在许多真菌上观察到液滴粘附在菌丝上的渗出物，对F. culmorum的详细研究表明，液滴的分布与菌落形态有一定的关系。渗出过程可能具有生理意义，液滴的特性、吸收和再渗出、它们在孢子形成中的明显作用及其生化含量支持了这一前提。液滴似乎与菌落老化密切相关，并且随着这一过程的发生，它们的性质也发生了变化。最初它们是透明的，像水一样，但随着菌落的发展，它们变成粒状和不透明的，在某些情况下，它们充满了孢子。讨论了微滴的发育顺序、微滴的释放机制及其在机体正常生理功能中的作用。
Exudates were observed on a number of fungi as liquid droplets adhering to the hyphae, and detailed investigation with F. culmorum showed a definite pattern in distribution of the droplets in relation to colony morphology. The process of exudation may be of physiological significance and specific properties of the droplets, absorption, and reexudation, their apparent role in spore formation and their biochemical contents support this premise. Droplets appear to be closely associated with colony aging and their properties change as this process occurs. Initially they are transparent and water-like but become granular and opaque, and in some instances packed with spores as the colony develops. The sequence of droplet development and a mechanism for the release of these droplets and their function in normal physiological functioning of the organism is discussed.
