etnpetri grows here and there on Empetrum nigrum. On An 

 Scarsgach, above 2000 feet, Vibrissea inargarita occurred sparingly 

 on dead heather sticks in a spring. It has also been found in 

 Glen Tilt a few miles below Forest Lodge, and is probably not 

 uncommon in springs and small streams. 



Below 2000 feet, but above 1500, the above species are joined 

 by others, including Aga7'icus rimosuSj Ag. i^tfundibuliformis^ 

 Ag. (Bthiops^ Hygrophorus coniciis, Boletus scaber (amongst the 

 heather near Falar), Fuccinia Andersoni, F. violarum, Uromyces 

 appendiculata (on Lathyrus inacrorhizus — Uredo or obi DC), U. 

 apiculosa (on Tiifolium repens— Uredo trifolii DC), Ustilago 

 urceoloi'uin (on various Carices), Coleosporium pingue, and C. 

 tussilaginis. Most of these occur on the hill above Forest Lodge, 

 where also I have found ^cidiuin orobi on Lathyrus maawhizus, 

 yEc. trifolii repentis Kl. on Trifoliiun .repens, Ustilago utriculosa 

 on Folygofiuni viviparum, and Dactylium spirale on the leaves of 

 the same plant. Near Loch Tilt Venturia atramentaria may 

 be found on dying leaves of Vaccinium iiliginosum ; Fuccinia 

 bistortcB is common on leaves of Folygonum viviparum in many 

 parts of the Glen. Fuccinia luzulce has been gathered very spar- 

 ingly on leaves of Luzula multiflora in one of the ravines of 

 Ben Ghlo, and Isothea rhytismoides occurs on leaves of Dryas 

 on Craig Mb or. 



From the level of Forest Lodge downwards, fungi increase in 

 numbers. Underneath the shade of the fir-trees that grow near 

 the Lodge, Agaricus vaginatusx^ not uncommon, and Ag. rubescens 

 (a good esculent species) is not rare. The common mushroom 

 {Ag. cainpestris) also grows near the Lodge. On the banks of 

 the Tilt the Mountain Sorrel, Oxyria reniforniis, is not a scarce 

 plant ; and on various tufts of it beween the Lodge and Dal-an- 

 Eas Bridge, the very local and rare Ustilago vinosa abounds. 

 Whether it is always to be found there I cannot say, but I have 

 found it two years in succession. On Galium verum, near the 

 river, I have found ^Ecidium galii in small quantity. Here and 

 there Dactylium modestum is by no means unfrequent on Alchemilla 

 alpina. 



On a peaty bank near the kennels Agaricus mutilus, a rare and 



beautiful species, grows in small quantity ; and near the same 



place various other fungi, including Sphoirothcca pannosa, 



Ustilago antherarum (on Stellaria graminea)^ Fcziza granulata, 



Uredo bifrons, Agaricus campanulaitis, Coprinus plicatilis, Cor- 



tinarius violaceus^ Boletus chrysenteron, Triphragmium ulmaria;,
