FiG. 88. stance minute spherical yellow bodies appear on the surface ofthe mycelium, and these gradually enlarge until they becomejust visible to the naked eye, and acquire a dark brown colour(Fig. 87). These are the perithecia, ormembranaceous capsules, attached at thebase by a copious mycelium and surroundedby a circlet of free arms, or processes, asappendages, which vary in the differentgenera. In Erysiphe they are thread-likeand flexuous, of equal diameter throughout,and simple. In Uncinida the arms arehooked or curved at the tips (Fig. 88), InPhylladinia the appendages are straight, and often inflated atthe base. In Sphacrothcca they are flexuous and sometimesvaguely branched. In Podos2jhaera theappendages are repeatedly forked at thetips, as they are also in Microsphacra(Fig. 89). Internally these globoseperithecia are replete with the ascigerousfructification. The asci are nearlyglobose, or pear-shaped, and containhyaline elliptic sporidia.
