The Amsterdam Declaration on Fungal Nomenclature was agreed at an international symposium convened in Amsterdam on 19-20 April 2011 under the auspices of the International Commission on the Taxonomy of Fungi (ICTF). The purpose of the symposium was to address the issue of whether or how the current system of naming pleomorphic fungi should be maintained or changed now that molecular data are routinely available. The issue is urgent as mycologists currently follow different practices, and no consensus was achieved by a Special Committee appointed in 2005 by the International Botanical Congress to advise on the problem. The Declaration recognizes the need for an orderly transitition to a single-name nomenclatural system for all fungi, and to provide mechanisms to protect names that otherwise then become endangered. That is, meaning that priority should be given to the first described name, except where that is a younger name in general use when the first author to select a name of a pleomorphic monophyletic genus is to be followed, and suggests controversial cases are referred to a body, such as the ICTF, which will report to the Committee for Fungi. If appropriate, the ICTF could be mandated to promote the implementation of the Declaration. In addition, but not forming part of the Declaration, are reports of discussions held during the symposium on the governance of the nomenclature of fungi, and the naming of fungi known only from an environmental nucleic acid sequence in particular. Possible amendments to the Draft BioCode (2011) to allow for the needs of mycologists are suggested for further consideration, and a possible example of how a fungus only known from the environment might be described is presented.

Marasmius castaneophilus (from holotype; photo by H.Allı) 
Marasmius castaneophilus, a new agaric (Marasmiaceae, Agaricales, Basidiomycota) growing on sweet chestnut husks in Turkey, is described and illustrated. Its taxonomic position within the genus is discussed.
Antrodia serialiformis (JV0809/47, holotype). Basidiospores. 
A new and common polypore Antrodia serialiformis from eastern USA is described. The species is similar enough to A. serialis that previously both species were probably confused, but A. serialiformis seems exclusively confined to oaks. We present evidence that the new species differs from A. serialis based on much smaller basidiospores, mating incompatibility, rDNA sequence differences, and ecology.

Lichenostigma anatolicum (holotype). Ascus and ascospore outlines. 
Lichenostigma anatolicum is described as new from the squamules of a brown, pruinose Acarospora sp. on gypsaceous rocks in central Turkey. It is compared here with three other species of Lichenostigma also known to occur on Acarospora spp. and L. radicans described on vagrant Aspicilia species.
A neotype is designated for Acarospora interjecta. Acarospora pyrenopsoides is not recognized as occurring in Canada. Sarcogyne crustacea is a new name for Biatorella terrena, a rare terricolous species from southern California, which is revised.
A new species of Sarcogyne in the calcareous nivea group is described from the uplands of central Anatolia, Turkey. It is distinguished from other species in the group by its larger ascospores.
Phaeocandelabrum anam. gen. nov. is established to accommodate Sopagraha elegans, Ph. callisporum sp. nov. found on dead leaves of Cupania paniculata (Sapindaceae) and on the decaying leaf of an unidentified dicotyledonous plant in Brazil, and Ph. joseiturriagae found on decaying leaves of unidentified dicotyledonous plants in Brazil and Venezuela. Phaeocandelabrum callisporum is distinguished by complex, brown conidia composed of 2 globose, brown to dark central cells; 7–10 secondary hemispherical cells and, on each secondary cell, 3–4 hemispherical satellite cells, each with 5 simple, incurved branches. Phaeocandelabrum joseiturriagae is characterized by more less broadly Y-shaped to irregular brown conidia, each with a basal cell and two branches composed of 5–7 subglobose to globose cells, with 8–14 secondary cells each subtending 3–5 dichotomous or trichotomous minute tubercles. All three species are described and illustrated.

The rare cercosporoid hyphomycete Passalora acericola has been found for the first time in Poland, on Acer pseudoplatanus. Previously, this rare species has been found in only three other localities. It is described illustrated and discussed, based on the Polish material.
Volvariella acystidiata, an African species belonging to the V. gloiocephala-complex, is firstly reported from Europe on the basis of a collection made in northern Sardinia. This species is easily recognized by its medium size, white overall colour, large, ellipsoid to ovoid basidiospores and the lack of cystidia of any kind. The study includes a description, a photograph of fresh basidiomes and line drawings of relevant microanatomic traits.
Kalamarospora multiflagellata , from holotype (BPI 879811A). A. Conidia. B. Conidiophores, conidiogenous cells and conidia. The younger conidia show internal structure. Scale bar: 30 μm. 
Kalamarospora multiflagellata anam. gen. et sp. nov. is described and illustrated from rachides of dead leaves of Sabal palmetto collected in southwestern Florida, USA. The genus is characterized by having obclavate to ellipsoidal conidia internally filled with a mass of subhyaline, septate, 2-3 μm wide filaments growing upward from suprabasal cells at the bottom of the conidia and protruding apically or subapically as long, filiform, subhyaline or hyaline, sometimes 1-2 times dichotomously branched appendages. Conidia are borne on monoblastic, transversely striate, percurrently proliferating conidiogenous cells disposed on macronematous, cylindrical, solitary, unbranched, dark brown to blackish brown conidiophores. The conidial secession is rhexolytic, leaving a distinct, usually truncate frill up to 7 μm long, which remains attached to the basal cell of the conidia. Kalamarospora is compared with anamorphic genera and species having a similar internal conidial organization or morphologically close taxa with appendiculate conidia. Ellisembia britannica, Polytretophora calcarata, Pseudoacrodictys corniculata, Sporidesmiella sinensis, and Triposporium verruculosum are newly recorded from USA.

Note the spiral conidial filaments branching inwards in one plane and the striate-verrucose surface ornamentation of the conidial filament. Scale bars: 10 μm. 
Spiroplana centripeta is described as a new genus and species from Korea. Its spirally coiled conidia closely resemble those of the aeroaquatic genus Spirosphaera but its ecology differs totally, as it is parasitic to living Philadelphus and Deutzia leaves causing symptoms superficially similar to powdery mildew disease. No sexual state has been found, but molecular phylogenies inferred from ITS1-5.8S-ITS2 rDNA and partial nuLSU sequences support it within the Pleosporales (Dothideomycetes) and thus phylogenetically distinct from the generic type, Spirosphaera floriformis in the Leotiomycetes. Molecular phylogenies further show that Spirosphaera is polyphyletic and that generic diagnostic characters have evolved multiple times as an adaptation to conidium dispersal in the aeroaquatic niche. Morphologically, Spiroplana centripeta differs from Spirosphaera in its branching pattern, characterised by a main coil of cells in the conidial filament that give rise to 1-2 daughter filaments only on the inner side of the main coil. The daughter filaments then grow, coiling inwards with occasional additional branching to produce a tightly interwoven propagule enclosing air in a manner similar to aeroaquatic fungi. As primary branching takes place in one plane, the conidia are laterally flattened. In light of these molecular, morphological and ecological differences, a new genus is described. We believe the astounding similarity of the Spiroplana and Spirosphaera conidia is related to dispersal on the surface of a water film.

Cultures of Phyllosticta anamorph of Guignardia aesculi , 14-d old, inoculated from leaves of Aesculus hippocastanum . (A) on malt extract agar, (B) on rice agar. 
New localities of Guignardia aesculi on leaves of seven Aesculus species(×carnea, flava, hippocastanum, ×neglecta, parviflora, pavia, turbinata) were recorded in Europe. The teleomorph was found on overwintered leaves of A. hippocastanum in Slovakia. The occurrence of the Guignardia leaf blotch on A. hippocastanum and A. turbinata was also confirmed for the first time in South Korea. The causal fungus Guignardia aesculi and its conidial anamorph Phyllosticta sphaeropsoidea and spermatial synanamorph Leptodothiorella aesculicola are described in detail and illustrated. Pathogenicity of the fungus was confirmed by inoculating horse chestnut leaves with conidia.
Hirsutella liboensis was isolated from the larva of Cossidae (Lepidoptera) in Libo Natural Reserves, Guizhou Province. The fungus produces fasciculate synnemata and mono- and polyphialidic conidiogenous cells with necks twisted in two or three helical turns. Conidia are one-celled or (rarely) one-septate, fusiform or like orange segments that are enveloped in a mucous sheath. Morphological characters and phylogenetic analyses of ITS1-5.8S-ITS2 sequences support this fungus as a new species.

The Hawaiian mushroom Rhodocollybia laulaha was selected as a model to investigate patterns of gene flow between geographically isolated fungal populations from ecologically and bioclimatically varied sites. Its morphology (distinctive when compared to other members of the genus) and affinity for endemic Hawaiian forest suggested that it was endemic to Hawaii. However, speculation as to its closest non-Hawaiian relative and its overall placement within the genus was based on mostly anecdotal evidence. The present morphological and genetic research identifies a well-supported clade comprising R. laulaha individuals from across the Hawaiian Islands, reveals R. lignitilis (described in 2004 from the Neotropics) to be conspecific with R. laulaha, and identifies R. unakensis from Texas as a putative sister taxon. Different possible historical scenarios are discussed regarding the migration and establishment of R laulaha ancestors between the Americas and Hawaii. Rhodocollybia lignitilis is synonymized with R. laulaha, and Marasmius clavipes is transferred to Rhodocollybia.
Proposals for establishing a new International Code of Mycological Nomenclature are deemed unwise and unrealistic.

Molecular identification of Aspergillus sect. Flavi isolates
Aspergillus sect. Flavi isolates from Turkish dried figs have been determined using PCR amplification of the ITS1 and ITS2 rDNA regions. Species were identified by comparing partial 18S rDNA sequences from 57 different fungal isolates comprising 5 A. parasiticus strains, 1 A. tamarii strain, and 51 A. flavus strains with known ribosomal sequences using BLAST search. Sequence comparisons between the isolates and reference cultures showed a 95-99% similarity; morphological and phenotypical character comparisons of the same strains produced equally close similarities. The sole exception was an aflatoxin B1 and B2 producing strain that cannot produce cyclopiazonic acid; this strain, originally identified as A. flavus, was instead found to represent A. parasiticus.
List of Argentine fungal strains employed in this survey, their geographical location and BAFC number.
The objective of this study was to ascertain the usefulness of the AFLP technique in assessing genetic diversity among 47 strains belonging to three Ascomycota genera and as a tool for solving taxonomic problems in related morphological species. Four MseI +1 primers were assayed in combination with two EcoRI +2 and four EcoRI +3 primers. In the present study both +2 and +3 EcoRI primers were informative, but EcoRI +2 produced profiles with high complexity. The addition of the extra selective nucleotide reduced the complexity of the banding patterns generating easily readable patterns to evaluate genetic diversity within and among species. Of the three ascomycetous genera assessed in this study, Colletotrichum (Glomerellaceae) presented the highest proportion of polymorphic AFLP loci, followed in order by Iodophanus (Pezizaceae) and Saccobolus (Ascobolaceae).

Two Clathrus specimens were collected in Northeastern Brazil during the rainy season in 2008. One specimen was identified as C. chrysomycelinus and the other is described as a new species, C. cristatus, which is distinguished by its pale red to pink receptacle and crests along the edge. Full descriptions with illustrations of the collected specimens and a key to species of Clathrus from Brazil are provided.
In order to increase the knowledge of puffballs in Brazil, specimens were collected in the State of Pernambuco, an understudied area in the Northeast Region, between June 2008 and April 2009. Arachnion album, Bovista dominicensis, and Morganella fuliginea are recorded for the first time from this region. Bovista grandipora, collected on soil among grass, is described as a new species in the Bovista delicata-complex. This species is characterized by a thin whitish exoperidium, an olive-brown endoperidium, punctate to verruculose, apedicellate basidiospores (4-5.5 μm diam.), and capillitium of the Lycoperdon-type with large pits in the hyphal units. Descriptions and illustrations, including SEM micrographs of basidiospores, are presented for each of the identified species, and keys to the recorded species of Arachnion, Bovista, and Morganella from Brazil are also provided.
A new arbuscular mycorrhizal fungus, Cetraspora helvetica, was found in three Swiss agricultural soils: a no-till crop production system and two temporary grasslands. It forms white spores, 210-270 μm diam, on dark yellow sporogenous cells. The spores have three walls: a triple-layered outer, a bi-layered middle and a triplelayered inner wall. The spore surface is crowded with convex warts, 5-12 μm diam at the base and 1.5-5.0 μm high. The germination shield is hyaline with multiple (6-10) lobes. Glomerospores of two other Gigasporineae spp. have also three walls, multiple-lobed hyaline germination shields, and projections on the outer spore surface: C. spinosissima and C. striata. However, spores of these fungi are substantially pigmented (ochraceous yellow to rust) and crowded with short, thin spines or fingerprint-like processes, respectively. Partial sequences of the 28S ribosomal gene place the new species adjacent to C. spinosissima, C. pellucida, and C. gilmorei. Phylogenetic analyses demonstrate the monophyly of the two genera Racocetra and Cetraspora within the Racocetraceae.

Surveys of fungi associated with stained vascular tissue in kiwifruit vines in New Zealand have consistently revealed Phialophora-like fungi. Phylogenetic analyses based on DNA sequences have shown most of these to be Leotiomycetes. The teleomorph of the most common species isolated from stained kiwifruit wood has been found on fallen wood in native forests, and it is described here as Neobulgaria alba sp. nov. Other species isolated from kiwifruit wood matched Cadophora and Mollisia spp. reported from similar symptoms from kiwifruit and other hosts in other countries.
Phylogramme de strict consensus des séquences ribosomales ITS1, 5.8S et ITS2 calculé par le programme MrBayes (Huelsenbeck & Ronquist 2001; 1 000 000 générations). A: Albatrellopsis; B: Neoalbatrellus; C: Albatrellus; D: Polyporoletus sylvestris E: Xeroceps; F: Scutiger; G: Polyporoletus bulbosus; H: Jahnoporus; I: Xanthoporus; hors groupe: Diplomitoporus crustulinus. Le clade C correspondant au genre Albatrellus est très bien soutenu (100%) avec l' espèce-type A. ovinus (figure 2). Avec l'analyse des séquences ITS (fig. 1), le genre Albatrellus apparaît le plus riche en espèces, avec A. subrubescens, A. ovinus, A. citrinus et A. citrinus s. lat. et peut-être A. tianschanicus. Pour ce dernier, l'analyse moléculaire ne fournit pas de réponse significative. Le clade Scutiger s. str. (A. pes-caprae et A. ellisii) est assez peu soutenu sur la fig. 1, mais le rapprochement est quand même fortement suggéré. Ces deux espèces sont regroupées dans un même clade par l'analyse des séquences LSU (Zheng 2006). Albatrellus caeruleoporus et A. yasudae (fig. 1) sont regroupées sur un clade monophylétique bien soutenu avec l'ITS. Les séquences LSU n' ont pas été

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. French Le genre Scutiger au sens traditionnel renferme au moins dix genres distincts: Albatrellopsis, Albatrellus, Polyporoletus et Scutiger, ici amendés, et six introduits comme nouveaux: Laeticutis, Neoalbatrellus, Polyporopsis, Polypus, Xanthoporus, Xeroceps. 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. La position systématique de ces genres est discutée d'après les résultats d'analyses moléculaires, ainsi que les caractéristiques trophiques des espèces étudiées. Divers points de taxinomie sont étudiés; en particulier la synonymie entre Polyporopsis (Albatrellus) mexicanus et Polyporoletus sublividus est rejetée. Une nouvelle espèce, Polyporoletus bulbosus, et onze combinaisons nouvelles sont proposées.
