The thalli of these fungi are typically microscopic and varied. ... sexually, survive? Mycelium of Basidiomycetes: The well developed, filamentous mycelium consists of a mass of branched, septate hyphae generally spreading in a fan-shaped manner. a sporic life cycle, with a multicellular haploid and diploid thallus is produced during its life cycle. The production of asexual and sexual spores at different times during the life cycle of a fungus is of selective value, with asexual reproduction normally occurring at optimal conditions and sexual reproduction occurring when conditions are less favorable. Most are parasites of algae and animals or live on organic debris (as saprobes). Sexual reproduction. pythiensis) was later discovered in a species of (Sarkar Pythium and Dayal, 1988).
