Ceratocystis coerulescens RWD 451 (Ascomycetes) was cultivated on defined synthetic culture medium containing glucose (3.0% ), asparagine (0.1% ), mineral salts and thiamine. 6 weeks oid cultures produced methyl heptenyl compounds, citronellol. citronellyl acetate, dihydro-farnesol and a hitherto unknown monoterpene alcohol. By GC/MS, 'H and l3C NMR spectroscopy, this alcohol could be identifie...

Sand buried wood materials were collected from the beaches of Kerala, Tamil Nadu and Pondicherry and screened for marine fungi. A total of 27 arenicolous marine fungi were encountered including 19 Ascomycetes, 1 Basidiomycete and 7 Mitosporic fungi. The present study records the maximum number of arenicolous marine fungi reported so far. Ceriosporopsis capillacea, Dryosphaera tropicalis and Sav...

Two new ascomycetes, Boerlagiomyces costaricensis (Pleosporales) and Scopinella musciformis (Sordariales sensu lato), from litter samples collected in rainforests of Costa Rica, are described and illustrated. Boerlagiomyces costaricensis has globose, ostiolate ascomata covered by numerous setae-like hairs; cylindrical, fissitunicate asci without apical structures; and large, fusiform, muriform,...

Substrate specificity tests were used to identify the presence of laccase in two strains of Leptosphaerulina briosiana (Poll.) Graham and Luttrell, an ascomycete which causes leaf spot in alfalfa. Cytochemical localization of monophenol monooxygenase (laccase) as well as the ultrastructures of the two strains were investigated. Laccase was observed in the outer layers of the cell walls of both ...
