248 DR. LINDSAY ON THE SPERMOGONES AND 
about the periphery. Spermatia and sterigmata are as in the type, or as in Lecanora 
subfusca, slightly more delicate and slender than in the latter. 
Specimen 18. Var. eleochroma. On bark of young firs and oaks, Switzerland: Hepp ' 
Exs. No. 3, sub Biatora olivacea (Nyl. Prod. p. 124). Outside the region of the apo- 
thecia, on the centre specimen in my copy, are numerous black, punctiform spermogones. 
The envelope is of indigo-blue or black cellular tissue. Spermatia are in myriads, atomic, 
ellipsoid or oval. Sterigmata are so short as to seem to be absent; they are appa- 
rently simple and linear. The spermatia and sterigmata are thus, it will be observed, 
very different in character from those of the type. 
Specimen 19. Var. enteroleuca, Ach. On barks of trees, Yorkshire, Oct. 1857: Dr. 
Carrington. Spermogones occur on pale smoothish patches of thallus, external to the ordi- 
nary form of thallus (dark and granulate), which is oceupied by the apothecia ; they vary. 
in size, from aes aes to distinct black papillee. Spermatia are vermiform (as in the 
type) about 4455 to 41259 long. Sporidia also are simple and oval, as in the type. 
Specimen 20. Var. enteroleuca. On stones, Shelong, Kumaon (13,000 ft.), Himalayas : 
in the herbarium of Strachey and Winterbottom, Kew, sub L. glacialis. "Thallus thick, 
tartareous, tawny-coloured. Spermogones and spermatia of the type. 
Specimen 21. On the bark of young beeches and oaks, Switzerland: Hepp Exs. 
No. 127, sub Biatora enteroleuca. In the centre and upper specimen in my copy, sper- 
mogones are abundant as papillar elevations of the thallus, tipped by black, stellate- 
fissured ostioles, scattered among the apothecia. Spermatia are thickish and much 
twisted, sterigmata subspherical, both as in the type. 
Species 9. L. TAYLORI, Salw. (Mudd, Brit. Lich. p. 199,— Beomyces anomalus, Tayl. Fl. 
Hib. p. 79,— var. anomala of L. parasema in my MS. notes, 1858). 
Specimen 1. On granite, Dunkerron, Kerry: named by Taylor himself in Herb. 
Mackay. Spermogones are abundant as irregular, roundish, pale, pellucid spots, (the 
bodies immersed,) scattered among the apothecia. Spermatia are abundant, curved, and 
twisted, as in Lecanora subfusca or Lecidea parasema, very delicate or filiform, about 
1300 X 30000 Sterigmata are simple, as in L. subfusca, about 1555 to 1455 long with 
spermatia attached. In other words, the spermogones and their contents are those of the 
type in L. parasema, to one of the many anomalous forms of which this lichen appears 
to me referable. 
Species 10. L. contors, Ach. (Mudd, Brit. Lich. p. 201; which appears to me but a saxi- 
eolous form of the protean L. parasema). 
Specimen 1. On red sandstone, Kerry: Dr. Moore in herb. Carroll. Associated with 
Verrucaria viridula. Thallus lemon-yellow, made up of a series of minute granules or 
scales aggregated into a thin tartareous crust, frequently sorediiferous or pruinose. 
Sperinogones occur on separate sterile patches of thallus, of similar colour, as immersed, 
round, or irregular ond spots, resembling those of Lecanora subfusca or L. varia. 
Spermatia are 15355 X 25559, on short, simple sterigmata. 
Specimen 2. On limestone, Yorkshire: Dr. Carrington. Apothecia at first flat, mar-
