116 LICHENOLOGICAL MEMORABILIA,

We next day went by rail to Portmadoc, and there took a car 

 to Beddgelert. The adjoining town of Tremadoc would be a 

 capital place to sojourn at for the botanical exploration of the 

 neighbourhood, the rocks and woods skirting the road to Bedd- 

 gelert being grand and sublime in the extreme, with mountains 

 of considerably height and promise in the distance. Indeed, this 

 is the route the tourist should take to see the Pass of Aberglaslyn 

 in its grand sublimity, the return from Beddgelert to Tremadoc 

 being comparatively tame. 



Arrived at Beddgelert, we walked to the Lake Llyn Dinas, and 

 on the rocks flanking its shores ioxxwiMiamalina suhfarinacea,'^Y'L., 

 Lecidea stellulata, Tayl., L. rivnlosa, Ach., y. obscurior, Crombie, 

 and a curious variety of Lecanora cinerea, (L.), with the aieolje 

 elevated into convex squamula?, and which I have consequently 

 named var. lepidota. The same state I have previously possessed, 

 unnamed, from Jersey and from Barmouth, On the trees we only 

 found Arthonia vinosa, Leight. var. inneti, Korb. ; Afthonia 

 Swartziana, Ach. ; and Venncaria ejndermidis, Ach., var. fullax, 

 Nyl. 



Returning homewards, we stayed an evening at Barmouth, 

 and there gathered, in Mr. Salwey's original locality, good specimens 

 of Lecidea Taylori, Salw., Lecidea jur ana, Sch^er., and Pyrenopsis 

 fnscatula, Nyl., is a single specimen. 



I had nearly forgotten to mention that the last day of our stay 

 at Trefriw was rendered memorable by the fortunate discovery 

 by my friend and companion, Mr. Wm. Phillips, on the soil and 

 decaying Jungermannife of a broken roadside bank of Tlulocarpon 

 sv2)erellwn, Nyl., and of a new fungus, a Periconia, which Mr. 

 Berkeley has named Periconia Phillipsii ; a well-merited and 

 deserved compliment to its discoverer, whose talents are now so 

 well and so far known as an ardent, enthusiastic, and scientific 

 student of British Fungi.
