TRICHIA VERRUCO i Be a i September, 1904, we found this 
species with spo sits clustered on common membranous stalks, 
ing on a rotten larch-stump in the ravine in N. Wales, close to 
where it ‘a been collected by Mrs. Bradford in January, 1899 (s (see 
Journ. Bot. 1899, 151). This is the third British record we are 
acquainted with; it is the species that abounds in New Zealand, as 
described by Miss Hibbert-Ware in the account of the Myestoto of 
that country published in the April number of this Journa 
BeprorpsHirE Mycrtozoa. 
Dorine the past summer Mr. James Saunders, of Luton, has

Amongst the many ri ae vide he visited he fo ‘nd’ shbes standing 
on the chalk-marl most repaying his search, for there the soil 
retained moisture, and the heaps of old straw left by the less 
careful farmers about their stacks had become sodden, and afford 
abundant nutriment for plasmodium ; the season proved a favour-

exceptionally wnitable feeding-ground for many species of the group.

Saunders in the neighbourhood of Luton, bie: appeared there 
regularly and often in countless profusion for six years, from 1897 
until 1902, but have not been found there since. Badhamia ovispora 
Racib. was obtained in the same years, omitting 1900, and again in 
Aug. 1904, when the characteristic minute sporangia appeared in 
greater abundance than ever on straw,at Stopsley Common and 
Chaul End. 
Perhaps the most striking feature of last season’s gatherings o
