222 A. Barclay — Additional Vvediueae from Simla. [No. 3, 



those which have 7 — 9 cells) measare when recently wetted 130 — 94 x 

 .23 — 25fi but exceptionally a spore of only two cells may be found, 

 measuring 44 x 24/u,. I have not observed the germination of these 

 spores ; but some spores collected in autumn and })ut into water did not 

 germinate, and from this I conclude that they must rest. On the other 

 hand some of these spores showed a cell here and there empty; so ap- 

 parently under special conditions they may also germinate at once. 



I am inclined to regard this fungus as distinct from PJir. Bardayi and 

 Thr. quinqueloculare, mihi. If it be identical with either, it is with Phr. 

 Bardayi ; but the spores of the latter are usually 6-eelled with smooth 

 surface (or with very shallow inconspicuous warts) somewhat less in 

 length and greater in diameter. I am also unable to match it with any 

 of the six species described by De-Toni* on species of Biihiis. I propose 

 naming it Phragmidium octoloculare. 



XEHODOCHUS, 



Xenodochus Claekiands, n. s. 



On Astilhe 7'ivularis, Ham. 



This fungus was collected by Dr. Clark in the Oheog forest about 

 the beginning of August. On one specimen there were large irregular 

 aecidial patches, especially on the stem, accompanied by hypertrophy, 

 just like that caused by Phragmidmm suhcortioium on JRosa woschata. 

 These aecidia were exceedingly brilliantly orange red : they occurred 

 also on leaves. The spores are very briglit orange red, in rows, squarish 

 or oblong, densely warted, thickened a little at one end (seen best in 

 empty spores) (PI. lY, fig. 5). They measure 31 — 26 x 26 — 22/a. 

 There were no paraphyses. 



But much more numerous were orange waxy looking beds, which 

 to the naked eye resembled Goleosporiuvi beds. These in many places 

 simply covered the nnder leaf surface. I noticed that in some parts 

 these orange waxy beds were gradually changing, and at others had 

 changed into black beds, naked, and under a field lens looking like 

 Puccinia beds. The spores from the latter are scraped off with difficulty, 

 and when examined under the microscope presented characters most 

 like those I have read described as Xenodochus spores. They have 

 characters, as far as I am able to judge, intermediate between this 

 genus and Phragmidium. The spores were in rows, usually 5 to 6 in 

 each row, pale brown, rows being sometimes transversally septate, at 

 others irregularly in various obliquities. The rows of spores were some-
