infected. All observed aecia located on both sides of cone scales with 96 % of the
aecia per cone being currently sporulating or had finished sporulating being
ruptured. From the mid-June to early October, 22 % - 45 % of the sample cones
carried T. areolata aecia. All infected cones carried aecia on both sides of cone
scales with 93 % - 100 % of the cone scales per cone carrying aecia.
3.2.2. Stand 2
In cones collected in October 2006, 90 % carried T. areolata aecia and 10 %
carried C. pirolata aecia. Aecia of T. areolata were non-sporulating and located in
both sides of cone scales with 94 % of the scales per cone being infected.
Chrysomyxa pirolata aecia had all finished sporulating, locating in 77 % of the
infected cones on the outer side of cone scales.
In late March in 2007, 90 % of the scales carried T. areolata aecia on both sides
of the scales in previous year’s cones that were non-sporulating. About 2 % of
these cones carried already sporulated and ruptured C. pirolata aecia on outer side
of the scales with 70 % of the scales carrying aecia per infected cone. In the early
May of 2007, 43 % of the sample cones carried T. areolata aecia and 7 % carried
C. pirolata aecia .
From late May to late June, 95 % of the sample cones bore T. areolata aecia and
15 % bore C. pirolata aecia. Aecia of T. areolata occurred on both sides of cone
scales in most of the cones with 86 % - 93 % of the scales per cone carrying
fruitbodies. All C. pirolata aecia had finished sporulating.
In late July and early October, 92 % - 94 % of the sample cones carried T.
areolata aecia, and 0 % - 19 % of them carried C. pirolata aecia. The average
proportions of cone scales bearing T. areolata aecia were 89 % - 95 % per cone.
On average, 18 % - 23 % of the scales per cone carried sporulating T. areolata
aecia.
3.3. Rust incidence and sporulation on alternate hosts
3.3.1. Stand 1
In late May 2007, 1 % of the overwintered O. secunda leaves bore C. pirolata
uredinia and undifferentiated fruitbodies. Undifferentiated fruitbodies were
common on O. secunda in late June, but after that they became rare. Uredinia were
common between mid-June and early August, after which they became rare. No
sporulation was observed in these uredinia until early August in 2007, after which
uredinia finished sporulating and ruptured. None of the current-year leaves of P.
padus bore any T. areolata fruitbodies in late May, but practically all leaves carried
uredinia from mid-June on and telia without basidia since late-June.
3.3.2. Stand 2
In late March 2007, none of the overwintered O. secunda and Pyrola sp. leaves
carried C. pirolata fruitbodies. Undifferentiated fruitbodies occurred first in early
