. Comparative morphology of Fungi. Fungi. O^ooSH aads. Fig. 101.— Taphrina deformans. 1. Hymenium (X670). Taphrina Carpini. 2. Germination of asci in distilled water (X400). Taphrina aurea. 3, 4. Hymenium (X 330). (After Gwynne-Vaughan, 1922, and Sadebeck, 1884.) on Potentilla, the mycelium lives only in the interior of the leaves and the asci, as in Taphridium of the Protomycetaceae, are formed in a mycelial layer under the epidermis. In T. aurea on Populus and T. epiphylla on Alnus, the whole outer wall of the chlamydospores continues in the wall of the young ascus. There is no septum between ascus and chlamydospore, i.e., no abjunction of a stipe cell (Fig. 101, 3 and 4; 102, 4). The types of germination of these forms are occasionally strikingly reminiscent of the Protomycetaceae. In T. Coryli on Conjlus americana, the diploid nucleus divides into two daughter nuclei in the chlamydospore. One remains in the basal cell and degenerates; the other migrates into the young ascus and divides there into the 8 spore nuclei (Martin, 1924)..
