Dendrominia burdsallii (Corticiales, Basidiomycota), a new species from Arizona

Abstract

Dendrominia burdsallii is proposed as a new species that occurs on bark of living Arbutus arizonica in southern Arizona. Its most striking feature is the very large, narrowly cylindrical to allantoid basidiospores, (30–) 37–50 × 10–12 (–13.5) µm, with hyaline, thin, smooth, acyanophilous walls.
