Conicomyces nassensis, a new synnematous fungus from the Nass River valley, British Columbia

Abstract

The new hyphomycete species Conicomyces nassensis is described based on a specimen collected on Pinus contorta wood in the Nass River valley of British Columbia, Canada. The species produces black synnematous conidiomata up to 3000 μm tall, with a terminal concave conidiogenous zone of intermixed sterile hyphae and percurrently or sympodially proliferating conidiogenous cells, and a yellow slimy mass of 11-21-septate phragmoconidia, 96-116 × 4-5 μm, with a single terminal appendage about 1/2 the length of the conidium body. The species is compared with the two other species currently classified in this genus.
