It has been shown by Tulasne, and others, that some ofthe discoid Fungi appear under two or more forms or phases, which resemble each. other in outward ap-pearance, but differin fructification. Inthe case of Calloriafusarioides, on nettlestems, there is a con-idial form in whichno asci are developed,but naked spores areproduced on sporo-phores. Later on,and upon the samestems, in companywith the conidia truecups are perfectedwhich contain ascix-foo and sporidia. Bothare of the same sizeand colour, and inwell-developed speci-mens it is difficultto distinguish themwithout the use ofthe microscope. Inthe case of Corynesarcoidcs the same re-semblance exists be-tween the two con-ditions. The formin which conidiaonly are produced was previously called Tremella sarcoidcs,and is of a peculiar reddish-violet colour, bursting inclusters through fissures in wood or bark.
