the sporangia were immature and watery white, but soon changed to 

 the inconspicuous brown mature stage. 



Amauroch^te cribrosa (Fries) Sturgis in Mycologia, ix. p. 328 

 (1917). This species has long been included under A. fuligiiiosa 

 (Sow,) Macbr,, from which it differs in the sethalia being smaller, 

 rounder, and more compact, and, when perfectly formed, being 

 clothed with a fragile membranous cortex, which either breaks into 

 fragments adhering to the tips of the capillitium or entirely dis- 

 appears ; the capillitium closely resembles that of Stemonites con- 

 Jiuen% Cooke & Ellis, to which A. crihrosa appears to be closely 

 allied. There seems to be every probability that this is the species 

 described by Fries as Lachnoholus crihrosus (Syst. Orb. Veg. p. 148) 

 as long ago as 1825, the type of which is lost. In Britain it was 

 found near Smethwick, Staffordshire, by Mr. A, Camm, August 1895, 

 and by Mr. T. Fetch in Hull dockyard in Sept. 1903, Elsewhere it 

 has been recorded from Sweden and Norway, and in North America 

 from the States of Massachusetts, Pennsylvania, and Washington. 



Cribraria yulgaris Schrad. In the British Museum Catalogue 

 this is named G. aurantiaca Schrad., and two varieties are dis- 

 tinguished : — -form a, a short-stalked form with broad nodes to the 

 sporangial net, a,nd form /3, a long-stalked form with naiTow nodes. 

 The species is very variable, but a more natural arrangement is that 

 proposed by Meylan (in Ann. du Conservatoire de Greneve, 1913, 

 p. 317) ; he regards C. vulgaris as the typical form, having slate- 

 grey Plasmodium, usually short-stalked sporangia with ochraceous 

 spores, and either broad or narrow *' nodes " ; and var. aurantiaca 

 Pers., having green plasmodium, usually longer stalked sporangia with 

 golden-yellow spores, and polygonal nodes approaching in character 

 those of C. tenella Schrad. or of G. intricata Schrad. 



LiCEA CASTANEA G. Lister. Discovered by Mr. Cran at Lesmoir, 

 W. Aberdeenshire, November 1910, and found again repeatedly 

 by him both there and near Skene. It has also been obtained by 

 M. Meylan in the Jura Mountains. 



L. MiNTMA Fries. Recorded first in Britain by the late George 

 Massee, from Bulmer, Yorks ; found since in Bedfordshire, East and 

 West Aberdeenshire, and Inverness-shire ; recently Miss M, Rea has 

 obtained it in County Down. 



HvMEXOBOLUS PARASITICUS Zukal. Fii^t found in Britain by 

 Mr. Cran at Rhynie, West Aberdeenshire, June 1894, and since 

 obtained repeatedly by him both there and near Skene ; also found in 

 the Cawdor Woods, Nairnshire. 



Orcadella operculata Wingate, Recorded first from Britain 

 by Mr. W. H. Burrell from Stratton Strawless, Norfolk, January 

 1909, on liverworts on a living beech-tree. Mr. Cran finds this 

 inconspicuous little species in abundance, also on living trees, near 

 Skene. It has been recorded elsewhere from Holstein, Japan, and in 

 North America from the States of Maine and Pennsylvania. 



Enteridiu^c liceoides G. Lister. This has hitherto been re- 

 tained as a variety of JE. olivaceuniy but, though nearly allied, it 

 always exhibits the flat pkismodiocarp habit, and the pseudo-capilli-
