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)
Figs 51-54 Monodictys trichocladiopsis (HKU(M) 4739, holotype). 51 Portion of colony on natural substratum. 52–54 Conidiogenous hyphae bearing conidia. Septation of the conidia is obscured by the dark pigmentation. Scale bars: 51 = 5 µm, 52–54 = 10 µm. (Goh and Hyde 1999)
