Résumé :

A new isoquinoline alkaloid, ampullosine (3-methyl-isoquinoline-6-carboxylic acid, 1), was isolated from Sepedonium ampullosporum and characterized by spectroscopic analysis and chemical reactions. This compound is responsible for the deep yellow color of the culture fluid of this species. Moreover, the known compounds sepedonin (2) and anhydrosepedonin (3) were detected. Twelve strains belonging to eight species of Sepedonium have been screened for these three metabolites by LC/ESI-SRM (selected reaction monitoring). Ampullosine (1) could be detected in almost all species in Sepedonium, but n

Résumé :

Four new 19-residue peptaibols, named tulasporins A–D (1–4), were isolated from the semi-solid cultures of Sepedonium tulasneanum. Their structures were elucidated on the basis of extensive ESI-HRMSn fragmentation studies as well as 1H NMR spectroscopic analyses. Interestingly, the structures of tulasporins A–D (1–4) resemble those of chrysospermins isolated earlier from cultures of S. chrysospermum. Previously, it was hypothesized that the peptaibol production by Sepedonium species correlates with the morphology of the aleurioconidia, as exclusively round-shaped aleurioconidia forming species

Résumé :

We present the first major survey of regional diversity, distribution and host-association of Sepedonium. Whereas the rather scarce worldwide records of this mycoparasitic fungus suggested no specific distribution pattern of most species before, we provide new evidence of endemic and specific host-parasite guilds of Sepedonium in Southern South America, including the description of a new species. The corresponding inventory was performed in temperate central Chile. The regional landscape, a mosaic of exotic timber plantations and remnants of native Nothofagus forests, facilitates a unique comb

Résumé :

During an investigation of fungicolous fungi associated with mushrooms in China, four boleticolous fungi were collected from Sichuan Province. Based on the morphological features and multi-gene phylogenetic analyses this study introduces two new species, Hypomyces ampullaris, and H. sichuanensis. The new species are described and illustrated comprehensively and compared with their related fungi. Hypomyces ampullaris is similar to Sepedonium ampullosporum in forming candelabrum-like conidiophores and producing ampulliform conidia but differs from the latter in having shorter phialides and small

Résumé :

The lamellate boletes found in the Cooloola Sand-mass, Queensland are described and discussed in the light of earlier Australian records of paxilloid fungi. Nine species of Paxillus are discussed, two in Tapinella, which is maintained as a separate entity, and 11 are assigned to Phylloporus. Of the last, eight are new records to Australia and two are new species. Three appendices cover various aspects of studies on Australian boletes which have come to light since the publication of this series, including notes on the host-range of the parasitic hyphomycete Sepedonium.

Résumé :

Fungal species of genus Sepedonium are rich sources of diverse secondary metabolites (e.g., alkaloids, peptaibols), which exhibit variable biological activities. Herein, two new peptaibols, named ampullosporin F (1) and ampullosporin G (2), together with five known compounds, ampullosporin A (3), peptaibolin (4), chrysosporide (5), c(Trp-Ser) (6) and c(Trp-Ala) (7), have been isolated from the culture of Sepedonium ampullosporum Damon strain KSH534. The structures of 1 and 2 were elucidated based on ESI-HRMSn experiments and intense 1D and 2D NMR analyses. The sequence of ampullosporin F (1) w
