HYPHOMYCETES FROM CANADIAN STREAMS - III - ARCISPORA-BISAGITTARIA ANAM. GEN. AND SP. NOV

Arcispora bisagittaria, an anamorph with basidiomycetous affiliation, is described. It was isolated from foam in a stream in the Miramichi R egion, N. Brunswick. The fungus has conidia consisting of a nearly str aight axis and two median lateral branches, which are parallel and per pendicular to the axis. The proximal branch grows from the loop of the clamp in the middle of the axis, the distal one directly from the axi s. Each branch has a clamp on the outer side of its base. The conidial ends bear thin extensions. An unnamed athelioid teleomorph was obtain ed in one isolate.
