humid sub-alpine districts of the west and north would well 

 repay close investigation. The extensive forest fires which oc- 

 curred in 1920 and 192 1 left burnt ground on which many 

 interesting Discomycetes were found. I have to thank my 

 friend Mr J. Ramsbottom of the British Museum for his con- 

 tinued kind encouragement to give attention to the scientific 

 side of the subject and to him I owe a debt of gratitude which 

 I cannot sufficiently express for the benefit of his critical advice. 

 RAMSBOTTOMIA nov. gen. 



Ascomata terrestria, plerumque laeticoloria, parva, lata 

 primum orbicularia dein plana vel lenticularia, externe pilosa, 

 pilis coloratis; asci ampli, maturitate prominentes, operculati, 

 iodo non caerulescentes, octospori; sporidia globosa vel ovata, 

 aspera vel echinulata, hyalina; paraphyses conspicui, iodo atro- 

 virescentes, granulas coloratas continentes. 



This genus is best placed immediately following Boudierella 

 Sacc. in the Pseudo-Ascoboleae of Boudier's classification.

Hab. ad terram argillaceam nudam vel inter muscos in 

 collibus. Dunoon, Argyllshire. May 1921. 



This well-marked species was found in some numbers in a 

 small area at Dunoon. It much resembles Lamprospora 

 Crec hqtieraidtii (Cr.) Boud., but is abundantly distinct in the 

 densely pilose exterior. The hairs are very long, tubular, thin- 

 walled, and arranged in branching fascicles. 

 Lamprospora campy lopodis n. sp.

 libus, glabris, lenticularibus, minutis usque ad i mm. latis, ad 

 maturitatem expansis, tenuissime et laceratim marginatis, cor- 

 tice parenchymatico, e cellulis polygonatis mediocribus, ad
