摘要	Basidiome development of Amanita muscaria was examined with light microscopy and illustrated in line-drawings. The youngest primordium of a fruitbody of A. muscaria examined measures ca. 2 x 2 mm. At this stage, the primordial universal veil and the primordial bulb are already outlined. At the top of the bulb primordium, the hyphae are in an actively growing state and differentiate into stipe primordium and pileus primordium. With further development of the primordial pileus, the primordium of the hymenophore appears, then the gills develop. At first, thin vertical plates appear radially in regular distances in the hymenophore primordium. These plates consist of yellow to brownish, more or less irregularly arranged, degenerating hyphae. These hyphae are separated from vital hyphal segments by septa and disappear during the further development. Thereby the primordial gills are separated from each other. The vital terminal hyphal segments branch subterminally and regularly, thus forming the young hymenium. The gill differentiation proceeds radially away from the stipe or towards the stipe or in both directions. Hyphae at the gill edge are interwoven with those of the stipe volva during the early fruitbody development, so that they appear to be connected to each other. The primordial universal veil surrounding the upper part of the fruitbody primordium ruptures and disappears early during the development. Thus there are no remains of the primordial universal veil on the mature pileus. The white, yellowish warts on the pileus are derived from the pileal volva. The annulus originates from the stipe volva, which corresponds to the so-called lipsanenchyma between the stipe and the hymenophor. Schematic illustrations of basidiome development in A. muscaria and A. phalloides are provided.
