New species in Helicogloea and Spiculogloea, including a type study of H. graminicola (Bres.) G.E. Baker (Basidiomycota, Pucciniomycotina)

Two new heterobasidiomycetes species belonging to the genera Helicogloea and Spiculogloea (Pucciniomycotina) are described from Belgium. Helicogloea jozefii sp. nov. and Spiculogloea inaequalis sp. nov. are proposed with descriptions and illustrations of macroand microscopical features. The latter species grows as an intrahymenial parasite in Sistotrema spp. Identification keys to the new species are provided for each genus. The newly described species are compared to morphologically similar species and their ecology is briefly discussed. A type study of H. graminicola is included.
