108 ON SOLORINA BISPORA. 



wet season had served to stimulate the conglomerated gonidiac 

 granules into renewed activity, and produced (along with the con- 

 sequent maceration) the modified thallus in question. 



Had time and space permitted, I should have liked to have en- 

 larged somewhat more on this subject ; meanwhile, I shall content 

 myself with describing a genuine parasite on S. bispora, viz : — 



Lecidea epiphorbia, Stn. — Apothecia resemble, externally and 

 internally, those of L. Parmeliarum, except that the paraphyses 

 are neither thickened nor darker coloured at their apices, the spores 

 are colourless, or present in a few instances, a faint tinge of yellow, 

 and the reaction on the gelatina hymenia by means of iodine, 

 shows a deep vinous red without any preceding caerulescent tint, 

 instead of being negative, as in L. Parmeliarum. This lichen 

 bears the same relationship to L. Parmeliarum that L. solorinaria 

 does to L. oxyspora.
