The paper reviews the types of substrata inhabited by non-poroid resupinate Homobasidiomycetes in situin global scale with both examples from literature sources and from observations on Belarus corticioid fungi biota. The groups of organic world colonized by corticioid basidiomata and vegetative mycelium are arboreous, semi-arboreous, and herbaceous vascular plants, Bryophyta, epiphytic coccoid algae, lichenized and non-lichenized fungi, and occasionally myxomycetes and invertebrates. The fungi occur on living, dying, and dead on all decay stages parts of organisms. Besides, the fungi are known on soil, humus, stones, artificial inorganic and synthetic materials and dung.
A coelomycete with appendage-bearing conidia, R. sessilis, was isolated three times from stems of living healthy Pinus sylvestris seedlings of the 1st year growing in a nursery in central Belarus. Macroscopic and microscopic morphology of the fungus in culture is described.
