Abstract or Summary
  • Cultural and developmental characteristics of a collection of Anthracobia melaloma with a brown hymenium and a barred exterior appearance were examined. It grows well in culture on CM and CMMY agar media and has a growth rate of 17 mm in 18 hours. It is heterothallic and produces asexual multinucleate arthrospores after incubation at 30°C or above for several days in succession. These arthrospores germinate readily after transfer to fresh media. Antheridial hyphae and archicarps are produced by both mating types although the negative mating type isolates produce more abundant archicarps. Antheridia are indistinguishable from vegetative hyphae until just prior to plasmogamy when they become swollen. Septal pads arise on the septa separating the cells of the trichogyne and ascogonium subsequent to plasmogamy and persist throughout development. The paraphyses, the ectal and medullary excipulum, and the excipular hairs are all derived from the sheathing hyphae. Ascogenous hyphae and asci are derived from the largest cells of the ascogonium. A haploid chromosome number of four is confirmed for the species. Exposure to fluorescent light was unnecessary for apothecial induction, but did enhance apothecial maturation and the production of hyrnenial carotenoid pigments. Constant exposure to light inhibited the production of the brown hair pigments.
