Two new species of <Emphasis Type="Italic">Lirula</Emphasis> on <Emphasis Type="Italic">Abies</Emphasis> from Japan

Two new species of Lirula (L. japonica and L. exigua) on Abies mariesii collected in subalpine areas of northern Japan are described as members of Rhytismatales, Discomycetes. Lirula japonica causes needle cast in fir, but L. exigua seems to occur on the needles of physically damaged twigs. Morphological characteristics of both species are discussed.     

The rust fungi of <Emphasis Type="Italic">Luzuriaga</Emphasis> (Luzuriagaceae) with description of a new species, <Emphasis Type="Italic">Puccinia luzuriagae-polyphyllae</Emphasis>

Three species of rust fungi (Uredinales), Puccinia perforans, P. fuegiana (= Uromyces skottsbergii), and Aecidium callixenis have been described on members of Luzuriaga (Luzuriagaceae). Puccinia luzuriagae-polyphyllae is added as a new species on Luzuriaga polyphylla from Chile. The rust had been confused hitherto with P. perforans occurring on L. radicans. Both species differ from P. fuegiana on L. marginata by the absence of a uredinial state and several telial characters. The investigated collections of Puccinia species on Luzuriaga indicate that each is restricted to a single host species. A determination key is presented.

A new species of <Emphasis Type="Italic">Gymnopilus</Emphasis> Sect. <Emphasis Type="Italic">Microspori</Emphasis> from Japan

Gymnopilus ombrophilus sp. nov., growing on rotten wood of conifers and hardwoods from Niigata, Japan is described and illustrated. It is characterized by its medium-sized, brownish-orange basidiocarps with a finely squamulose pileus, stipe lacking an annulus, and mild taste, and microscopically by dextrinoid, small, broadly ellipsoid basidiospores. The new species belongs to the section Microspori. The differences between the taxon and similar species are briefly discussed.     

A new species of <Emphasis Type="Italic">Cortinarius</Emphasis> sect. <Emphasis Type="Italic">Orellani</Emphasis> from Japan

Cortinarius breviradicatus sp. nov., found in deciduous forests, is described and illustrated from Niigata, Japan. It is characterized by its medium-sized to large dark brown basidiocarp, acutely conical pileus, and rooting stipe, and by subglobose to broadly ellipsoid basidiospores. In addition, the extracting solution from its basidiocarps exhibits a strong fluorescence around 400–430 nm in ultraviolet radiation (250 nm), which was observed in a species of Cortinarius sect. Orellani. The new species belongs to the section Orellani. The differences between the new taxon and similar species are briefly discussed.     

Four new species of <Emphasis Type="Italic">Phyllosticta</Emphasis>, one new species of <Emphasis Type="Italic">Pseudocercospora</Emphasis>, and one new combination in <Emphasis Type="Italic">Passalora</Emphasis> from Japan

During a survey of plant-inhabiting fungi in a botanical garden in Japan, some noteworthy fungi were collected from leaf spots of some herbal and arboreal plants. Among them, five new species are described, namely: Phyllosticta. ardisiicola on Ardisia crenata, Phy. aspidistricola on Aspidistra elatior, Phy. kerriae on Kerria japonica, Phy. fallopiae on Fallopia japonica, and Pseudocercospora davidiicola on Davidia involucrata. Passalora pyrrosiae, a new combination for Pseudocercospora pyrrosiae on Pyrrosia lingua, is proposed based on its morphological characteristics designating the neotype specimen.     

<Emphasis Type="Italic">Puccinia calystegiae-soldanellae</Emphasis>, a new rust species on <Emphasis Type="Italic">Calystegia soldanella</Emphasis> from Japan

A rust species on Calystegia soldanella in Japan has been treated as Puccinia convolvuli to date. However, morphological characteristics of specimens on C. soldanella collected from Japan are significantly different from those of specimens on other Calystegia and Convolvulus species from different areas of the world. It is proved by inoculation experiment that the rust on C. soldanella is specific to C. soldanella. Based on these results, Puccinia rust on C. soldanella from Japan is described as a new species, Puccinia calystegiae-soldanellae.     

<Emphasis Type="Italic">Linaria khalkhalensis</Emphasis> (<Emphasis Type="Italic">Linaria</Emphasis> sect. <Emphasis Type="Italic">Linaria</Emphasis>, Scrophulariaceae), a new species from Iran

Summary   Linaria khalkhalensis Hamdi & Assadi is described as a new species from Azerbaijan and Guilan provinces (northern Iran), belonging to Linaria sect. Linaria. It is close to Linaria lineolata Boiss. and L. elymaitica (Boiss.) Kuprian., which it resembles in habit and vegetative features. However, floral and seed characters together with a distinctive geographical distribution, warrant recognition at the species rank. An illustration of the new species, a distribution map, scanning electron micrographs of seed and capsule surfaces, and an identification key are also included.

Comparative phylogeography of capitulate <Emphasis Type="Italic">Campanula</Emphasis> species from the Balkans,with description of a new species, <Emphasis Type="Italic">C. daucoides</Emphasis>

Capitulate inflorescence is a specific, strongly adaptive and rare feature in the genus Campanula. We studied morphologically eight capitulate Campanula taxa from the Balkans (1537 individuals/52 populations) and one more species from Caucasus at the molecular level (using chloroplast markers trnG^UCC-trnS^GCU and psbA-trnH, 130 individuals/58 populations) to assess their relations and evolutionary histories. Although all studied taxa were well circumscribed at both the morphological and molecular levels (except morphologically distinct but genetically invariable C. moesiaca which acquired its single haplotype via past cytoplasmic introgression from C. cervicaria), their relations inferred from the two datasets were incongruent possibly due to the homoplasy of morphological characters frequently reported in Campanula. Interspecific hybridization and introgression affected majority of studied species and may be more common in Campanula than previously thought. These processes, along with incomplete lineage sorting and retention of ancestral polymorphisms, hampered our phylogenetic reconstructions and prevented us to fully resolve species relations, and to support monophyletic origin of capitulate Campanula species. Nonetheless, several cryptic taxa were delineated, and C. daucoides was described as a new capitulate Campanula species. Different evolutionary histories and multiple glacial refugia were inferred for all species represented by multiple samples (except C. moesiaca). According to our dating, their speciation was in most cases triggered by various geo-historic events such as the uplift of the Alpide belt, Messinian Salinity Crisis, or desiccation of the Pannonian Sea/Pliocene Lakes from the central Balkans, while their further diversification was mainly driven by the onset of the Quaternary and cycles of glacials/interglacials.     

<Emphasis Type="Italic">Metarhizium bibionidarum</Emphasis> and <Emphasis Type="Italic">M. purpureogenum</Emphasis>: new species from Japan

Two new species of Metarhizium, M. bibionidarum and M. purpureogenum are described from Japan. Metarhizium bibionidarum is the phylogenetic sister species of M. pemphigi and a member of the M. flavoviride species complex. It is distinguished morphologically from M. pemphigi by its larger conidia. The species is based on a collection of an infected March fly larva (Diptera: Bibionidae) but is also known to occur on fruit beetle (Coleoptera: Scarabaeidae) encountered in France. Metarhizium purpureogenum was isolated from soil by plating and insect baiting methods and represents a unique phylogenetic lineage placed outside the M. anisopliae and M. flavoviride species complexes. Three isolates of M. purpureogenum excreted a distinctive red-purple pigment into agar medium when co-cultured with M. robertsii or Aspergillus oryzae.     

Three new <Emphasis Type="Italic">Ophiostoma</Emphasis> species with <Emphasis Type="Italic">Pesotum</Emphasis> anamorphs associated with bark beetles infesting <Emphasis Type="Italic">Abies</Emphasis> species in Nikko,Japan

Three species of Ophiostoma possessing Pesotum anamorphs isolated from bark beetles and their galleries infesting Abies species in Nikko, Japan, are described as new species. Ophiostoma nikkoense is characterized by brush-shaped synnemata producing long septate clavate conidia, perithecia with neck, and allantoid ascospores. Ophiostoma microcarpum has smaller perithecia with hyphoid ostiolar hyphae on the neck, and the ascospores are cylindrical or ossiform in side and face views. Ophiostoma abieticola has perithecia without ostiolar hyphae on the neck and produces orange-section-shaped or reniform ascospores.Contribution no. 187, Laboratory of Plant Parasitic Mycology, Institute of Agriculture and Forestry, University of Tsukuba

Summary   Bulbophyllum fendlerianum is newly described based on a collection of August Fendler in Venezuela, deposited at the Royal Botanic Gardens, Kew. It was previously confused with B. manarae, but differs significantly from the latter species in its petal and lip shape, particularly the callus.     

A new <Emphasis Type="Italic">Dactylella</Emphasis> species from <Emphasis Type="Italic">Orbilia alba</Emphasis>

A new Dactylella species, Dactylella alba was isolated from the ascospores of Orbilia alba collected in Wenshan County, Yunnan Province, China. Conidiophores were either not branched or occasionally branched, bearing divergent sterigmata on the tip with single conidium on each. Conidia were elongated ellipsoids, 1–2 septate, mostly 1 septate. By combining the ITS sequence with morphological characteristics, a new anamorphic species is described and illustrated together with its teleomorph.
