Telia on overwintered leaves, hypophyllous (occasionally also epiphyllous) on brown areas of indefinite extent. Teliospores intraepidermal, sometimes completely filling the epidermal cells, also within the guard cells,1- to 40-celled; cells 8-25 X 7-15|U. Basidiospores globoid or subgloboid, — across. Aecia on Abies alba Mill, and A. concolor (Gord.) Lindl. in culture. Uredio- and teliospores on Phyllitis scolopendrium (L.) Newm. ( = Scolopendrium vulgare Smith). In Japan on Phyllitis scolopendrium, occurs Milesia scolopendrii var. sublevis Faull (, p. 117, tab. VI, fig. 23) ( = Milesia sublevis Hirats. f., 1. c, p. 111), with short echinulations or verrucules on urediospore walls. According to Kamei (1933) aecia on Abies mayriana (quoted from Hiratsuka, 1936, p. 113). General distribution: Europe (including the Caucasus). On Phyllitis scolopendrium (L.) Newm. — EUROPEAN PART: M Dnp. ("Les na Vorskle" [Forest on the Vorskla"] (Brezhnev)); CAUCASUS: W Transc. (Kelassuri (Siemaszko), TsebeI'da (Voronov), near Sukhumi). In experimental infections carried out by Hunter (l. c.) in England, teliospores sown on Abies alba and A, concolor produced aeciospores, which proved infective for Phyllitis scolopendrium but failed to infect Blechnum spicant, Dryopteris spinulosa dilatata, and Polystichum FIGURE
