Description
Biconidium H. Y. Wang & Y. F. Han gen. nov.
Etymology.
Referring to the bicellular conidia.
Description.
Mycelium hyaline, septate, smooth, thin-walled. Conidiophores hyaline, septate, smooth-walled, solitary, straight, (sub-) erect, arising directly from hyphae, unbranched or branched, bearing 1–5 levels with 1–6 phialides per node. Conidiogenous cells enteroblastic, monophialidic, lateral or terminal, awl-shaped, hyaline, smooth, with globose to cylindriform thickening at conidiogenous loci. Conidia bicellular, podiform, unsymmetrically at both ends, hyaline, thick-walled, smooth, arranged in slimy heads. Chlamydospores and sexual morph absent.
Type species.
Biconidium sinense H. Y. Wang & Y. F. Han
Notes.
Three isolates from green soil of sewage treatment plant clearly form an independent clade on the ITS and LSU tree (Fig. 1), and are phylogenetically segregated from other genera, representing the new species with conidiogenous cells with globose to cylindriform thickening at conidiogenous loci and podiform conidia arranged in slimy heads. Therefore, we introduce Biconidium as a new genus to accommodate this species.
