358 NOTES ON THE LICHENS IN SOWERBY'S HERBARIUM. 
6. Lichen ciliaris, E. B. t. 1352,— Physcia ciliaris (Linn.), typical, 
and f. actinota, Ach.—The specimen drawn from Bedfordshire (Mr. 
Abbot) will on reference to the fig. be seen to have some of the apothecia - 
with the margin smooth, and others with it proliferous. To this latter 
Acharius gave the name of actinota, but as the margin thus varies in one 
and the same specimen, as is usually the case in Britain, it is evident that 
at ha 
so-called var, verrucosa, Ach., which is Spir the type in a substerile 
eondition, with numerous elevated spermogones. 
. Lichen pulverulentus, E. B. t. 2063 Figs pulverulenta, var. 
laciniolata, mihi.—The figure has been referred by Nylander in Syn. p. 
421, as aiko by Leighton in Lich. Fl. p. 147, to var. venusta (Ach.). 
The specimen drawn, however, from Cambridge (Relhan), does not alto- 
gether correspond with the characters of the above var. Not only has it 
the margin of the apothecia crowned with the short horizontal laciniole, 
which are the distinguishing characteristic of venusta, but it has these also 
scattered over the thallus, as is well shown in the middle fig., where 
they are also somewhat ascendin : The are Boda age young leaflets in
