Wiesneriomyces conjunctosporus Kuthub. & Nawawi
Holotype: IMI 318659
Etymology: conjunctus (L.) - connected et spora – spore
Asexual morph: Colonies effuse, olivaceous-brown to dark brown. Conidiomata sporodochial solitary to gregarious, on a dark pseudoparenchymatous stalks, consisting of 2–3 µm, dark, inflated, thick-walled cells, with 2–10 setae arising at the margins of the stalk base. Setae subulate with acute apex, septate, thick-walled 2–3 µm diam., dark brown up to 650 µm tall, 9–11 µm wide at the base. Conidiophores semi-macronematous, arising close to one another, pale brown to subhyaline at the base, hyaline towards the apex, septate, 1–3 times branched, 37–60 µm tall, 1.5–3.0 µm wide, with primary, secondary and tertiary branches. Conidiogenous cells terminal, cylindrical, hyaline, integrated. Conidia hyaline, aseptate, cylindrical, 15–21 µm cells connected by narrow short isthmi separating the conidia. Conidia in chains arising (280–360 µm long) from a single conidiogenous cell. Sexual morph: undetermined. (Description from Suetrong et al. 2014)
Material examined: MALAYSIA, Negeri Sembilan, Pasuh Forest Reserve, on rotten submerged angiospermic leaves, October 1986, A.J. Kuthubutheen, IMI 318659, holotypus.
Notes: Wiesneriomyces conjunctosporus differs from W. laurinus in several respects. Generally, the conidiomata of W. laurinus are smaller with shorter setae than those of W. conjunctosporus. Setae of W. laurinus are incurved around the conidial mass whereas those of W. conjunctosporus are erect and straight. (Notes from Kuthubutheen and Nawawi 1988)
Freshwater distribution: Malaysia (Kuthubutheen and Nawawi 1988)
