Melanconium hedericola
Crous & R.K.Schumach.
Study description
General: Parasitic coelomycete on living leaves of common ivy (Hedera helix), producing a fine whitish pruina and ill-defined discoloration on the upper leaf surface.
Conidiomata: Pycnidial, deeply immersed in host tissue, erumpent, black, 0.2-0.4 mm in diameter, scattered across infected patches.
Conidiogenous cells: Cylindrical, erect, smooth, hyaline, simple and unbranched, 7-14 x 1.8-2.5 µm, holoblastic.
Conidia: Cylindric-ellipsoid to oblong, smooth, hyaline, thin-walled, 6.5-8.1 x 2.3-3.1 µm, containing two distinct polar lipid guttules.
