prominent, blackish, becoming convex; paraphyses thickish, 
septate, more or less coherent ; epithecium dark-bluish ; spores 
ellipsoid or subfusiform, 12-14 » long, 4-5 » thick; hymenial 
gelatine blue, the asci at length violet, with iodine.—Lecanora 
actea Nyl. in Flora lvi. p. 290 (1873); Cromb. in Grevillea ii. 
p- 89 (1873) & Monogr. i. p. 447 ; Knowles in Sci. Proc. Roy.

The specimens in the herbarium are too scanty to allow reexami- 
nation. Bouly de Lesdain describes a var. violacea (1. ¢.) with violet 
fimbriate hypothallus, smoky-brown epithecium, capitate paraphyses, 
spores 9-15 uw long, 5-6 p» thick, and shorter spermatia, 12-16 p» long, 
those of the species being 16-20 » long. De Lesdain considers that 
spermatia may vary considerably within the species, and he also 
suggests that L. actza, though seeming so different, may be a growth 
form of L. erysibe.

Differs from L. erysibe in the determinate thallus and in the 
apothecia, but very closely related to some forms of that species. 
The spermatia are 18-25 » long, °5 p» thick.

7. L. aipospila Th. Fr. Lich. Scand. p. 293 (1871).—Thallus 
suborbicular or spreading irregularly, composed in the centre of 
crowded angular or tuberculose papille, which are scattered and 
are smaller or flattened out towards the edge, greyish- or very 
dark-brown (K—), a dark hypothallus sometimes limiting the 
thallus. Apothecia small, innate in the papille, dark-brown or 
blackish, plane, becoming convex and immarginate ; paraphyses 
widening upwards, thickly-septate, brown at the tips ; spores ellip- 
soid, 9-14 p long, 4-6 p thick (or rather larger up to 16 p x 6»); 
hymenial gelatine bluish then dark-violet with iodine.—L. erysibe
