FUNGI. 
as being externally “ Ex albiclo-luteola, marginibus ochraceis, disco 
laete fulvo-ochracea , demumque badio-fulvo.” Rehm has the same 
species in view as Bresadola, and in the comments of his Ascom., 
Fasc. xiv., in “ Hedwigia,” 1883, p. 34, has “652, Otidea auricula 
(Cooke sub Peziza) ; cfr. Cooke Mycogr., PI. 54, f. 213 (“ Farbe 
der Perithecien etwas zuhellbraun ”). Rehm evidently considers 
that his fungus is the same as Cooke’s, but that the latter differs 
in being the same colour all over. A few lines further on Rehm, 
in giving the synonymy of his supposed Otidea auricula , says, 
“ Minime, Cooke, f. Brit., i., 473 (Jod intensive f),” hence we see 
that Rehm accepts Cooke’s figure of Otidea auricula , but rejects 
the specimens from which the figure was drawn. If either 
Bresadola or Rehm had made a comparative examination of the 
tissue of Cooke’s fungus with their own they would have found out 
at once that they were dealing with two distinct species. Finally, 
Otidea auricula , as understood by Cooke and described above, is 
characterized by being everywhere yellowish-brown ; excipulum 
parenchymatous, cells very large ; paraphyses clavate, straight, 
equal in length to the asci. Among near allies 0. onotica difters 
in the smaller spores, 0. leporina in the paraphyses being curved at 
the tips ; and the somewhat distantly allied fungus, confused by 
Bresadola and Rehm with the true 0. auricula — which may be 
called Otidea neglecta — is sharply distinguished by the bay brown 
disc, and the excipulum consisting of densely interwoven septate 
hyphse that become arranged in a parallel series towards the 
outside. 
Otidea neglecta, Mass. 
Gregarious, coriaceous and tough, constantly hare’s-ear shaped, 
narrowed downwards into a short, usually grooved whitish stem- 
like base ; margins at first involute and approximate, then ex- 
panding and becoming sometimes almost plane, rigid when dry, 
4-7 x 3-5 cm. ; disc deep tawny-ochraceous or bay-brown ; ex- 
ternally whitish, with a tinge of yellow or ochraceous ; excipulum 
composed of hyaline, sparsely septate, and densely interwoven 
liyplue (4-6 p thick), which run out to the circumference as parallel, 
closely packed, septate, obtuse, subclavate liyphae, 10-14 p diam. ; 
asci cylindrical, narrowed at the base into a flexuous pedicel ; 
8-spored ; spores obliquely 1-seriate, smooth, hyaline, continuous, 
usually 1-guttulate, elliptical, ends obtuse, 18-24x12-14 p ; 
paraphyses straight, septate, apex clavate, brownish, 6-8 p 
diam.
