Sporobolomyces yuccicola,a new species of ballistosporous yeast equipped with ubiquinone-9

A hitherto undescribed ballistosporous yeast was isolated from a dead leaf of Yucca sp. in Canada. This yeast produces apiculate or short-ellipsoidal ballistospores, produces pale colored colonies, has Q-9 as the major ubiquinone, and does not contain xylose in the cells. This new yeast is described as Sporobolomyces yuccicola Nakase et Suzuki. Sporobolomyces yuccicola is the sixth species of the intermedius group, a group of atypical species of the genus Sporobolomyces equipped with Q-9.     

Four new species of yeast isolated from insect frass in bark ofTsuga heterophylla (Raf.) Sargent

Summary In a study of the yeasts associated with insect frass underneath the bark ofTsuga heterophylla (the Pacific Coast hemlock) four new species of yeast were found. These were described asSporobolomyces singularis, Bullera tsugae, Cryptococcus skinneri andCandida oregonensis. Sporobolomyces singularis is a non-pigmented species, which required an amendment of the genus definition. Ballistospore formation of the new species ofSporobolomyces and ofBullera was absent on malt agar and on potato glucose agar, but positive on corn meal agar. An unusual case of quantitative transgalactosylation by growing cells ofSporobolomyces singularis on lactose has been described. It has been proposed to establish a “Candida parapsilosis Group” of species to whichC. oregonensis was assigned.

Four new yeast species of the genus Sporobolomyces from plant leaves

Among the ballistoconidium-forming yeast strains isolated from various plant leaves collected in North and Northeast China, 12 strains forming orange to orange-red colored colonies were revealed to represent four novel species of the genus Sporobolomyces by conventional, chemotaxonomic and molecular phylogenetic studies, based on the 26S-rDNA D1/D2 domain and internal transcribed spacer (ITS) region sequences. Sporobolomyces beijingensis sp. nov., represented by eight strains (type strain CB 80T = AS 2.2365T = CBS 9730T), and Sporobolomyces jilinensis sp. nov., represented by two strains (type strain CB 118T = AS 2.2301T = CBS 9728T), clustered in the Johnsonii clade of the Sporidiobolus lineage. Sporobolomyces clavatus sp. nov., represented by strain CB 281T (= AS 2.2318T = CBS 9729T), belonged to the Agaricostilbum lineage and showed a close relationship to Sporobolomyces ruber and Sporobolomyces dracophylli. Sporobolomyces symmetricus sp. nov., represented by strain CB 64T(= AS 2.2299T = CBS 9727T), formed nearly symmetrical ballistoconidia and was closely related with Sporobolomyces vermiculatus and Sporobolomyces gracilis in the Gracilis clade of the Erythrobasidium lineage.     

Three new species of penicillium

Three new species of microfungi belonging to the genus Penicillium Link ex Fries are described and illustrated. All but one have been isolated from the atmosphere of las Palmas, capital city of the island of Gran Canaria (Canary Islands, Spain). They clearly differ from all species of the genus described so far and are, therefore, described and proposed as new species: Penicillium hispanicum sp. nov., Penicillium grancanariae sp. nov., and Penicillium palmensis sp. nov.     

Four new species of the genusSporobolomyces isolated from leaves in Thailand

Thirteen undescribed strains of ballistoconidium-forming yeasts, isolated from leaves collected in the suburbs and along the southeast seacoast of Bangkok, Thailand, were divided into four different groups in the genusSporobolomyces on the basis of morphological, physiological, biochemical, and chemotaxonomical characteristics, and analyses of the sequences of 18S rDNA and internal transcribed spacer regions. DNA-DNA reassociation experiments with related species revealed that these four groups were four new distinct species.Sporobolomyces nylandii sp. nov.,S. poonsookiae sp. nov.,S. blumeae sp. nov. andS. vermiculatus sp. nov. are proposed for these strains.     

Sporobolomyces inositophilus,a new species of ballistosporous yeast isolated from a dead leaf of Sasa sp. in Japan

A new species of ballistosporous yeast, Sporobolomyces inositophilus was isolated from a dead leaf of Sasa sp. collected at a mountain in Japan. This yeast is assumed to have a close relationship to Sporobolomyces singularis since it produces bilaterally symmetrical ballistospores and pale-coloured colonies and resembles Sporobolomyces singularis in these respects. These two species differ from typical species of Sporobolomyces and seem to constitute a natural taxonomic group.     

Filibryum (Hypnaceae), a new moss genus with a new species from East Asia

Filibryum, a new genus of the family Hypnaceae, is described to include three species from East Asia. Filibryum ogatae and F. yakoushimae are transferred to it from the genus Glossadelphus, while F. deguchianum is a newly described species. The genus is distinguished by the absence of a central strand in the stem, prorate leaf cells, and heteroblastic and deciduous stem leaves. Molecular data suggest that the genus is closely related to Taxiphyllum and the phylogenetic position of the new genus in the Hypnaceae is supported by an approximately unbiased (AU) test.     

Sporobolomyces diospyroris sp. nov., Sporobolomyces lophatheri sp. nov. and Sporobolomyces pyrrosiae sp. nov., three new species of ballistoconidium-forming yeasts in the Agaricostilbum lineage isolated from plants in Taiwan

Three strains of xylose-lacking and ubiquinone-10-having ballistoconidium-forming yeasts isolated from plant leaves collected in Taiwan were found to represent respective new species. In phylogenetic trees constructed based on the nucleotide sequences of 18S rDNA and D1/D2 domain of 26S rDNA, they were located in the Agaricostilbum lineage (Agaricostilbum/Bensingtonia cluster). Since the taxonomic properties of these species coincide with those of the genus Sporobolomyces, they are described as Sporobolomyces diospyroris sp. nov., Sporobolomyces lophatheri sp. nov. and Sporobolomyces pyrrosiae sp. nov., respectively.

It is distinguished from the closely allied R. lobatus in having radical leaves sub‐cordate with hairy lamina base and petiole hairy above; cauline leaves sessile, 3–7 lobed with linear to narrowly lanceolate lobes; sepals usually reddish brown, externally hairy; petals rounded‐obovate and oblong, receptacle glabrous except 1–3 hairs at the top.     

Sisyrinchium humahuacense of sect. Segetia a new species from Argentina

Abstract

A new species from the Andean region of northwestern Argentina is described and illustrated: Sisyrinchium humahuacense. This species can be distinguish from its closest related species by three main characters: the presence of a conspicuous horizontal rhizome, the colour of the flowers and the presence of rudimentary leaves not splitting in fibers. A phylogenetic analysis based on DNA sequences supported the inclusion of S. humahuacense within the genus and as part of the section Segetia. Also, a key to species to identify S. humahuacense is presented herein.     

Othonna cerarioides (Asteraceae: Othonnineae), a new species from Namaqualand,South Africa

Othonna cerarioides Magoswana and J.C. Manning is described as a new species from Namaqualand, Northern Cape Province of South Africa. It is an erect shrub with rod-like stems and branches, bearing numerous spur-shoots with obovate-oblanceolate leaves clustered at the tips, and up to nine disciform capitula per spur-shoot. Othonna cerarioides is anomalous in the genus in that the style of some of the disc florets is bifid. Othonna is diagnosed within subtribe Othonnineae by female-sterile disc florets with simple (or very rarely minutely bifid) styles. The disc florets in the closely related genus Hertia are bisexual with well branched styles.     

Centaurea amanosensis (Asteraceae), a new species from Turkey

Centaurea amanosensis M. Bona, a new species of Asteraceae from Hatay province of Turkey is described and illustrated. It is morphologically similar to C. cheirolopha (Fenzl) Wagenitz, C. lycopifolia Boiss. & Kotschy ex Boiss. & Kotschy, and C. stevenii Bieb. (Section Pseudoseridia), but it differs mainly in life form, general habit, leaves and achene characters. The IUCN conservation status of Critically Endangered (CR) should be applied to C. amanosensis.     

葡萄属一新名和一新种

描述了自甘肃南部发现的葡萄属一新种,文县蘡薁(Vitis wenxianensis W. T. Wang)。此新种与特产浙江的三出蘡薁[V. bryoniifolia Bunge var. ternata(W. T. Wang)C. L. Li]有很近的亲缘关系,二者可能是由蘡薁(V. bryoniifolia Bunge)衍生而出的一对姊妹群。基于上述认识,将三出蘡薁由变种提升至种的等级,但由于存在一个于1871年发表的种名(V. ternata Baker),因此,必须为三出蘡薁拟定一新名。
