Monodictys striata (Petch) V. Rao & de Hoog

Basionym: Sporidesmium striatum Petch, Ann. R. bot. Gdns Peradeniya 6(3): 249 (1917)

 

Description from Rao and de Hoog (1986) observed from a rotten bark in terrestrial:

Sexual morph: Undetermined. Asexual morph: Colonies on rotten bark expanding, farinose, black; under the stereo microscope scarce individual, ellipsoidal, erumpent sporodochia are visible, which are composed of densely aggregated, blackish conidia. Mycelium scanty, composed of moderately thin-walled, smooth-walled, pale olivaceous brown hyphae. Stromata absent. Conidiophores arising in dense groups from undifferentiated hyphae, short, composed of 1–3 rectangular cells. Conidia arising as terminal blown-out ends of conidiophores, initially broadly ellipsoidal, pale olivaceous with thin septa; conidial maturation by meristematic growth of the entire conidium; mature conidia golden brown, smooth-walled, moderately thick-walled, broadly ellipsoidal, broader than long, mostly asymmetrically inserted, 27–35 × 16–22 µm; conidia muriform, slightly constricted at the septa, often the median septum forms a rather straight, somewhat darkened line; conidial secession probably schizolytic.

 

Freshwater distribution: China (Tsui et al. 2000)
