Trichoderma (Ascomycetes, Hypocreales) strains that have warted conidia are traditionally identified as T. viride, the type species of Trichoderma. However, two morphologically distinct types of conidial warts (I and II) have been found. Because each type corresponds to a unique mitochondrial DNA pattern, it has been questioned whether T. viride comprises(More)
ABSTRACT Fusarium wilt of cotton is a serious fungal disease responsible for significant yield losses throughout the world. Evolution of the causal organism Fusarium oxysporum f. sp. vasinfectum, including the eight races described for this specialized form, was studied using multigene genealogies. Partial sequences of translation elongation factor(More)
Gloeosporium lupini Bondar is transferred to Colletotrichum. The fungus is characterized morphologically and illustrated. The two varieties, Colletotrichum lupini (Bondar) Nirenberg, Feiler & Hagedorn, comb. nov. var. lupini and Colletotrichum lupini var. setosum Nirenberg, Feiler & Hagedorn var. nov. are described. They are compared with additional(More)
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. It is differentiated from F. poae by slower growth, less aerial mycelium and absence of odour; its napiform or globose(More)
A new Phytophthora hybrid of Ph. cactorum (Leb. & Cohn) Schroet. and Ph. nicotianaevan Breda de Haan pathogenic to cultivars of Pelargonium grandiflorum hort. is described as Phytophthora X pelgrandis and its morphological features are documented. Morphological, physiological (e.g., temperature requirements) and molecular data (DNA sequencing, random(More)
An integrated systematic study was carried out to clarify the taxonomical position and relationship of Fusarium langsethiae to other taxa within the Fusarium section Sporotrichiella. Strains of this species were compared with strains of the closely related species Fusarium poae and Fusarium sporotrichioides using a composite dataset. This set consisted of(More)
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(More)
Penicillium virgatum sp. nov. is described from the soil of a soybean field in New Caledonia. Its delimitation from P. daleae, isolated from forest soils in Poland and Germany, is discussed. The species are differentiated on the basis of morphological features of their cultures in vitro, comparison of the PCR-RFLP profiles with DdeI, HpaII, Sau3A1, and TagI(More)
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. Fusarium commune is characterized by and distinguished from its putative sister taxon, the F. oxysporum complex, in(More)
More than 600Fusarium strains were screened for their ability to produce moniliformin in vitro. They represented 90 species and 15 sections (without sectionPseudomicrocera). A simple TLC-method (agar plug method) was tested for its applicability to detect moniliformin in fungal cultures. It revealed moniliformin production in 146 strains representing 32(More)
