Cups \ to 1 line broad. Asci 45-55 x 6-8 p. 
Mollisia (Pyrenop) lignicola, n.s. 
Gregarious or scattered, sessile, at first globose, at length some- 
what expanded, externally scabrous, and vertically rugose, brown 
or blackish-brown, when dry black ; margin sub-fimbriate from the 
slightly unequally elongated cells ; hymenium pallid ; asci 
cylindraceo-clavate ; sporidia 8, cylindrical or fusiform, obtuse, 
straight or curved, 5-8 x 1-5-2 p. Paraphyses indistinct. 
On old worked wood (on an old gate). Bagley Wood, Berkshire 
(1821) ! (Mr. Baxter.) 
Cups a line broad ; when dry collapsed, but not plane even 
when moist. Asci 35 x 4 p ; sporidia biseriate. The marginal 
cells have the form of short septate blunt hairs when highly 
magnified. 
Helotium badium, n.s. 
Gregarious, erumpent, sessile, at first turbinate and slightly 
concave, at length plane ; hymenium bay-brown, margin distinct, 
somewhat lighter, externally the same colour, glabrous ; asci 
broadly clavate, rather abruptly narrowed at the base ; sporidia 8,
