Chlamydospore formation during basidiospore germination in Marasmius oreades

Abstract

In Marasmius oreades germination of a basidiospore on 2.0 % malt agar gives a relatively long, narrow germ-tube that soon branches to produce a mycelium. However, on 0.2 % malt agar either the basidiospore gives a short, fat germ-tube which soon ceases to grow and in which a single chlamydospore is formed, or a chlamydospore is formed within the basidiospore without any germ-tube being produced.
