Phallus impudicus has a rhizomorph system which can be separated from its matrix, thus providing an opportunity to study relations between fungal mycelium and fructification. Fine rhizomorph is composed mainly of longitudinal mycelium, and showed no disability in translocation of carbohydrate, fat, nitrogen, ash or total dry matter from rhizomorph to the relatively large fructification. Thick rhizomorph bore smaller fructifications with lower percentages of carbohydrate and nitrogen and, when it also became extensive, there was inadequate transport of all constituents from rhizomorph to the fructification, which apparently needs them quickly and in relatively large amounts. Thick rhizomorph is inefficient for longitudinal transport because it contains peripheral mycelium or consists of fine hyphae running in all directions. Some part of the ‘egg’, probably the mucilage, acts as a temporary reservoir of carbohydrate during the quick development of a fructification.
