Clavariadelphus species (Clavariadelphaceae, Gomphales) in China were examined using morphology, molecular phylogenetic analyses of ITS data and chemical reactions. Eleven taxa were identified in China, including four species known previously to occur in China (C. griseoclavus, C. ligula, C. sachalinensis and C. yunnanensis), two new record species from China (C. elongatus and C. himalayensis), four novel species (C. alpinus, C. amplus, C. gansuensis and C. khinganensis) and one species that could not be described due to the paucity of material. Finally, we also provided a taxonomic key for the identification of Clavariadelphus species in China.

ABSTRACT Yeasts from caves have rarely been examined. We examined yeasts collected from bat guano samples from 20 bat-inhabited limestone and volcanic caves located in 11 prefectures in Japan. Of ∼700 yeast-like colonies, nine Trichosporon species were recovered from 15 caves. Two of these were known species, and the remaining seven are potentially novel species, based on molecular phylogenetic analyses. In addition to Trichosporon species, identifiable strains of eight ascomycetous yeasts and one basidiomycetous yeast were recovered at frequencies of 5 to 35%. Our findings suggest that Trichosporon spp. are the major yeast species in bat guano in Japan and that bat guano is a potentially rich source of previously undescribed yeast species.

A novel species, Leucoagaricus fragilis, is described from the vicinity of the Cholistan desert, Punjab, Pakistan. The taxon is characterized by white, fragile basidiomata with a light brown, umbonate disk, a radially fibrillose pileus surface rarely splitting radially, pinkish brown lamellae at maturity, a white, bent stipe that stains yellowish upon handling, an inferior annulus, sub-globose to ellipsoid basidiospores, broadly clavate to abundantly sphaeropedunculate cheilocystidia, and cylindrical pileipellis hyphae intermixed with broader clavate elements with rounded ends. Morpho-anatomical and molecular phylogenetic analyses of nrITS and nrLSU datasets confirmed a new taxon in L. sect. Piloselli. A key to the known species of Leucoagaricus in Pakistan is also provided.

Powdery Mildew Fungi

Papaya (Carica papaya L.) is an important fruit crop in many tropical and subtropical countries. Powdery mildew commonly affects this host, causing premature leaf loss, reduced yields and poor fruit quality. At least fifteen different fungi have been identified as the causal agents of papaya powdery mildew. Powdery mildew symptoms were detected on potted papaya plants growing in two locations in Hungary. This study aimed to identify the causal agents. Morphology of powdery mildew samples was examined, and sequences of two loci were used for molecular taxonomic identifications. Only anamophs were detected in all samples, and four morphological types were distinguished. Most samples had Pseudoidium anamorphs, while some were of the Fibroidium anamorph. Based on morphology and molecular taxonomy, the Fibroidium anamorph  was identified as Podosphaera xanthii. The Pseudoidium anamorphs corresponded to three different Erysiphe species: E. cruciferarum, E. necator and an unidentified Erysiphe sp., for which molecular phylogenetic analyses showed it belonged to an unresolved species complex of E. malvae, E. heraclei and E. betae. Infectivity of P. xanthii and E. necator on papaya was verified with cross inoculations. A review of previous records of powdery mildew fungi infecting papaya is also provided. Podosphaera xanthii was known to infect, and E. cruciferarum was suspected to infect Carica papaya, while E. necator was recorded on this host only once previously. No powdery mildew fungus belonging to the E. malvae/E. heraclei/E. betae species complex is known to infect papaya or any other plants in the Caricaceae, so the unidentified Erysiphe sp. is a new record on papaya and the Caricaceae. This study indicates host range expansion of this powdery mildew fungus onto papaya.

Macadamia (Macadamia integrifolia) is endemic to eastern Australia and produces an edible nut that is widely cultivated in commercial orchards globally. A survey of fungi associated with the grey and green mold symptoms of macadamia flowers found mostly species of Botrytis (Sclerotiniaceae, Leotiomycetes) and Cladosporium (Cladosporiaceae, Dothideomycetes). These isolates included B. cinerea, C. cladosporioides, and unidentified isolates. Amongst the unidentified isolates, one novel species of Botrytis and three novel species of Cladosporium were delimited and characterized by molecular phylogenetic analyses. The new species are Botrytis macadamiae, Cladosporium devikae, C. macadamiae, and C. proteacearum.

Trees in the genusVachellia(previouslyAcacia) are commonly infected by the gall-inducing rustsRaveneliamacowanianaandR.evansii. Rust galls bearing aecial infections and relating uredinial and telial infections on the leaves of nineVachelliaspecies not previously recorded to be infected byRaveneliaspp. have recently been collected in South Africa. The rust fungi causing these infections were characterised using molecular phylogenetic analyses of DNA sequence data of the LSU and ITS rDNA regions as well as morphological examinations. The host range ofR.macowanianaandR.evansiiwas thus re-assessed and extended from four to nine species and from one to three species, respectively. Application of Principal Component Analyses (PCA) of telial morphological characters provided evidence of an effect of the host species on the teliospore morphology inR.evansii, but only minor effects inR.macowaniana. A novel gall-inducingRaveneliasp. closely related toR.macowaniana, was found onVachelliaxanthophloeaand it is described here asR.xanthophloeae.

Two hyphomycetous species were collected from leaves of Smilax china (Liliales, Smilacaceae) and Cremastra appendiculata (Asparagales, Orchidaceae). ITS barcoding indicated that they belong to the genus Zasmidium. Morphological data in combination with molecular phylogenetic analyses based on ITS, LSU and rpb2 confirmed that our Chinese strains represented a new species, Zasmidium liboense and a new record of Z. citri-griseum.

Species Grouping

The genus Berkheya is paraphyletic with the related genera Cullumia, Cuspidia, Didelta and Heterorhachis embedded within a broader clade termed the ‘Berkheya clade’. As a contribution towards reassessment of species relationships and delimitation of species groupings within the clade, the utility of external achene morphology for supporting natural species groups within the clade was evaluated. Achenes from 67 species and 10 infraspecific taxa were examined, including representatives of each genus currently recognised in the Berkheya clade. Achene pubescence and pappus characteristics (e.g., scale shape and number of scales within a series) were indicated to be particularly variable and thus less reliable for assessment of species relationships. Of the currently recognised genera, only segregation of Cullumia was supported by achene and pappus characteristics. Species groupings implicit in Roessler’s infrageneric classification of eight series within Berkheya were to a large extent supported. However, in particular, series Speciosae was indicated to be a disparate species grouping and the distinction of series Angustae and Cruciatae is not supported by achene and pappus morphology. Achene and pappus characteristics suggest several novel species groupings (e.g. an affinity between Berkheya cuneata, B. ferox and B. spinosa). Although the taxonomic sampling in published molecular phylogenetic analyses is limited, achene and pappus morphology partially supports clades resolved in prevailing phylogenetic reconstructions for the clade. More complete sampling in future molecular phylogenetic analyses is required to test novel species affinities suggested in the present study and to explore the evolution of the achene and pappus in the Berkheya clade.

SUMMARYFive novel species,Auerbachia scomberoidin. sp.,Auerbachia chaetodonin. sp.,Auerbachia caranxin. sp.,Coccomyxa colurodontidisn. sp. andCoccomyxa gobiodonin. sp. are described from the gall bladders of marine teleosts. These species descriptions provide the first record ofAuerbachiafrom Australian waters. Each species is characterized morphologically, including additional measurements forAuerbachiaspp. and small subunit ribosomal DNA (SSU rDNA) sequences were determined for molecular phylogenetic analyses. All 5 species were each recovered from a single (and different) species of host. Phylogenetic analyses revealed a close genetic relatedness between members ofAuerbachiaandCoccomyxa. Based on these phylogenetic data, on obvious paraphyly displayed by the Myxidiidae and on priority, we propose the re-establishment of the family Coccomyxidae to house all species of the genera,Coccomyxa,AuerbachiaandGlobospora.
