26. LEMMOPSIS A. Zahlbr. in Engler & Prantl Nat. 
Pflanzenf. i. 1*, p. 171 (1906). Leptogium sect. Lemmopsis 
Wainio Lich. Brésil i. p. 221 (1890). (PI. 26.) 
Thallus effuse, thin, granular-crustaceous, corticated. Algal 
cells Nostoc. Apothecia sessile on the thallus, with a proper 
margin ; spores ellipsoid, colourless, simple. 
The corticated thallus agrees with that of Leptogiwm, but the 
habit of the genus, and the spore characters are different. 
1. L. Arnoldiana A. Zahlbr. 1. c.—Thallus effuse, thin, 
granular-crustaceous, scattered, olive- or dark-brown. Apothecia 
small, somewhat prominent, with a proper margin, reddish or 
dark-red, the margin paler ; paraphyses slender, septate; spores 
ellipsoid with granular oily contents, rather large, 17—20 p long, 
5-7 » thick; hymenial gelatine slightly bluish then pale wine- 
red with iodine.—Physma Arnoldiana Hepp. ex\Arn. in Flora xli. 
p. 94 (1858). Collemopsis Arnoldiana Nyl. in Flora lvii. p, 305 
(1874); Cromb. in Journ. Bot. xiv. p. 359 (1876) & Monogr. i. 
p. 79; Leight. Lich. Fl. ed. 3, p. 36. 
Usually forming a thin dark-coloured crust on the stones; the 
waxy-looking apothecia are usually numerous and distinctive. 
Hab. On calcareous stones in shady inland situations.—Distr. 
Apparently local and rare in 8. and W. England.—B. M. Cowcombe 
Wood near Chalford, Gloucestershire ; Gomshall and Shiere, Surrey. 
2. L. oblongans A. L. Sm.—Thallus effuse, thin, minutely 
- granular, and continuous, brownish-olive." Apothecia small, 
reddish or yellowish-red, the margin rather thick and con- 
nivent ; paraphyses slender; spores oblong, elongate, simple 
(or spuriously l-septate), 16-30 » long, 6-7 » thick ; hymenial 
gelatine faintly bluish then slightly wine-red with iodine.— 
Collemopsis oblongans Nyl, in Flora lvii. p. 305 (1876); Cromb. 
in Grevillea iii. p. 22 (1874) & Monogr. i. p. 79; Leight. Lich. 
Fl. ed. 3, p. 36. 
Resembling the previous species in the structure of the thallus, ° 
but lighter in colour and with larger spores. 
Hab. On the ground in shady crevices of limestone rocks.—B. M. 
Haverbrack Hill, Westmoreland (the only locality).
