106 MICEOSCOPIC FUNGI. 



the discovery of three specimens of a large Boletus 

 {B. cyanescens)/^ not founds to our knowledge^ since 

 the days of Sibthorpe^ was further enriched by a 

 species of Trichohasisy new to Britain^ and apparently 

 uncommon on the Continent. This rust was found 

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

 nassia iDahisiris) 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 

 early stages_, shortly stalked. We have called this 

 species Trichobasis Parnassice. It is possibly the 

 same as published by Westendorp in his ^^ Herbier 

 Cryptogamique Belge^^ as Uredo Parnassicey 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 Trichohasis and not 

 an Jlredo, 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 leading 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.
