Fungi. i8o INTRODUCTION TO THE STUDY OF FUNGI Some mycologists have advanced the opinion that at least many of the species of the genus of moulds named Botrytis are the conidia of some species of Peziza. It has been shown by Tulasne, and others, that some of the discoid Fungi appear under two or more forms or phases, which resemble each other in outward ap- pearance, but differ in fructification. In the case of Calloria fusarioides, on nettle stems, there is a con- idial form

It has been shown by Tulasne, and others, that some of the discoid Fungi appear under two or more forms or phases, which resemble each other in outward ap- pearance, but differ in fructification. In the case of Calloria fusarioides, on nettle stems, there is a con- idial form in which no asci are developed, but naked spores are produced on sporo- phores. Later on, and upon the same stems, in company with the conidia true cups are perfected which contain asci and sporidia. Both are of the same size and colour, and in well-developed speci- mens it is difficult to distinguish them without the use of the microscope. In the case of Coryne sarcoides the same re- semblance exists be- tween the two con- ditions. The form in which conidia only are produced was previously called Tremella sarcoides, and is of a peculiar reddish-violet colour, bursting in clusters through fissures in wood or bark. The perfect.
