梗孢酵母属的一个新种

作者于1978年从福建省福州市西湖公园的芒果花中分离出一株酵母1519。该菌株不产生子囊孢子、掷孢子,亦未见到有锁状连合。未发现有性繁殖。无性繁殖是在母细胞上产生小梗,小梗上产生子细胞,子细胞还可再生小梗再生子细胞。如果子细胞不脱落则成链状或分枝的链状。不发酵任何糖。按照形态和繁殖特征只符合Lodder(1970)酵母分类专著中半知菌部分的梗孢酵母。因此将它放入梗孢酵母属,命名为福州梗孢酵母(Sterigmatomyces fuzhouensis sp.n.)。

Molecular and morphological data reveal two new species of Scolecobasidium

Two species of Scolecobasidium were isolated from soil in Hainan and Hebei Provinces, China. The two taxa develop broadly ellipsoid conidia and ellipsoidal to oblong conidia, respectively. Their taxonomic placement in Scolecobasidium was confirmed by morphological similarity and phylogenetic analysis of the RNA polymerase II subunit b (RPB2) sequence data. The two fungi, which are morphologically distinct to previously described species, and occupy unique positions in the phylogenetic tree, are thus introduced as the new species Scolecobasidium terricola and S. ellipsoideum. They are described and illustrated and compared with similar species in the genus.

A new species of Scolecobasidium associated with the sooty blotch and flyspeck complex on banana from China

Sooty blotch and flyspeck is caused by a complex of epiphytic fungi on diverse hosts. A fungus morphologically similar to Scolecobasidium humicola was isolated from a banana fruit exhibiting SBFS signs in Hainan, China. ITS and LSU sequences of rDNA corroborated that it was a Scolecobasidium species. The results of LSU rDNA analysis support the interpretation that Ochroconis is synonymous with Scolecobasidium. Five new combinations, S. anomalum, S. calidifluminale, S. gallopavum, S. gamsii, and S. lascauxense, were proposed. A new species, S. musae, was described based on morphological characteristics and sequence comparison with previous species.

Two new species of Rhynchosporium

Rhynchosporium consists of two species, R. secalis and R. orthosporum. Both are pathogens of grasses with R. secalis infecting a variety of Poaceae hosts and R. orthosporum infecting Dactylis glomerata. Phylogenetic analyses of multilocus DNA sequence data on R. secalis isolates originating from cultivated barley, rye, triticale and other grasses, including Agropyron spp., Bromus diandrus and Hordeum spp., resolved the monophyletic groups into three species according to their respective hosts. Host specificity according to phylogenetic lineages was confirmed with pathogenicity studies. Because R. secalis was described first on rye this name is retained for Rhynchosporium isolates infecting rye and triticale. Rhynchosporium isolates infecting cultivated barley and other Hordeum spp. and Bromus diandrus belong to a distinct species, R. commune. Similarly isolates infecting Agropyron spp. represent a distinct species of Rhynchosporium, namely R. agropyri. A PCR-RFLP assay was developed as a rapid tool for species identification of R. secalis and R. commune.     

Two new species of Cladorrhinum

Two new species of Cladorrhinum, C. flexuosum and C. microsclerotigenum, are described and their sequences of the 5.8S and 28S ribosomal DNA and internal transcribed spacers 1 and 2 of the ribosomal RNA gene cluster analyzed. Cladorrhinum flexuosum, isolated from soil in Spain, forms fast-growing, dull yellow colonies, flexuous conidiophores and globose to dacryoid conidia. Cladorrhinum microsclerotigenum, isolated from Musa sp. in Turkey, strongly resembles Cladorrhinum phialophoroides in the production of abundant terminal phialides, ellipsoid conidia and microsclerotia in culture. It differs from C. phialophoroides in its ability to grow at 36 C and high number of intercalary phialides, which only infrequently occur in C. phialophoroides.
