96 Prof. Marshall Ward, Notes on some of the Rarer 
Sclerotinia Duriceana, Tub, Quel. 1 
This interesting peziza is comparatively abundant in some of 
the Fens, on Gar ex stricta, as was shown me by Dr Plowright. 
The sclerotia fit into the triangular leaves and stems, and when 
freed have a curious resemblance to Ergot. They germinate 
freely, and I found the peziza form fully developed in April, in a 
Fen in Norfolk. 
The ascospores germinated readily in water, and gave rise to 
the curious flask-shaped bodies emitting minute conidia, which have 
been described by Woronin 2 for other species of Sclerotinia. 
In richer food-materials, the ascospores gave rise to large 
mycelia, from which however no other spores were obtained : this 
matter was not followed up further. 
On living leaves of Carex the ascospores germinated freely, 
but although the small mycelia developed flask-shaped condio- 
phores, no infection was observed. 
It still remains to be decided whether the fungus is truly 
parasitic. 
Among the Uredinese may be mentioned Puccinia Andersoni, 
B. and Br. 3 , which I found on Garduus heterophyllus — itself an 
interesting plant, by the bye — in Yorkshire, forming dark violet 
or black patches on the leaves. 
Goleosporium Senecionis. 
This Uredine was collected in some quantity in its aecidial 
stage ( Peridermium Pini ) in the early summer in Norfolk on the 
needles of Pinus Laricio and Austriaca, and in its Uredo stage 
later in the summer, on Senecio sylvaticus growing beneath the 
same pines. Miss Dawson has successfully infected plants of 
Senecio sylvaticus and S. vulgaris with the secidiospores, and we are 
awaiting the results of the reciprocal infections of pine-seedlings. 
Infection experiments have also been made on other species of 
Senecio, the results of which will appear in due course : S. Jacobcea, 
S. erucifolius and S. aquaticus apparently refuse infection. 
Ncematelia encephala , Fr. 
Though by no means uncommon in the Scotch Pine-forests, 
this fungus is often overlooked and is by no means well known. 
I found it in abundance this last autumn on dead Pine-twigs, 
and cultivated it with some success. The basidia are divided by 
vertical walls, and my results fully bear out Brefeld’s 4 confirmation
