A new species of Arachnophora from submerged wood in the Amazon rainforest, Brazil

Arachnophora combuensis sp. nov. is described and illustrated from specimens collected on submerged wood from Combu Island (Belém municipality, Pará, Brazil) in the Amazon rainforest. The fungus is characterized by simple pale brown conidiophores, monoblastic percurrently extending conidiogenous cells, and staurosporous conidia with a pale brown basal cell and 2–3 dark brown central cells that bear 1–3 conical pale brown arms. The new species is compared with morphologically similar taxa.
