the authority of the Rev. M. J. Berkeley, and strong urgency of 
Dr. H. Bull. Afterwards it was equally strongly contested and 
opposed by Dr. Max. Cornu. Undoubtedly according to Fries, 
Collybia cirrhata has no sclerotium, and the figure by Batsch, No. 95, 
thus represents it. Examination of specimens collected this year 
has led me to confess to the error, whilst referring them to Bresadola’s 
Marasmuus. 
Gleosporium Bidgoodi Cooke. 
Pustules rather large, covered by the blackened cuticle, at length 
ruptured for the escape of the conidia. [he stroma upon which the 
conidia are produced is also blackened, but the conidiophores become 
hyaline above, bearing the narrowly elliptic conidia (18-20 x 4p) 
which have two nuclei. No direct evidence that eventually they 
become uniseptate. Journ. Roy. Hort. Soc. XXVL., pp. CXXXIX. 
and CXLI. 
On leaves of Odontoglossum. 
Has been known for six or seven years, but not described, Leaves 
were submitted to Mr. Bidgood in 1901, who declared it to be a 
species of Glaasporium, but we have awaited his description in vain, 
and now take leave to associate it with his name. ‘The conidia of 
Gleeosporium Vanillee are 14-16 x 6-7p 5 those of G. cimctum are 
10-15 x 24-34; those of G. oncidi are 14-17 x 44-6; those of G. 
orchidearum are 20-25 x 5-7; and those of G. affine are 14-20 x 4-6, 
but other features have to be taken into account as well as the 
dimensions of the conidia. 
Fusarium lini Bolley. U.S.A. Agr. Exp, St.. N. Dakota. Bull. 
50, 1901. 
Vegetative hyphz, light coloured, septate, branching irregularly, 
ramifying the tissue of the stems and roots of the host. Spore tufts 
(sporodochia) erumpent, compact, slightly raised, pale cream or flesh 
coloured. Sporophores short and closely branched, or conidia some- 
times arising from wart-like protuberances, upon a common bed, or 
stroma. Conidia 4-celled, fusiform, slightly curved or falcate 
(27 x 3 to 38 x 3am). 
Living in the humus of the soil, attacking the seedlings of the flax 
plant, causing the disease known as “ flax wilt.” N, Ireland. 
Already known in Holland, Belgium, Northern France, Germany 
and Ireland, but hardly known in Russia.

ous, subspherical, effused, gregarious, black, shining. Conidia 6-10
