Sporothrix (Sordariales, Ascomycota) is a well-supported monophyletic lineage within the Ophiostomatales, species of which occur in a diverse range of habitats including on forest trees, in the soil, associated with bark beetles and mites as well as on the fruiting bodies of some Basidiomycota. Several species have also been reported as important human and animal pathogens. During surveys of insect- and wound-associated Ophiostomatales from hardwood trees in Poland, many isolates with affinity to Sporothrix were recovered. In the present study, six undescribed Sporothrix spp. collected during these surveys are characterized based on their morphological characteristics and multi-locus phylogenenetic inference. They are described as Sporothrix cavum, Sporothrix cracoviensis, S. cryptarchum, S. fraxini, S. resoviensis, and S. undulata. Two of the Sporothrix spp. reside in the S. gossypina-complex, while one forms part of the S. stenoceras-complex. One Sporothrix sp. is a member of lineage F, and two other species grouped outside any of the currently defined species complexes. All the newly described species were recovered from hardwood habitats in association with sub-cortical insects, wounds or woodpecker cavities. These species were morphologically similar, with predominantly asexual states having hyaline or lightly pigmented conidia, which produce holoblastically on denticulate conidiogenous cells. Five of the new taxa produce ascomata with necks terminating in long ostiolar hyphae and allantoid ascospores without sheaths. The results suggest that Sporothrix species are common members of the Ophiostomatales in hardwood ecosystems of Poland.

Metsamardikate (Coleoptera) uued liigid Eestis The article presents faunistic data on 85 species of Coleoptera new to the Estonian fauna. Most of the material has been collected within the framework of various research and monitoring projects carried out in Estonian nature reserves (1998-2009). A new type of trunk window trap, designed by the author in 2004 mainly for monitoring purposes, has been successfully used. 17 of the 85 species are new for the fauna of whole Baltic region: Pseudeuglenes pentatomus (Ths.) (Aderidae), Caenocara subglobosum (Muls. & Rey), Xyletinus tremulicola Y. Kangas (Anobiidae), Choragus sheppardi Kirby (Anthribidae), Cryptocephalus saliceti Zebe (Chrysomelidae), Dirrhagofarsus attenuatus (Mäklin), Hylis cariniceps (Rtt.), Microrhagus emyi (Rouget) (Eucnemidae), Gnathoncus communis (Marseul) (Histeridae), Notolaemus unifasciatus (Latr.) (Laemophloeidae), Agathidium discoideum Er. (Leiodidae), Anisoxya fuscula (Ill.) (Melandryidae), Mordellistena neuwaldeggiana (Pz.) (Mordellidae), Ripidius quadriceps Abeille de Perrin (Rhipiphoridae), Lissodema cursor (Gyll.) (Salpingidae), Aphodius quadrimaculatus (L.) (Scarabaeidae) and Eutheia schaumii Kiesw. (Scydmaenidae). One of the species, Caenocara subglobosum (Muls. & Rey) (Anobiidae), is new for the whole Northern Europe. Specimens of this species were collected from eastern and southern Estonia: most were caught in window traps but some also emerged from the collected fruiting bodies of Common Puffball (Lycoperdon perlatum). For 21 new species, Estonia lies on the northern edge of their range. Three of these, Triphyllus bicolor (F.), Mycetophagus ater (Rtt.) and Glischrochilus grandis (Tournier) that were collected from 6-10 sites, have a wider distribution in Estonia. Two species, Xyletinus tremulicola Y. Kangas (Anobiidae) and Stephanopachys linearis (Kug.) (Bostrichidae), have been listed on Annex II of the EU Habitats Directive. Two new species (Lymantor aceris (Lindemann) and Xyleborinus saxesenii (Ratz.)) were also added to the list of Estonian bark beetles (Curculionidae: Scolytinae).

A New Species

Ethiopia is known for its highly endemic and rich herpetofaunal diversity shaped by its biogeographical patterns. Here, a new species of skink, Trachylepis boehmei sp. nov., is described from the Ethiopian Highlands. It differs from its congeners in having smooth uncarinated dorsal scales, 26–29 scale rows around midbody, a slender body of small size, a relatively short tail, a low eye–snout distance and a unique colour pattern with 6–8 darkish brown dorsal stripes. Based on morphological characteristics, its biogeographical pattern and comparisons with other similar congeners this new species is closely related to Trachylepis megalura. A published new record of Trachylepis wingati for the Kafa region is re-examined and identified as T. megalura. An updated comprehensive key to the Trachylepis found in Ethiopia is provided. In the context of ongoing phylogenetic and taxonomic revisions of Trachylepis and its species complexes the presence of further cryptic taxa can be expected also for the Ethiopian biodiversity hotspots. Consequently, the need of further herpetological investigations in this region of ecological importance is stressed.

A New Species

The identification of Auricularia species has previously relied on the examination of macroscopic features of mushroom samples collected in Thailand. These features may vary with age, light exposure, moisture and other factors, making such identification prone to error. This study uses morphological characteristics and molecular data to improve upon previous classifications of Auricularia species. Fruiting bodies collected during recent field excursions and previous collections from herbaria were examined and sequenced for two loci, viz. ITS and rpb2. Auricularia asiatica is described as a new species based on both morphological characteristics and molecular data, and is introduced with a full description, illustrations and colour photographs. Auricularia cornea and A. villosula are described as new records from Thailand. A combined ITS and rpb2 phylogenetic tree is provided, showing the placement of five Auricularia species found in Thailand.

<p><em>Phytopythium</em> and <em>Pythium</em> species are known to be soil-born oomycete pathogens of forest trees in Europe. Little is known, however, about the presence of these micro-organisms in Polish oak forests. During the period 2007–2009 a comprehensive study of <em>Phytophthora</em> species in soils of oak forests in southern Poland was conducted using baiting technique. In this study, baits were also colonized by oomycete resembling <em>Pythium</em> species. Based on morphological characteristics and the ITS sequences comparisons, 10 species of <em>Phytopythium</em> and <em>Pythium</em> were isolated from the soil-root samples, including three putative new species belonging to the genus of <em>Phytopythium</em>. The most commonly encountered <em>Pythium</em> species was <em>Pythium anandrum</em>. The present study demonstrates for the first time that <em>Phytopythium citrinum</em> and <em>Pythium diclinum</em> can also act as soil-borne organisms in oak forests. In addition, these species were reported for the first time in Poland.</p>

A new mycoparasitic fungal species, Tuberculina photiniae sp. nov., is proposed based on morphological and molecular evidence. The species is characterized by its depressed hemispherical pale lilac to greyish purple sporodochia breaking through leaf surfaces, septated conidiophores with vinaceous lower parts and colourless upper parts, and the presence of colourless globose, subglobose or scarcely wide-ellipsoid conidia. Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analysis based on molecular data of ITS sequences showed that Tuberculina photiniae belongs to the Tuberculina-Helicobasidium clade and is closely related to H. longisporum and H. mompa. Further investigation was carried out for representative taxa in the Tuberculina-Helicobasidium group based on ITS+nLSU sequences in which the results demonstrated that the new species formed a monophyletic lineage and grouped with H. longisporum and H. mompa. Both morphological and molecular evidence confirmed the placement of the new species in the Tuberculina-Helicobasidium clade.

Species of Leptographium are anamorphs of Ophiostoma and best known as associates of tree-infesting bark beetles. The majority of these fungi and their insect associates are found on conifers where they typically cause sap-stain of lumber. A small number of species are also known as tree pathogens. Relatively few Leptographium species are found on angiosperm trees. Species described from these niches have increased in recent years. The objective of this study was to characterize a Leptographium species isolated from the roots of various hardwood trees in the southeastern United States. Morphology of this fungus differed from that of other Leptographium species. Comparisons of DNA sequences for part of the ITS2–28S ribosomal DNA region, the β-tubulin, and the elongation 1-α gene regions also showed that this fungus represents an undescribed taxon. The fungus is thus described as Leptographium profanum sp.nov.

A new wood-inhabiting fungal species, Scytinostroma yunnanense, is proposed based on morphological and molecular evidences. The species is characterized by an annual growth habit, resupinate basidiomata with cream hymenial surface, a monomitic hyphal system with generative hyphae bearing simple septa, fusiform to cylindrical cystidia and basidiospores (4.5–5.5 × 4.2–5.2 µm) are acyanophilous, subglobose to globose, hyaline, thin-walled, smooth, amyloid. The phylogenetic analyses based on molecular data of ITS sequences showed that the new species formed a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP) and then was sister to S. duriusculum.

White button mushroom, Agaricus bisporus (Lange) Imbach, is the most extensively cultivated and edible mushroom worldwide. The production of A. bisporus is commonly affected by wet bubble disease (WBD) imposing a significant economic burden in China. Although studies have shown that this disease is caused by fungi of Mycogone genus, the pathogen has not been fully characterized. In this study, 802 samples of diseased fruiting bodies of A. bisporus were collected from nine major mushroom-cultivating provinces in China, yielding a total of 586 Mycogone isolates. The morphological characteristics of these isolates were observed and compared, and multi-locus phylogenetic analyses (ITS, ACT, TEF1-α, TUB, RPB2, and LSU) were performed on the selected representative isolates. Three Mycogone species were identified: a new species M. xinjiangensis, M. perniciosa, and M. rosea. Mycogone rosea was the first-ever reported in China. Furthermore, M. rosea was found to be the most prevalent species (54.95% of all isolates) in all the sampled areas, except in Hubei and Xinjiang, followed by M. perniciosa (39.93%) and M. xinjiangensis (5.12%). Pathogenicity tests on the fruiting body and mushroom bed substantiated Koch’s postulates developing mildly different symptoms after inoculation with each species. This study, therefore, enhances our knowledge of the species associated with WBD in A. bisporus and provides useful insights for preventing WBD and allied diseases.

Abstract The genus Ceartocystiopsis includes ascomycetes fungi belonging to the Ophiostomatales that are not well recognized in the world. Described species so far have been found mainly in association with bark beetles in the Northern Hemisphere. The aims of this study were therefore to survey of distribution of species of Ceratocystiopsis associated with bark beetles infesting Picea abies and Pinus sylvestris in Norway. Adults for 22 different bark beetle species were collected from 13 stands in Norway. During this study, we recovered 126 isolates showing affinities to Ceratocystiopsis representing six species, including two described and four undescribed taxa. The four undescribed taxa collected during this work were characterised based on their morphological characteristics and multi-gene phylogenies. Herein, we describe these new species as Ceratocystiopsis chalcographii sp. nov., Ceratocystiopsis debeeria sp. nov., Ceratocystiopsis norroenii sp. nov. and Ceratocystiopsis troendelagii sp. nov. Ceratocystiopsis norroenii and C. rollhanseniana were the most frequently isolated species although the latter species had a much wider vector range. This study expands our knowledge about the taxonomy and species diversity of Ceratocystiopsis and beetle-fungus relationships.
