest subunit of RNA polymerase II (rpb2). Our aim is to delimit the Tricholomataceae and identify monophyletic groups within the Tricholomatoid clade. We also infer a separate phylogeny, based on the three genes above, in addition to sequences of the nuclear ribosomal internal transcribed spacers (ITS), in order to evaluate generic-level boundaries within the Tricholomataceae s.str. Based on this analysis we recover seven monophyletic genera within the Tricholomataceae s.str. that correspond to Leucopaxillus, Tricholoma, Pseudotricholoma stat. nov., Porpoloma s.str., Dennisiomyces, Corneriella gen. nov., and Albomagister gen. nov. Of the 98 genera that have been traditionally assigned to the Tricholomataceae sensu Singer, only four can be placed within it (Tricholoma, Porpoloma, Dennisiomyces, Leucopaxillus). The genus Porpoloma is highly polyphyletic and divided into four genera: Porpoloma s.str., Corneriella gen. nov., Pseudotricholoma stat. nov., and Pogonoloma stat. nov. In all, four new genera are proposed. Taxonomic descriptions, and a key to genera of the Tricholomat aceae as emended here are also presented. © International Association for Plant Taxonomy (IAPT) 2014.

Four species of the ectomycorrhizal (ECM) genus Sarcodon (Bankeraceae, Thelephorales, Basidiomycota) are described as new to science. Sarcodon pakaraimensis sp. nov. is described from forests dominated by the ECM trees Pakaraimaea dipterocarpacea (Dipterocarpaceae) and Dicymbe jenmanii (Fabaceae subfam. Caesalpinioideae) in the Pakaraima Mountains of Guyana. Sarcodon portoricensis sp. nov. is described from lower montane wet forest within the El Yunque National Forest of Puerto Rico. Sarcodon quercophilus sp. nov. and Sarcodon umbilicatus sp. nov. are described from Quercus (Fagaceae) cloud forests within the Maya Mountains of Belize. The discovery of these species is significant given that the majority of the approximately 87 described Sarcodon species are north temperate or boreal in distribution and frequently associate with coniferous host plants; these constitute the most recent records for Sarcodon from the greater Neotropics. Each of the new species is morphologically consistent with accepted diagnostic characters for Sarcodon: pileate-stipitate stature, a dentate hymenophore, determinate basidiomatal development, fleshy, non-zonate context and brown, tuberculate basidiospores. DNA (ITS) sequence analysis corroborated the generic placement of S. pakaraimensis, S. portoricensis, S. quercophilus and S. umbilicatus and, along with morphological differences, supported their recognition as distinct species. Macromorphological, micromorphological, habitat and DNA sequence data from the nuc rDNA internal transcribed spacer region (ITS) are provided for each of the new species. A key to Neotropical Sarcodon species and similar extralimital taxa is provided.

Profound changes to the taxonomy and classification of polypores have occurred since the advent of molecular phylogenetics in the 1990s. The last major monograph of North American polypores was published by Gilbertson and Ryvarden in 1986–1987. In the intervening 30 years, new species, new combinations, and new records of polypores were reported from North America. As a result, an updated checklist of North American polypores is needed to reflect the polypore diversity in there. We recognize 492 species of polypores from 146 genera in North America. Of these, 232 species are unchanged from Gilbertson and Ryvarden’s monograph, and 175 species required name or authority changes. In addition, 40 new species and 45 new records published since that monograph are included in the checklist. Among the 492 species of polypores, 486 species from 143 genera belong to 11 orders, while six other species from three genera have uncertain taxonomic position at the order level. Three orders, viz. Polyporales, Hymenochaetales and Russulales, accommodate most of polypore species (93.7 %) and genera (88.8 %). We hope that this updated checklist will inspire future studies in the polypore mycota of North America and contribute to the diversity and systematics of polypores worldwide. © 2016, German Mycological Society and Springer-Verlag Berlin Heidelberg.

Fungal secondary metabolism has become an important research topic with great biomedical and biotechnological value. In the postgenomic era, understanding the diversity and the molecular control of secondary metabolites (SMs) are two challenging tasks addressed by the research community. Discovery of the LaeA methyltransferase 10 years ago opened up a new horizon on the control of SM research when it was found that expression of many SM gene clusters is controlled by LaeA. While the molecular function of LaeA remains an enigma, discovery of the velvet family proteins as interaction partners further extended the role of the LaeA beyond secondary metabolism. The heterotrimeric VelB-VeA-LaeA complex plays important roles in development, sporulation, secondary metabolism, and pathogenicity. Recently, three other methyltransferases have been found to associate with the velvet complex, the LaeA-like methyltransferase F and the methyltransferase heterodimers VipC-VapB. Interaction of VeA with at least four methyltransferase proteins indicates a molecular hub function for VeA that questions: Is there a VeA supercomplex or is VeA part of a highly dynamic cellular control network with many different partners?. © 2015 Sarikaya-Bayram, Palmer, Keller, Braus and Bayram.

A new species, Phlebopus mexicanus, is described from southern tropical rainforests of Mexico based on morphological and molecular characters. Several features distinguish this species from others of Phlebopus including the medium to small basidiomata with olivaceous brown tomentose pileus that becomes finely areolate cracked with age, the dark yellow brown pruina covering most of the stipe, the pale yellow flesh of pileus and stipe that slowly turns blue when exposed, and the lack of hymenial cystidia. Phylogenetic analyses using nLSU sequences support the recognition of this new morphological species in the Sclerodermatineae. Our analyses also suggest that P. portentosus and P. marginatus are not conspecific and relationships of Old World taxa of Phlebopus need further scrutiny. A key to all known New World taxa is provided. © 2015 Pacific Northwest Fungi Project. All rights reserved.
