Monodictys trichocladiopsis

Monodictys trichocladiopsis Goh & K.D. Hyde

Index Fungorum number: IF 459998

Etymology: trichocladiopsis, referring to the conidia of this taxon in which the septa are obscured by dark pigmentation and thus superficially resemble those of Trichocladium species

Holotype: (HKU(M) 4739)


Sexual morph: Undetermined. Asexual morph: Colonies on natural substratum effuse, black, glistening. Mycelium partly superficial and partly immersed, comprising subhyaline to pale yellowish

brown, 1.5–2 µm wide, smooth or verruculose, septate, branched hyphae. Setae and hyphopodia absent. Stromata not developed. Conidiophores micronematous. Conidial secession rhexolytic. Conidia 30–40 × 20–25(–27) µm borne on undifferentiated hyphae, solitary, scattered or in loose clumps, ellipsoidal or pyriform, smooth-walled, black, dictyoseptate, septa often obscured by the dark pigmentation; basal cell subglobose, yellowish brown, 4-5 µm diam. (Goh and Hyde 1999)


Material examined: CHINA, Hong Kong, Plover Cove Reservoir, on submerged wood, 15 Nov. 1996, Michelle K.M. Wong and K.D. Hyde, PC52 (HKU(M) 4739).


Freshwater distribution: China (Goh and Hyde 1999)
