A new genus Siepmannia of the Mucoraceae family is described. Siepmannia pineti sp. nov.

Peptaibiomics: Screening for polypeptide antibiotics (peptaibiotics) from plant-protective Trichoderma species.

Eight strains of Trichoderma species (T. strigosum, T. erinaceus, T.

Fungal endophytes in potato roots studied by traditional isolation and cultivation-independent DNA-based methods.

The composition and relative abundance of endophytic fungi in roots of field-grown transgenic T4-lysozyme producing potatoes and the parental line were assessed by classical isolation from root segments and cultivation-independent techniques to test the hypothesis that endophytic fungi are affected by T4-lysozyme. Fungi were isolated from the majority of root segments of both lines and at least 63 morphological groups were obtained with Verticillium dahliae, Cylindrocarpon destructans, Colletotrichum coccodes and Plectosporium tabacinum as the most frequently isolated species. Dominant bands in the fungal fingerprints obtained by denaturing gradient gel electrophoresis analysis of 18S rRNA gene fragments amplified from total community DNA corresponded to the electrophoretic mobility of the 18S rRNA gene fragments of the three most abundant fungal isolates, V.

Trichoderma brevicompactum complex: Rich source of novel and recurrent plant-protective polypeptide antibiotics (peptaibiotics).

Three strains of Trichoderma brevicompactum and another four that are closely related to that species (Trichoderma cf. brevicompactum) were analyzed for the formation of polypeptide antibiotics (peptaibiotics) by LC/ESI-MS(n). These isolates were selected because of an antagonistic potential against Eutypa dieback and Esca disease of grapevine and have not yet been investigated for the production of peptide antibiotics.

Delimitation of Penicillium virgatum sp. nov. and P. daleae on the basis of morphological and molecular characters.

Penicillium virgatum sp. nov. is described from the soil of a soybean field in New Caledonia.

Fusarium langsethiae sp. nov. on cereals in Europe.

A new species of Fusarium, Fusarium langsethiae, is described, illustrated and discussed. This species is isolated from kernels of oats, wheat and barley in several European countries. Morphologically, the species resembles Fusarium poae.

Fusarium commune is a new species identified by morphological and molecular phylogenetic data.

Fusarium commune sp. nov. was isolated from soil and Pisum sativum in Denmark and several widespread locations within the northern hemisphere from diverse substrates including white pine, Douglas fir, carnation, corn, carrot, barley and soil.

Description of Colletotrichum lupini comb. nov. in modern terms.

Gloeosporium lupini Bondar is transferred to Colletotrichum. The fungus is characterized morphologically and illustrated. The two varieties, Colletotrichum lupini (Bondar) Nirenberg, Feiler & Hagedorn, comb.
