THE BEITISH SMUT FUNGI 87
globose to sub-globose, light brown, reticulate (reticulations 2-4 JJ, wide, 2-3 /A
deep), 18-22 fi diam.
On Lolium temulentum, L. multiflorum, L. perenne, and L. remotum.
Welsh Plant Breeding Station, Aberystwyth. Introduced in seed of L. temulentum
from Portugal and infected the four species of Lolium named, in a pot
.experiment in 1937-8 (Sampson & Western, 1941).
Spore germination was figured by Kiihn (1858). The sporidia at the end of the
promycelium are shorter and wider than those of T. caries. Fusions of filiform
sporidia and the development of allantoid sporidia were shown.
Infection of the host occurs at the seedling stage (Sampson & Western, 1941).
Tilletia menieri Har. & Pat.
Tilletia menieri Hariot & Patouillard, Bull. Soc. mycol. Fr., xx, p. 61, 1904.
Sori in the ovaries filling the inflated grain with spores, partly hidden by the
glumes, 3-4 mm. long. Spore mass powdery, brownish black. Spores globose to
sub-globose, light brown, reticulate (reticulations 2-^ fj, wide, 1-5-3-0 /A deep),
20-26 fx. diam.
On Phalaris arundinacea.
August. Ireland (Antrim) (see A. L. Smith, Trans. Brit, mycol. Soc., iii, p. 374,
1911); England (Suffolk, Northumberland); Scotland.
Spore germination. Unknown.
ENTOEEHIZA C. Weber,
Bot. Zeit., xlii, p. 378, 1884
Type: Entorrhiza cypericola (Magnus) Weber on Cyperus flavescens, Germany.
Sori in swellings of the living roots of Cyperus and Juncus. Spores single,
thick-waUed. Spore germination by one or more germ tubes on which small
sicklei-shaped sporidia are developed.
Magnus (Verh. bot. Vereins Brandenburg, xx, p. 53, 1878) described a smut
causing swelhngs on the roots of Cyperus flavescens which he referred to the
genus Schinzia Naeg. as S. cypericola Magn. Because of the doubtful nature of
Schinzia, a genus erected by Naegeli {Linnea, xvi, p. 281, 1842) for two uncertain
species found in 7ns roots, Webert|1884) proposed a new genus Entorrhiza
based on E. cypericola (Magn.) Weber. Weber, however, united smuts from root
swellings of C. flavescens and Junxyus bufonius as E. cypericola and his observations
on the biology were made on material from the second host. Subsequently,
Magnus (1888) showed that the smut on C. flavescens (which has finely reticulate
or punctate spores) differs from that on J. bufonius^ (which has coarsely warted
spores) and proposed the name Schinzia aschersoniana Magnus {foe. cit., p. 103)
for the latter. Lagerheim in Aug., 1888, and de Toni in Oct., 1888 {Sacc. Syll.,
vii, p. 497), independently made the combination Entorrhiza aschersoniana.
This confusion has been reflected in the nomenclature adopted by different
authors for these smuts.
No British specimen has been examined. It is clear from the pubhshed records
that E. aschersonia on J. bufonius has been collected in Scotland but the species
involved in certain records on other species of Juncus is less certain.
