The small Discomycete which was diagnosed as Pseudophacidium 
Smithianum and afterwards placed in the genus Phaeangella was described 
by Phillips in the “Scottish Naturalist” 1891, p. 89, as Cenangiuyn 
Empetri . Phillips’ type specimen has been examined. The fungus must 
therefore be called Ehaeangella Empetri . Phillips’ description of this 
fungus does not occur in the English floras and was overlooked by 
Saccardo. Other new species described in the paper are Hymenoscypha 
symphoricarpi, Lachnella brunneo-ciliata and L. (.Heloiiella) Laburni; 
and a new variety Mollisia ( Niptera ) cinerella, Sacc. f. caespitosa.

SMITH, Lorrain, A. and RAMSBOTTOM, J., New or rare microfungi 
(Trans. Brit. Mycol. Soc. 1913, 4, 165—185). 
The authors in this paper gather together all the newly recorded 
British microfungi supplying diagnoses where such were not given with 
the record. The new fungi which have been forwarded to the British 
Museum are also incorporated. Eight species new to science are diagnosed: 
Orbilia Boydii (on Vaccinium Myrtillus) Sclerotinia muscorum (on 
Campy lopus atrovirentris ), Phyllosticta Acetosellae, Ascochyta art cola r 
A. Deutziae, A. Valerianae, Marssonia Aegopodii and M. Lappae .

RAMSBOTTOM, J., Some notes on the history of the classi¬ 
fication of the Uredin ales (Trans. Brit. Mycol. Soc. 1913, 4, 
77—106). 
In this paper the writer considers the history of the classification of 
the Uredinales chiefly with regard to the English Floras and the evolution 
of the present systems. Some of the old ideas concerning “blight” and 
“mildew” of corn are quoted. The English records of Aecidinm are 
traced and the suggestions of the connection between the stages on wheat 
and barberry. The work of observers leading up to the classical studies 
of Tulasne and de Bary are considered and its influence on the classi¬ 
fications of the group. An attempt has been made to notice all the 
principal systems put forward by various systematists. A key to the 
British genera is appended together with a full list of British species.

The fungus appeared on some cultures of damp soil containing dead 
earthworms (Lumbricus terrestris). The soil had been in glass or tin 
boxes for about six months when it was seen to be studded with hund¬ 
reds of minute fawn coloured spots. On microscopic examination the 
spots were seen to resemble a species of Gymnoascus. A full description 
is given of the fungus; an amended generic diagnosis and a specific
