*No. 93. — Verrucaria glaucina (Ack). Sheepwalk, Armagh. T. J. 



Dr. Nylander lias not noticed this form in 

 his "Expos. Synop. Pyren." Mr. Mudd 

 considers it as a variety of F. fuscella.* 

 The form, however, is constant, and is 

 found in Devonshire and Kent.

By thallus this plant is distinct from 

 V. maura and V. mucosa. As small por- 

 tions of No. 312 are seen on this speci- 

 men, the difference also between Nos.

 lus of this plant is cartilaginous; the 

 apothecia prominent, almost papillate ; 

 paraphyses none ; spores 8 in each ascus, 

 •0003" by •0002 // . Iodine has little 

 effect, causing only a slight yellow.

station, Co. Down. T.J. 

 Nylander has seen this plant, and pro- 

 nounces it as here named, f 



*No. 11. — Verrucaria mucosa (Wahlb.). Eocks seldom uncovered, ex- 

 cept at spring tides, Co. Down. T. J.

 tb alius, very conspicuous. Named by 

 Dr. Nylander. The specimen shows 

 both forms of fructification.
