Paradictyoarthrinium diffractum

Paradictyoarthrinium diffractum Matsush., Matsush. Mycol. Mem. 9: 18 (1996)

 

Colonies on MEA growing up to 6 cm in 10 days, off-white to brown, becoming dark brown to black after sporulation. Mycelium 1–3 µm broad. Conidiophores macronematous, rarely micronematous, short, when macronematous showing much varied morphology, unbranched to much braturnched, uneven, constrictted at septa, turning brown to dark brown on maturity, 10–75×4–5 µm, part of mae conidiophores often released along with conidia. Conidiogenous cell blastic, mostly terminal, 4–10×4–5 µm. Conidia 2 to many unevenly dictyoseptate, circular to irregular, dark brown to black on maturity, 8–33×10–30 µm.

 

Known distribution: As per USDA fungal distribution database and other available literature the fungus is so far known only from its type locality at Rustenbusrg in South Africa from dead plant material collected from a rivulet.

 

Material examined: India, Goa, Canacona, Mashem, on dead decaying spathe of Cocos nucifera, 2 January 2007, A. Prabhugaonkar, Herb. No. GUBH 136AP25; culture no. GUFCC 15514.
