摘要
Several new species belonging to the anamorph genera Bactrodesmiastrum and Bactrodesmium, collected from plant debris in Spain, are described and illustrated. Bactrodesmiastrum pyriforme sp. nov. is characterized by large, pyriform conidia. Bactrodesmiastrum obovatum comb. nov. is proposed to accommodate Janetia obovata, and the Spanish specimen of B. obscurum, the type species of the genus, represents the second known collection of the species worldwide. Analyses of rDNA sequences confirm the distinction between B. obovatum and B. pyriforme and reveal their relationships with the Savoryellales (Sordariomycetes). Bactrodesmium diversum sp. nov. is distinguished from the other species of the genus by its large, pale brown conidia with a conspicuous pore at each septum.
