Teliospores in 2 — 5 layers, oblong, 25 — 50X 14—20/j; walls yellowish- brown, smooth, the upper spores greatly thickened at the apex (up to 11/i) and darker (Figure 68).. FIGURE 68. Phakopsora punctiformis (Barcl. et Diet.) Diet, on Galium aparine L. Teliospores (after Sydow) On leaves of Galiiim aparine, near Simla in India. Uredia distinguished from those of Thekopsora galii (Magnus, Ber. Deutsch. bot. Ges., XIV, 1896, S. 130. Taf. IX, Fig. 6,7) by the absence of elongate cells at the lower part of peridium and the presence of paraphyses. We have not seen specimens of this fungus, which was apparently fotind only once. On Compositae 2. Phakopsora c ompositarum J. Miyake, Bot. Mag. Tokyo, XXVII, 1913, p. 43. fig. Uredia hypophyllous, rarely caulicolous, minute, reddish-brown; peridia and paraphyses not mentioned. Urediospores 24 —28X 14 —18ju; yellowish; walls smooth. 345.
