The mycelium grows to long distances over or through the sup- porting nutrient me- dium, often forming conspicuous long-lived _xii resistant rhizomorphic strands or sheets, some- times developing sclero- tia or again appearing as a mere floccose weft. The basidia bear four simple spores, in rare cases two, six or eight. Other forms of conidia are found in some spe- cies and chlamydospores may be borne either ex- ternally on the sporo- phore, in the hymenium, or inside of the sporo- phore tissue. In the lowest forms the basidia arise directly from the mycelium without the formation of any definite sporophore but in most species the sporophore is highly complex, consisting of large, stalked or sessile, pseudoparenchymatous structures (toad- stools, mushroom, etc.) on special surfaces of which, the hy- menium, Fig. 286, lies; covering gills or spines or lining pits or pores.
