A plant variously referred by authors to Lichens or to Fungi. If 

 the thallus, as described above, be proper, it belongs to the former as 

 it contains gonidia. When the thallus is absent, often there is 

 sparingly visible a soft fungoid mycelium, which woTild seem to 

 indicate that it is a Peziza. It is retained here from its apparent 

 aflSnity to other species of Biatorella. The spermogones, con- 

 colorous with the apothecia, sometimes occm: by themselves, when 

 they are known as Sjahwria resincs Fr. 



Hab. On resinous bark and decorticated trunks of firs in hilly and 

 mountainous districts. — Distr. Seen from only a few scattered 

 localities in Great Britain ; not recorded from Ireland. — B. M. Shiere,

5. B. diflFormis Wainio in Helsingf. Faun. & FI. Fenn. Medd. 

 X. p. 143 (1883).— Thallus indistinct or absent (K-, CaCl-). 

 Apothecia small, at first concave and thinly margined, becoming 

 slightly convex and immarginate, black, opaque, concolorous 

 within ; paraphyses discrete ; epithecium and hypothecium brown ; 

 spores globulose, 0,0020-25 mm. in diameter ; hymenial gelatine 

 and asci deep-blue with iodine. — Peziza difformis Fr. Syst. Mycol.

Differs from the preceding in the colour of the apothecia and 

 iypothecium and in the rather smaller spores. The thaUus, described 

 by Leigbton as being brownish, greenish-brown, or purplish, is 

 evidently foreign; it grows intermixed with B. resince. The sper- 

 mogones, not imfrequent, are black. 



Hah. On resinous bark of firs in upland wooded districts. — Distr. 

 Seen from only two locaUties in England and Wales; no doubt 

 lio be detected elsewhere.— B. M. Shiere, Surrey; Bettws-y-Coed, 

 ■Carnarvonshire.

 greyish-black, areolate, the areolse blackish or yellowish-copper- 

 coloured, plane, angular, somewhat shining, radiate-plicate at 

 the circumference, hypothallus brownish-black. Apothecia minute,
