Lophodermium piceae Marasmius androsaceus Thysanophora penicilloides ? Mushrooms in a MOR on spruce needles
OF Figure 3 zo % volume roots excluded 90 10 noz OFzo : zoogenic transformed material > 10 % of the volume of the horizon after removing living roots. OFnoz : non zoogenic transformed material >= 90 % of the volume of the horizon after removing living roots. ZOOGENIC TRANSFORMED MATERIAL = RECOGNIZABLE REMAINS AND HUMIC COMPONENTS processed by animals = leaves, needles and other plant residues more or less degraded by soil animals, mixed with animal droppings. A fine powdered and/or grained structure (less than 1 mm) is typical in a terminal stage of faunal attack in an organic horizon. At this last level of biotransformation, the substrate (OH horizon) is essentially comprised of organic animal droppings of varying size (droppings of epigeic earthworms, macroarthropods such as millipedes, woodlice and insect larvae, microarthropods such as mites and springtails and enchytraeids dominate). Within hemorganic horizons, animal activity leads to different types of A horizons, depending on the animals’ ability to dig into the mineral soil and thoroughly mix organic and mineral matter. NON ZOOGENIC TRANSFORMED MATERIAL = REMAINS AND HUMIC COMPONENT processed by fungi or other non-faunal processes = leaves, needles and other plant residues more or less fragmented and transformed into fibrous matter by fungi. Recognizable and recent animal droppings are absent or not detectable by the naked eye in the organic horizons; fungal hyphae can be recognized as white, brown or yellow strands permeating the organic or hemorganic substrates; traces of animal activity (old bite marks, mucus) may sometimes be detectable but are always marginal. In the last stage of biodegradation of an organic horizon, non zoogenic substance may essentially be composed of brown, dry plant residues more or less in powder form or tiny fragments (OF and OH horizons), or be massive like a dark wet plastic clay (OH or very organic A horizons).
