Pleomonodictys capensis

Pleomonodictys capensis (R.C. Sinclair, Boshoff & Eicker) Hern.-Restr., J. Mena & Gené, Stud. Mycol. 86: 77 (2017)

Basionym: Monodictys capensis R.C. Sinclair, Boshoff & Eicker, Mycotaxon 59: 359 (1996)

Index Fungorum number: IF 821221

Holotype: PREM 52106

 

Sexual morph: Undetermined. Asexual morph: Colonies effuse, dark brown to black. Mycelium partly

superficial to mostly immersed in the substrate, composed of branched, septate, pale brown to brown, smooth to verrucose, 1.5–3 μm wide hyphae. Conidiophores micronematous to semi-macronematous, mononematous, simple, straight or flexuous, pale brown to brown, verrucose, up to 130 μm long, 3–4 μm wide, cells infrequently swollen to 5 μm wide towards the apex. Conidiogenous cells monoblastic, integrated, terminal, determinate, cylindrical, verrucose, pale brown to brown. Conidia solitary, acrogenous, mostly obovoid but also pyriform to ellipsoid to subglobose, with slightly irregular margins,

dark-brown to black; becoming darker, thicker-walled, and more verrucose with age, with irregular, smooth-walled areas towards the apex, muriformly septate, septa obscured at maturity, 30–100 μm long, 17–60 μm wide, sometimes one or more basal cells more pale than the others, sometimes swollen to 8 μm wide. (Description from Sinclair et al. 1996)

 

Material examined: SOUTH AFRICA, Cape Province, on decorticated wood, Jul. 1994, R.C. Sinclair, PREM 52106, holotype; ex-type cultures CBS 968.97, PPRI 5984.

 

Notes: Monodictys capensis was mainly characterised by the irregularity in the conidial shape and ornamented wall (Sinclair et al. 1996). The ITS sequence of the ex-type strain CBS 968.97 and that retrieved from GenBank (LC014570) corresponding to Mel'nik's strain (CBS 134928) were identical, confirming the identification of this latter strain. (Notes from Hernández-Restrepo et al. 2017)

 

Freshwater distribution: Brunei (Ho et al. 2001)
