SOME SCOTTISH RUST FUNGI 47 
Conopodii-Bistorte Kleb. occurs on Polygonum Bistorta and P. vivi- 
n 
Kleb. produces its teleutospores on Polygonum Bistorta. In this 
case the apical wall of the teleutospore is unthickened, and the 
papilla is very small; a similar papilla is found on the lower part 
of the lower cell beside the pedicel. P. mammillata has not been 
recorded from Britain. 
Pucornta ANTHOXANTHI Fckl, 
Puccinia Anthoxanthi has only been occasionally found in 
‘tai 
Yorkshire. During the summer of 1914 I collected the uredo- 
Spore stage of this species on Ben Voirlich (Loch Lomond), and 
also in the neighbourhood of Ben Lui (Perthshire), and in both 
these localities it appears to be widespread ; no teleutospores were 
found, although these were searched for in October. The speci- 
mens agree with those collected by Plowright in the possession of 
numerous thick-walled capitate paraphyses in the uredospore 
orus. In the original account given by Fuckel (as quoted by 
Saccardo) there is no mention of these paraphyses, and Sydow’s 
escription is similar in this respect. Fischer was unable to find 
paraphyses in the specimen in Sydow’s Uredineen (No. 458), but 
found them in a doubtful specimen on Anthoxanthum trom Switzer- 
land. McAlpine found none in specimens from Australia, which 
showed 2-4 very distinct germ-pores on one face of the uredospore. 
Sydow states that the species is not uncommon in mid- 
Germany, and during July, 1914, I was able to collect specimens 
of the fungus on Anthoxanthum odoratum in the neighbourhood 
of Marburg am Lahn (Hesse). y the uredospore stage was 
found, and this agreed exactly with that of the Scottish specimens, 
the paraphyses being particularly obvious. 
n view of the discrepancies as to the occurrence of these 
the matter appeared desirable. The specimens preserved in the 
herbarium of the British Museum I have investigated with the 
following results :— 
Specimens from Sydow’s Uredineen (No. 458).—Uredospores 
16-22 x 11-16 p, usually with 2-3 equatorial germ-pores, but 
these are not well marked; paraphyses absent. Specimen from 
Sydow’s Mycotheca marchica (No. 1218).—Uredospores 25-30 
x 16-20 p, with no clearly marked age ea paraphyses 
absent; mesospores present. Specimen co | 
(Fungi Rhenani, No. 2427).—Uredospores 20-25 x 17-20 p 
with 2-3 equatorial germ-pores; paraphyses absent.
