zen. Trail, Scot. Nat. 1884,/. 243. 



In stems of Galium verum, causing the plants to remain 

 stunted and erect, and to resemble miniature Equisetum 

 palustre in habit. The stems become dull purple or black- 

 ish, either throughout, or at the nodes, with only dark streaks 

 in the internodes. The leaves are sickly yellowish-green, 

 with midribs, at base below, dull purple. The flowers are 

 seldom developed. The cortex of the stem is crowded with 

 spores of the fungus, usually in groups. The spores are 

 rounded, or frequently more or less angular, from mutual 

 pressure ; are usually dark brown, and moderately thick 

 walled, and vary from 17 by 12 to 25 by 20.

Frequent on Sandy Links, near Aberdeen, and at Muchalls on 

 cliffs. J. W. H. Trail. Probably this fungus is common 

 along our sandy coasts. 



3063. Entorrhiza cypericola (Magnus) Weber. Bot. Zeii. 1884, 



pp. 369-79. Trail, Scot. Nat. 1884, pp. 241-43. 



Causes swellings in the tips of roots of Juncus bu/onius. 

 These are usually white, oval, smooth or nearly so, and vary 

 from the size of a pin-head to that of a pea. After a time 

 they become brown. The cells of the inner cortex are en- 

 larged, and are occupied by spores connected by very deli- 

 cate mycelium filaments. The spores are round or oval, 

 and reach 20 by 17. They have a thin endo-sporc, and a 

 yellow or red-yellow epispore bearing low warts.

Near Aberdeen, in one or two places. J. W. H. Trail. Prof. 

 B. Balfour tells me that he has found considerably larger 

 branched tumours on roots of Juncus (lamprocarpus f) near 

 Glasgow, which apparently are caused by the same, or by 

 an allied, species of fungus. 



3064. Tilletia bullata Fckl. Sym. Myc. p. 40. Grevillea, Vol. V.

Epiphyllous. Sori bullate, orbicular, purplish-black ; 

 spores globose, purplish-brown ; epispore minutely granu- 

 lated. Caeoma Bistortarum, Libert Exs. 88.
