Sphcerulina taxi (Cke.) ; in the genus Sphcerella, as understood 

 at the present day, the spores are i -septate. 



In a damp corner of Potridings Wood a large patch of 

 Ground Ivy (Glecho?na hederacea) illustrated very clearly the 

 meaning of an epidemic caused by a parasitic fungus, nearly 

 every leaf showing several chalk-white blotches caused by 

 a minute mould — Ramularia calcea Cesati. Parasitic moulds, 

 mainly Erysiphe, were very prevalent throughout the dis- 

 trict. They were seen on Arctium lappa, Polygonum aviculare, 

 Acer, Circcea lutetiana, Heracleum sphondyliuni, Hypericum hir- 

 sutum, Trifolium repens, T. pratense, and Alchemilla vulgaris. 

 Some special moulds even attack other fungi, especially Agarics; 

 every specimen of Clitocybe fragrans looked at was the host of 

 Sporodinia aspergillus Schrcet. = Syzygites megalocarpus Cke. 



Special attention was paid to host plants and habitats of 

 fungi observed for the purpose of recording in the List of 

 Yorkshire Fungi,' in course of preparation for publication. 



In Melton Woods about a dozen specimens of Tricholoma 

 leucocephalum were found growing clean through the flattened 

 remains of a dead Hedgehog. They were exclusively confined 

 to this small area, and were in all stages of development. 

 Presumably this covering had favoured the germination of the 

 spores in the ground beneath and helped on the formation of 

 a succeeding generation of basidiophores. 



Permission had been obtained to visit Edlington W T oods, but 

 so much attention was given to searching for micro-species that 

 time was not available. Micro-material was found in sufficient 

 quantity to keep four microscopes in full employ in its examina- 

 tion during the evenings and early mornings. Much of it 

 required attending to with as little delay as possible. 



Several novelties were found in a heap of decaying grass 

 near Cadeby. One new to science = Splice rode rma giganteum 

 Mass.&Crossl. ; Chcettomium murorum Wint.; and Arachnomyces 

 u/lidus Mass. &Salm. The latter species is the type of a new 

 genus discovered at Kew by G. Massee and E. S. Salmon, some 

 short time ago, the diagnosis of which is in the printers' hands 

 at the present time. 



The rabbits' dung wherever it was seen was plentifully pitted 

 and decorated with numerous species of fungi of one kind or 

 another, though very often S/ilbum fimelarium monopolised the 

 whole pellet. This dung yielded a fine specimen of Poronia 

 lepbrina Ellis & Everhardt. This species is new to the European 

 Flora, being previously only know n from the United States,
