CHLOROSPLENIUM. 287 



then 1-septate ; paraphyses slender, hyaline, very slightly 

 thickened upwards. 



On decorticated wood. 



The first knowledge of this species was obtained from 

 specimens received from New Zealand, shortly after which 

 it was found growing on an old Eobinia trunk in Kew 

 Gardens. Known from all other species by the constantly 

 regular, discoid apothecium, the brown .disc, and the 

 1-septate spores with acute ends. The wood on which the 

 fungus grows is stained verdigris-green, as in C. aentginosum.

 p. 102 ; Phil., Brit. Disc., p. 146 ; Sacc., Syll., viii. n. 1315. 



Scattered, shortly stipitate or only narrowed below into a 

 short, stem-like base ; closed at first, gradually expanding, 

 usually more or less irregular and wavy, glabrous; disc 

 yellowish olive or dingy green, externally purplish brown, 

 minutely wrinkled, 13 cm. across, tough ; hypothecium 

 and excipulum brown, formed entirely of closely interwoven 

 hyphae, 3-4 p. thick ; asci narrowly cylindric-clavate, tips 

 slightly narrowed, 8-spored ; spores irregularly 2-seriate, or 

 sometimes almost 1-seriate, hyaline, 2 4-guttulate, cylin- 

 drical, ends blunt, straight or usually slightly bent, con- 

 tinuous at first, then 1-septate, 9-12 x 3 '5-4 p.; paraphyses 

 slender, about 2 p. thick at the yellowish brown tips.

Coryne versiformis, Eehm, Krypt.-Flora, Disc., p. 492. 



On fallen fir-trunks, also on scales of fir-cones, and Phillips 

 says on ash-stumps. 



Distinguished from C. aeruginosum by the purplish exterior 

 of the ascophore, larger 1-septate spores, and by not staining 

 the wood on which it grows, green.

Chlorosplenium elatinum. Mass. 

 Ascophore stipitate, turbinate, at first closed, then ex- 

 panding, but the margin persistently strongly incurved 

 when dry, glabrous, somewhat shining, dingy blackish- 

 olive, 2-5 mm. across ; stem blackish, 2-3 mm. long ; 

 hypothecium and excipulum composed entirely of aseptate, 

 hyaline, branched, intricately interwoven hyphae, which
