NOTES ON HYPOCREACEiE. 
By M. C. Cooke. 
It is not our intention to proceed in detail with observations on 
some of the remaining groups of Saccardo’s ‘‘ Sylloge,” since such 
a course would involve a considerable amount of labour, and no 
small expenditure of space. It is very generally known what our 
views are with regard to such a carpological arrangement, and 
therefore these need not to be repeated at every step. We shall 
therefore content ourselves with giving the diagnoses of additional 
species ; and probably, in some form or other, print our method of 
grouping the species, as classed in our own Herbarium, and that 
of the Royal Gardens at Kew. 
One point must, however, be noticed, in passing, with regard to 
the genus Nectria. We have long considered that, inasmuch as 
cgespitose species are kept generically distinct from those in which 
the perithecia are scattered, in other sections of Pyrenomycetes, so 
in this genus they should be separated, retaining the old name of 
Nectria for the caespitose species, and adopting one of Saccardo’s 
subgeneric names, viz., that of Dialonectria, for the discrete species. 
Other divergencies from the method adopted in the work above 
named we must leave to justify themselves. Those who hold views 
similar to ourselves will appreciate our endeavour to bring the two 
systems into working order, so that, whilst maintaining our 
opinions, we may still turn the labours of Professor Saccardo 
to the best account that we can. 
We have preferred to supplement Hypocreacece by a subdivision 
into three sub-families : (i.) Hypocreoide^ for the genera of 
compositae forms ; (ii.) Nectria for the simple or caespitose 
groups of true Nectria allies ; and (iii.) Pseudo-nectri^ for 
those aberrant genera, which we do not feel justified in placing in 
the second sub-family. 
We enter upon this method with a desire to adopt all that we 
can, with a good conscience, accept of the scheme of the “ Sylloge,” 
and to reject such as we may not approve, without acrimonious and 
unnecessary discussion.

Mycelio sclerotioideo, cylindrico, subarcuato, atropurpureo, nigres- 
cente. Stromatibus solitariis, vel binatis, vel ternatis, simplicibus, 
carnosis, albo-flavidis ; clavula elongato-clavata, flavo-carnea, e 
peritheciis laxis subliberis prominentibus asperula (peri. *4 x *18

angustissimis, linearibus ; sporidiis filiformibus (*14 mm. long). 
On ergot of Glyceria Jiuitans. (A. S. Wilson.) 
Differs from all other species in the elongated clavate capitulum 
and in the lax manner in which the perithecia are produced.
