Forest microfungi. II. Additions toAcrodictys

摘要

The brief history ofAcrodictysM. B. Ellis is reviewed and two new species from rotting bark ofPopulusare described and illustrated.Acrodictys fuliginosan. sp. is characterized by non-proliferating conidiophores and obovate, shining-black conidia with three transverse and three to six longitudinal septa. InAcrodictys excentrican. sp. a succession of variably shaped shining-black conidia is formed from the long, readily proliferating conidiophores. Conidia are typically five-celled, one of the two apparently lateral pale brown inflated cells is the recurved apical conidium cell and the other is separated from the basal conidium cell by a longitudinal septum.
