"Quercirhiza cumulosa" + Quercus ilex L. subsp. ballota (Desf.) Samp.

Abstract

The ectomycorrhizae are characterized by black, loosely woolly, monopodial-pyramidal to irregularly pinnate systems. The outer mantle layers are pseudoparenchymatous, with angular cells and mounds of flattened cells, whereas the inner mantle layers are pseudoparenchymatous to tightly plectenchymatous. Emanating hyphae abundant, with clamps and surfaces with occasional warty patches. Dark brown rhizomorphs present, with thick central non-vessel-like hyphae surrounded by much thinner peripheral hyphae. "Quercirhiza cumulosa" is probably a member of the genus Tomentella.
