Spores ellipsoid-oblong, soleaform (2-locular) , brown. Ap- 
parently possesses pycnidia. 
8. A. Friesii, Hepp, 464. 
On thallns of Verrucaria chlorotica, Ach. 
Spores very small, soleaform (2-locular) , brown. • 
A. exilis, Flk., Hepp, 473 ; Mass., Rich., 88; and var. 
macrospora, Hepp, 473; is a Lecidea, with a proper thallns 
(Nyl., Prod., 136). 
A. arthonioides , Mass., Rich., 89, is also apparently a 
Lecidea (Fee). 
A. Ricasolii, Mass., Rich., 89 ; syn. Buellia, Korb., Par., 
189; has also a proper thallns, and grows on tree-barks. 
It apparently includes (according to Korber) Massalongo’s 
A. arthonioides and Fee’s Buellia arthonioides.

on various Peltidece and Solorince, Nyl., Scand. 
Spores 6 — 8, small, ovate-ellipsoid, 2-locular, colour- 
less. Possesses both spermogonia and pycnidia. A Lichen 
in so far as concerns the blue reaction of the hy menial ele- 
ments with iodine. If this plant is to be referred to the 
Lecideee, it will belong to that small section that possesses 
pycnidia in addition to spermogonia. 1 
2. S. Krempelhuberi, Korb., Par., 455. 
On Solorina saccata. 
Spores 8, very minute, ellipsoid, 2-locular, colourless. 
3. S. Stereocaulorum, Anzi (Korb., Par., 455). 
* Syn. Lecidea, Anzi. 
On thalline scales, or phyllocladia, (“ thallus-schuppen ”) 
of Stereocaulon tomentosum, v. alpinum, and S. fastigiatuni 
(Korb., Par.). But under the head Stereocaulon, in his 
‘ Parerga,’ Korber mentions neither a species nor variety 
fastigiatum ; nor does he mention it in his ‘ Systema/ 
Spores 8, small, acutely ellipsoid, 2-locular, colourless.
