106 MICEOSCOPIC FUNGI. 



the discovery of three specimens of a large Boletus 

 (B. cyanescens),^ not found_, to our knowledge^ since 

 the days of Sibthorpe, was further enriched by a 

 species of Trichobasis, new to Britain^ and apparently 

 uncommon on the Continent. Tliis rust was found 

 on the leaves of the ^^ grass of Parnassus ^' {Par- 

 nassia jpalustris) on a narrow strip of marsh near 

 Irstead church. It was sought in vain elsewhere. 

 The leaves were scarcely changed in appearance, 

 except by the presence of the pustules. There were 

 no discoloured spots, but the pustules appeared 

 sometimes plentifully, more often scattered, on both 

 surfaces of the leaves : they were small, of a bright 

 brown, with oval spores ; the latter were, in their 

 «arly stages, shortly stalked. We have called this 

 species Tricliohasis Parnassice. It is possibly the 

 same as published by Westendorp in his '' Herbier 

 Cryptogamique Belge^' as Uredo Parnassicej but we 

 know of no copy which we can consult, and have 

 failed in discovering any other species to which we 

 can refer it. It is certainly a Tricliohasis and not 

 an Uredo J according to the present limitation of the 

 latter genus. 



Although the evidence against the retention of 

 the species of Lecythea (as the genus is named) 



* Two of these specimens were found at the bottom of a 

 hedge-bank, amongst grass, by the side of the road leadmg from 

 Neatishead-street to Irstead Eectory, and the third in a similar 

 position by the Norwich road, two hundred yards from the 

 turning which leads to Neatishead-street.
