Two endoconidial, black meristematic fungi, Celosporium larixicolum gen. et sp. nov. (Dothideales) and Hispidoconidioma alpina gen. et sp. nov. (Capnodiales) are described from black subicula on twigs of declining larch ( Larix lyallii Parl) trees in Alberta, Canada. Conidioma morphology and phylogenetic analysis of LSU and ITS regions indicate that these taxa are both distinct from each other and from previously described endoconidial genera. Conidiomata of C. larixicolum consist of black cellular clumps (aggregated conidiogenous cells) that are either naked or enveloped by scant to dense mycelium that sometimes organizes into a cupulate peridium. Endoconidia are 1–3 celled, hyaline when released but become pigmented as they age, and very variable in size and shape, e.g., globose, pear-shaped, osteoid, or discoid with an irregular flange. In H. alpina, colonies are three-layered, consisting of a central pseudoparenchymatous layer sandwiched between an upper and a basal hyphal layers, and conidiogenesis occurs in sporadic areas of the central layer. Endoconidia are unicellular, hyaline, and subglobose to ellipsoid. The strong phylogenetic affinities between these newly described taxa and slow-growing, melanized fungi isolated from rocks suggest individual black meristematic fungus lineages may have broad habitat ranges.

A New Species

A new polypore, Ceriporia albomellea, collected from tropical China, is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by thin, resupinate basidiome with a white subiculum, cottony margin, white to cinnamon-buff pores, clavate cystidia and oblong-ellipsoid basidiospores measured as 3.1–3.8 × 1.7–2 µm. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions supported C. albomellea as a distinctive species belonging to Ceriporia.

A New Species

Members of the tubicolous polychaete family Serpulidae constitute one of the most important groups of marine fouling biota. This paper describes a new species of the serpulid genusHydroidesfrom dock fouling at Mazatlán (southern Gulf of California), providing information about live colouration and reproductive features.Hydroides dolabrussp. nov. belongs to a subgroup of species in which verticil spines are equal in size and shape, lack both external and lateral spinules, but have various modifications to their tips. However,Hydroides dolabrussp. nov. is distinct in having tips of verticil spines pickaxe-shaped, with asymmetrical triangular radially orientated projections: the internal projections are short and point inward the verticil centre, while longer external projections point outward the verticil centre. Like all species of the genus,H. dolabrussp. nov. is a gonochoristic broadcast spawner lacking sexual dimorphism. A phylogenetic analysis of Hydroides based on COI, 18S and cytbsequence data reveals thatH. dolabrussp. nov. is genetically distinct from other species ofHydroidesfor which sequence data are available. The new species is the 11th in the genus described from Mexican waters.

One of the major problems hindering the systematic study of tachinid flies is that genera are often poorly defined, making it difficult to unambiguously assign species among closely related genera. Within the tribe Winthemiini, an example of this problem is represented by the unstable classification of the Afrotropical species most recently classified as Smidtia capensis (Schiner). This species has been previously assigned to four different genera on the basis of limited examination and evidence. Here, we evaluate the identity and phylogenetic affinities of this species and other members of the tribe Winthemiini using morphological and molecular phylogenetic analysis. We demonstrate that S. capensis actually belongs to the genus Winthemia Robineau-Desvoidy. We also find that Winthemia is paraphyletic with respect to two monotypic genera, Crypsina (type species Crypsina prima Brauer & Bergenstamm) and Hemiwinthemia (type species Hemiwinthemia calva Villeneuve). On the basis of morphological and genetic evidence, we propose to extend the generic limits of Winthemia to include W. londti, sp. nov. (South Africa), W. capensis (Schiner), comb. nov. (South Africa), W. prima (Brauer & Bergenstamm), comb. nov. (China, Japan, Australia) and W. calva (Villeneuve), comb. nov. (D.R. Congo), thus synonymising with Winthemia the generic names Crypsina, syn. nov. and Hemiwinthemia, syn. nov.

The 16S rRNA gene sequences for 34 strains, including 11 isolates, were determined to classify scab-causing Streptomyces spp. and relatives isolated from potato scab lesions collected in Jeju, Korea. The 16S–23S rDNA internally transcribed spacer (ITS) sequences were determined to investigate whether the 16S–23S ITS region is useful for analysing intra- and interspecific relationships in these bacteria. On the basis of phylogenetic analysis of 16S rRNA gene sequences, most of the isolates were classified as Streptomyces scabiei and Streptomyces acidiscabies. Isolate KJO61 was placed in an ambiguous taxonomic position between Streptomyces reticuliscabiei and Streptomyces turgidiscabies. 16S–23S ITS region sequence analysis showed that tRNA genes were not found in this region of Streptomyces spp. The 16S–23S ITS regions of Streptomyces spp. exhibited various lengths and highly variable sequence similarities (35–100 %) within strains as well as intra- and interspecies. It was revealed that Streptomyces europaeiscabiei could be clearly differentiated from Streptomyces scabiei. However, it was clarified that ITS regions are not useful in phylogenetic analysis of Streptomyces spp.

A New Species

A new species of Cortinarius sect. Calochroi, C. lentus, is described on the basis of morphological and genetic features. It is characterised by a yellow-orange to brown-orange pileus, initially violaceous pink lamellae, a cream to pale yellow universal veil, amygdaliform to almost citriform spores, coarsely verrucose, typically narrow (Qav = 1.9) and habitat preference for chestnut woods on acidophilic soil. It is compared with the closest species from a morphological point of view, in particular with C. leochrous and C. calochrous. In order to assess its relative position within Calochroi, a phylogenetic approach based on RPB1 and ITS regions was performed. The ITS phylogenetic analysis did not resolve the position of C. lentus within sect Calochroi, but in our RPB1 phylogenetic analysis, C. sublilacinopes is closely related.

A new polypore, Daedalea americana, collected from North and Central America, is described and illustrated based on morphological characters and molecular evidence. It is characterized by annual and pileate basidiocarps, grayish brown with brown to cinnamon brown band and concentrically zonate pileal surface when fresh, cream to clay-pink pore surface, circular to angular pores (4–5 per mm) and ellipsoid basidiospores measured as 4.0–5.1 × 2.1–3.0 µm. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions support D. americana as a distinctive species belonging to Daedalea.

Lamprospora sylvatica is described as a new species based on finds from Ukraine, Slovakia, Germany and Norway. It is characterised by the combination of the following features: pinkish, orange to reddish-orange apothecia with a fimbriate margin, globose ascospores with more or less regular areolate ornamentation, infecting strong rhizoids of Dicranum montanum with an infectious structure consisting of a one-celled appressorium surrounded by a multi-layered cluster of thick-walled cells and haustorium within the rhizoids. The apothecia were always found on rotten wood, which is an unusual habitat for hosts of bryophilous Pezizales. The new species is compared to similar taxa morphologically and by means of DNA sequencing. In the phylogenetic analysis based on LSU and ITS regions, L. sylvatica forms a well-supported clade close to L. feurichiana (on Ceratodon purpureus), L. kristiansenii (also on C. purpureus) and L. campylopodis (on Campylopus spp.).

Chromoblastomycosis is a chronic human melanized fungi infection of the subcutaneous tissue caused by traumatic inoculation of a specific group of dematiaceous fungi through the skin, often found in barefooted agricultural workers, in tropical and subtropical climate countries. We report the case of a male patient presenting a slow-growing pruriginous lesion on the limbs for 20 years, mistreated over that time, which was diagnosed and successfully treated as chromoblastomycosis. Besides the prevalence of this disease, treatment is still a clinical challenge.

A new species of Polyporales, named as Skeletocutis yunnanensis, was collected on angiosperm wood in northern Yunnan Province, southwestern China. It is described based on morphological characteristics and molecular evidence. The species belongs to the Skeletocutis subincarnata complex, but differs morphologically from all known species of the genus by white, cream to buff pores surface, angular pores mostly 5–6 per mm with entire mouths, a dimitic hyphal structure both in trama and subiculum, generative hyphae in whole basidiocarps covered by fine crystals, skeletal hyphae unchanged in KOH, not agglutinated, allantoid basidiospores measured as 3.5–4.5 × 1.0–1.2 µm, and growth on angiosperm wood. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions indicated that the new species grouped with Skeletocutis and nested in the tyromyces clade.

AbstractLecanora demissa (Körb.) Zahlbr. is a crustose, lobate lichen that produces soredia and conidiomata but no apothecia. Its placement in Lecanora has long been questioned but nothing better has been proposed. We have studied the nuclear rDNA of the ITS regions and the SSU of L. demissa. In an alignment of the ITS regions of several representatives of Lecanora s. lat. it could clearly be shown by a PAUP analysis, using Aspicilia caesiocinerea as outgroup, that L. demissa does not belong to Lecanora. In a PAUP analysis of sequences of the SSU from representatives of the order Lecanorales, using members of Saccharomycetales as outgroup, L. demissa clustered on a well-supported branch with Caloplaca chlorina. In a further analysis of the ITS sequences of L. demissa together with representatives of Caloplaca and Xanthoria using Protoparmelia as outgroup two most parsimonious trees were found. In these trees the L. demissa branch was well within a strongly supported clade with C. cerina, the type species of the genus Caloplaca. The sister taxon to L. demissa in this analysis was C. variabilis. Chemical data and characters of the conidiomata support the affinity with Caloplaca and the new combination C. demissa (Körb.) Arup & Grube is therefore proposed. A lectotype for Imbricaria demissa has been designated. The phylogenetic analysis of several representatives of the genera Caloplaca and Xanthoria suggests that these genera are not monophyletic as presently circumscribed. Two large, monophyletic groups of species could be recognized, one with Xanthoria species mixed with lobate and crustose members of Caloplaca, and one with mainly crustose Caloplaca, including both species with orange or black apothecia.
