 — C!. furcata *CI. diffissa Stirt., Not. Brit. Glad. (1885) p. 3. „Phyllo- 

 cladia basalia mediocria vel parva, crebriuscula. Podetia basi sim-

 axillae perviae, ramorum apices pervii infundibuliformes; apothecia 

 fusca, primum planiuscula, dein convexa, mediocria (latit. circiter 

 0,5 mm), interdum congesta. Goll. M'Andrew 90. It has entirely the 

 habit of a short rigid Gl. gracilis, more especially as the infundi- 

 buliform apices present very much the appearance of scyphi with 

 their coronae of apothecia. — CI. arborea Stirt., Not. Brit. Glad. 

 (1885) p. 4. „Phyllocladia basalia pauca laciniata. Podetia erecta, 

 infra simplicia vel rarissime semel divisa, robusta, brevia (alt. 

 0,5 — 1 poll.), superne incrassata, laevigata, esquamulosa vel basi 

 sqamulis parvis, paucis interdum vestita, scyphifera; scyphi irre- 

 gulares, margine radiato-ramosi, ramis fastigiatis et irregulariter 

 ramulosis, saepe repetito-ramulosis, apicibus infundibuliformibus 

 et fructiferis; apothecia fusca, mediocria. Ad terram Lochar Moss 

 prope Dumfries a cl. J. M'Andrew lecta (n. 113). This lichen 

 also has much the aspect of a state of Gl. gracilis but I fear all 

 the cups are perforated as in the preceding, at least ihe secon- 

 dary ones are so. It is certainly a very singular form."
