. Comparative morphology of Fungi. Fungi. Fig. 47.—Basidiophora entospora. a, two conidiophores emerging from a stoma; st, short sterigma which forms a conidium; b, conidium with apical papilla and remains of stalk; c, zoospore from germinating conidium; d, oogonium with mature oospore, whose exospore is ridged. Empty antheridium at the right, (a X 230; b X 540; c, d X 550; after Roze and Cornu.) capable of germination up to 11 months. In some species of Albugo, the wall is thickened equatorially, forming a ring (annulus). Furthermore, in Albugo the first conidium of a chain is generally large

In some species of Albugo, the wall is thickened equatorially, forming a ring (annulus). Furthermore, in Albugo the first conidium of a chain is generally larger than the others and has a membrane of even thickness. When such a conidiophore, by raising the epidermis from the tissue, breaks out of the host and the spore chains break up, these first conidia remain clinging to the epi- dermis of the host. Possibly these serve exclusively to raise the epi- dermis and are not capable of germination. Therefore they are called ''buffer ;.
