92 The Scottish N'atitralist. 



M. befuliua, /Ethaliitin sepiicum, Sepedoniiim chrysospermtun, Dothi- 

 dea geranii^ Ti'ichodenna viride, Septoi'ia stachydis, S. scab'ioscecola^ 

 Trtchobasis suaveolens, Epichlo'e typhina^ &c. On a bridge cross- 

 ing a ravine Cystopteris fragilis is abundant, and almost every 

 frond was covered with the rather local Uredo Jiliciim. On Vac- 

 ciniimi vitis-idcEa the curious Exobasidmm vaccinii was not un- 

 common \ and on leaves of Viola sylvatica and Geujn rivale^ 

 respectively, occurred Septoria violcE and S. get. The dark- 

 coloured Agaricus chalybczus was also found near the woods. 



Still further down the glen, where the woods become of a 

 varied character, there is another change in the fungi; and if 

 these woods were examined at the proper season there is little 

 doubt but that they would be found very prolific. On an oak 

 a magnificent example of the beautiful Polyponis sulphiireus 

 flourished for some time ; and under the shade of the trees 

 various species of Boletus were not uncommon, including B. 

 p achy pus ^ B. la?icinus, B. piper at us, and B. subtomentosus. On 

 the mountain - ash leaves Rcestelia coj'nuta was frequent, and 

 amongst other fungi noticed were Hygrophorus psittacinus, Gom- 

 phidius glutinosus, Russula i?itegra, Aga7'icus laccatus, Lactarius 

 volemen, Marasmius oreades, Asteivnia veronicce (on Veronica 

 officinalis), Sphcei-ella runiicis, Dichcena strobilina, Septoria ulmi, 

 Coleosporiuin campanulce. (on Campanula rotundifolia), Phrag- 

 niidiuni mucronatuin, Dothidea podagra7'ice, Dacrymyces deliques- 

 cens, Asteroma rosce, Erysiphe communis, &c. A few specimens 

 of a pale variety of Peziza cochleata were picked up near the 

 York Cascade, and on the hymenium of one of them was a 

 parasitic fungus, Bactridium acutuni. Passing the Castle, a little 

 time was spent in examining a small wood of spruce and other 

 trees near the highroad. Amongst other finds in this plantation 

 was Phclonitis strobilina on old cones of spruce, Polyporus annosus 

 on fir stumps, Stemonitis fusca and Lycogala epidendrofi, also on 

 stumps; and amongst the lurger fungi Lycoperdon ccslatum, Agari- 

 cus deglubens, Lactarius deliciosus, Phallus impudicus, Boletus 

 edulis, Spumaria alba, &c. 



In addition to the fungi I have enumerated, some others have 

 been found in Glen Tilt, such as Agaricus ostreatus, which was 

 found by Mr Keith some years ago. I have also omitted to 

 notice in their proper places a few that we found. Amongst 

 these are Paxillus leptopus, considered by some authors to be 

 a variety of P. involutus, Scptonema elongatispora, parasitic on 

 Geranium pratense and G. sylvaticum, Agaricus nigrellus P., Ag.
