prate?tse, which grows here and there on the banks of many of the 

 burns, including the Tilt itself. 



The mountain lochs have of course their own plants. In the 

 boggy ground surrounding them Bctula nana grows, and in the 

 water Isoetes lacustris, &c., as well as the curious Utriciilaria, 

 which, as I have seen no flowers, I can only suppose to be vul- 

 garis. Of the great genus Carex, few of the rarer species have 

 been found, the rarest being vaginata, which grows on Ben 

 Ghlo. Carex pauciflora is exceedingly abundant on many of the 

 hills. 



As for the ferns, nothing very rare occurs, the less common 

 alpine species, such as Polystichum lonchitis and Pseudathyrium 

 alpestre, being far from abundant. All the species of Lycopodium 

 except inundatuni may be found; and inundatum has been said to 

 occur near Blair Athole. 



The total number of flowering-plants and ferns occurring in 

 Glen Tilt amounts to nearly 350, which, all things considered, is 

 a very respectable allowance. 



In the concluding part of this paper the other cryptogamic 

 plants will be briefly noticed. 



Mycological Notes — Hypocrea riccioidea, B. — A most interesting 

 discovery has recently been made of the recurrence of a long-lost fmigus. 

 The plant, which was growing on dead willow, was forwarded to me in 

 April last by Mr James M 'Andrew of Nev/ Galloway, and proved to be 

 Sph(xria riccioidea. Bolt., or Hypocrea riccioidea. Berk. It appears that the 

 species has not been found in this country since February 1790. Mr Berkeley 

 has written a note on the subject to the 'Gardeners' Chronicle,' in which 

 he says — 



" Both the figure and description of Bolton are, as far as they go, excellent, 

 even to the greenish matter on the older portions of the fungus. It was found, 

 in the autumn of the same year (1790), by Tode, who gives a figure of it, 

 under the name of Ac7-osperma lic/ienoides, in his 'Fungi of Mecklenburg.' 

 Mons. L'Amy found it near Limoges, and a figure was given from his speci- 

 mens by Dr Montague, in ' Annales des Sciences Naturelles' for 1836, who 

 did not, however, identify it with the plant of Bolton. These, we believe, are 

 the only occasions on which this rare and interesting species has been found." 



To find a plant after so long a period, and thus to confirm previous obser- 

 vation, is a source of more genuine satisfaction to the Mycologist than even 

 the discovery of new species. Mr M 'Andrew has fortunately been able to 

 send me a sufficient number of specimens to admit of its being included in 

 the first fasciculus which will be issued by the Cryptogamic Society of Scot- 

 land. — John Stevenson, Glamis, May i^j^.
