Additional Notices to some of the Specimens placed in the Collection 

 last year. 



No. 337 I do not think Nylander has admitted Thelidium ; he con- 

 siders this plant a Verrucaria. The apothecium is deeply 

 seated in the stone, in age only exhibiting its upper portion ; 

 paraphyses none ; spores brown, muriform, and variously 

 septate; -0015" by -0006", hymenial gonidia abundant. It 

 must be admitted the plant approaches Verrucaria hymenogo- 

 nium (a plant not yet detected in Ireland). The asci are very 

 fugitive, and the spores are only seen escaped. The asci 

 which are visible contain only spore-matter, not formed 

 spores. Iodine eventuallv produces shades of dull purple.
