Cordana abramovii E.O. Semen & Davydkina 1983

New Zealand. On wood of Beilschmiedia tarairi, Auckland Prov., Kirk's Bush, Papakura, 15.1.1963, S.J.H. PDD 36105 (DAOM 109508a).
Colonies effuse, black, hairy. Mycelium immersed, composed of pale brown to brown hyphae 3-5 um wide, here and there forming knots of dark brown cells. Conidiophores macronematous, unbranched, scattered or in groups of 2-5 arising from knots of hyphal cells, straight, flexuous or irregularly bent, up to 1200 um long, septate at 30-65 um intervals, sometimes bulbous and up to 15 um wide at the base, then 9.0-11.7 um wide, tapering gradually to 5.5-7.5 um toward the apex, dark brown and thickwalled (to 3 um) toward the base, pale brown and thinner-walled toward the apex which is somewhat swollen (up to 10 um) and which bears flattened to slightly denticulate scars each with a distinct central pore. Following the production of several conidia the conidiophore usually proliferates to produce another fertile swollen apex at a higher level: up to 7 such condiogenous swellings have been seen on condiophores. Conidia produced blastically on successive sympodial proliferations of the conidiophores, dry, broadly ellipsoidal, brown, 1-seplate, with a thick (2.0-3.6 um) layered wall; they are (23.6-)27-31 (-34) x 14.5-18.0 um and 3.5-4.5 um wide at the truncate base with a conspicuous, narrow cylindrical pore in the wall of the scar. Conidia secede schizolytically.
Cordana abramovii was described and illustrated, on fruitbodies of Aphyllophorales and wood of timber supports [pitprops] in mines in North Georgia, USSR, with conidiophores up to 1000 um long and thick-walled conidia 27-31 X 15.0-15.5 um. A collection of the same fungus on rotten wood from Agumbe, Karnataka, India was described and illustrated by Rao & de Hoog (1986) with conidia 18-25 X 12.5-14.0 um. These authors found the conidia of the type collection to be 22-31 X 14.0- um. They also drew attention to the pigmented pore of the septum and scar of the conidia in the USSR and Indian collections. The New Zealand collection also shows these features
