tium is represented by columnar props instead of a network of broad 

 strands. It has been obtained in Devon, Somerset, Wiltshire, Hamp- 

 shire, Surrey, Bedfordshire, Norfolk, and Argyllshire ; also from 

 France, Brandenburg, and New Hampshire. 



Triciiia floriforme (Schweinitz) Gr. Lister, syn. T. Bofryfis 

 Pers. var. lateritia Lister. The constancy of this handsome form 

 fully entitles it to specific rank. It dilfers from all varieties of 

 T. Botrytis in having dark red translucent stalks entirely free from 

 refuse-matter, as well as in the orange-coloured spores. It seems 

 unfortunate that the familiar name lateritia^ published by Leveille 

 in 18-1(5, cannot be retained ; but Dr. Sturgis found, when examining 

 the Schweinitzian herbarium, that the specimen described as (7r«- 

 terium iioriforme^(i\\\\idm\t7. in 1S82 is plainly the species in question, 

 and, by the rule of priority, tlie older name must be adoj^ted. 

 Although widely distributed, T. jioriforme is not common in Britain; 

 it has been recorded from Somerset, Wilts, Middlesex, Leicestershire, 

 and Shropshire. 



T. Botrytis Pers. var. cerifera G. Lister in Journ. Bot. 1915, 

 p. 211. Recorded in Britain from Derbyshire, Bedfordshire, Essex, 

 Somerset, and Dorset ; also from New South Wales. 



Hemitrichia leiotricha Lister. Recorded in Britain from 

 Dorset, Devon, Surrey, Essex, Hertfordshire, Bedfordshire, Shro])- 

 shire, Northumberland, and Aberdeenshire; also from Norway, Sweden, 

 North Germany, Switzerland, and Ceylon. 



H. ABIETINA (Wigand) Lister. Found for the first time in 

 Britain in the Woodhouse Pinetum, Uplyme, Devon, in February 

 1905 ; also obtained near Swarraton, Hants, and Hind Head, Surrey. 



H. MINOR G. Lister. The typical form was first found in Britain 

 by the Rev. W. Cran, near Skene, February 1912 ; and he has met 

 with it again repeatedly there and also at Lesmoir, West Aberdeen- 

 shire. Mr. N. G. Hadden obtained it on the mossy bark of living 

 trees at West Porlock, Somerset, November 1916. Here he also 

 found the handsome little dark-spotted var. pardina Minakata, growing 

 on hedge-clippings, in January 1919. In this gathering the spirals on 

 the capillitium are unusually well developed and are dextral in arrange- 

 ment, whereas in all specimens of typical H. minor hitherto obtained 

 the direction of the s^Dirals is sinistral, as is usual in the Trichiacecd. 

 In the type of var. pardina from Japan, the capillitium has faint and 

 variable spirals, some being dextral, others sinistral. Guided by this 

 character of the spirals, I examined a number of our old mountings, 

 with the result that I came across the record of two gatherings of 

 what I doubt not should be called H. minor var. pardina, made at 

 Lyme Regis in the years 1891, 1899. They came from the same 

 leaf-heap, and each consisted of a single sporangium. In appearance 

 they are shortly stalked and glossy yellow spotted with prominent 

 dark brown warts ; the capillitium shows dextral spirals ; one had 

 been called " H. Karstenii F," the other ** T. erecta Rex," and 

 afforded the only evidence for the occurrence of that species in 

 Britain. T. erecta is a much more sturdy species and has rich orange- 

 yellow capillitium with spinulose sinistral spirals ; it is widely dis-
