摘要: Abstract A previously unreported free-living form of Pilayella is described. During all months the year, drifting clouds this plant may carpet up to half sandy bottom and beaches Nahant Bay, a 15 km2 rectangular embayment on north coast Massachusetts. Four features distinguish atypical from typical attached species: (1) ball shape concomitant general lack polarity in development central axes; (2) polystichous condition present throughout much (3) dearth reproductive organs; (4) peak summer-time abundance hundreds tonnes (live weight). Plant reproduction growth appear result fragmentation subsequent regeneration solely by vegetative cell division. Fragmentation results seasonal senescence filamentous axes infection marine fungus Eurychasma dicksonii. The drift community characterized its virtual monospecificity weight,...
