SOME NEW BRITISH DISCOMYCETES. 
Fusiform, uniseptate, stylospores on slender filaments are abun- 
dantly intermixed with the asci and paraphyses, the summits rising 
a little above the surface of the hymenium. 
Patellaria Bloxami , Berk, in Bloxam’s collection in Kew Herb. 
On dead wood. No habitat is given. 
Cups about 1-4 lines broad. When dry the plant is black; the 
purple-brown colour of the interior is only seen in a microscopic 
section. The stylospores appear to arise from the sub-hymenial 
tissue, and are by no means an accidental addition, for they are 
present in all the cups I examined. They are similar bodies to 
those in Peziza diplocarpa, Currey, and cannot be explained as 
spores that have germinated. On the very young cups a few short 
hairs occur. The cells of the pseudo-pyrenchyma are about 7-5 /x, 
across. 
Dermatea Fagi, n.s. 
Erumpent, the orbicular or elliptic groups 1-8 lines across, 
splitting the epidermis ; cups plane or slightly convex, mostly im- 
marginate, when moist orange yellow, when dry ferruginous 
yellow, pruinose, densely crowded on an evident stroma ; stem when 
present stout, continuous with the stroma ; asci broadly clavate ; 
sporidia elliptic or oblon go-elliptic, filled with coarsely grained 
protoplasm, sometimes becoming rauriform, 18-23 X 0-12 p ; 
paraphyses slenderly filiform, abundant. 
Stylospores oblong- elliptic or elliptic, 10-20 X 7-9 p\ produced 
on the surface of the stroma in tufts between the cups on clavate 
sporophores. 
On Fagus sylvatica. New Aberdeen ! 1886. 
The cups are a line broad. The conidia are produced in such 
a quantity that they form a pale layer on the stroma, visible by the 
aid of a pocket lens ; I am not aware that they have been observed 
before in any other species. 
Name, from the name of the tree on which it grows. 
Cenangium seriatum, Fr. 
Gregarious or caespitose, erumpent through narrow transverse 
cracks in the bark ; cups globose- depressed, at first closed, at 
length opening, horny, black, glabrous, arising, in company with 
the Pycnidia and Spermagonia, in a linear series from a thin black 
stroma ; asci broadly clavate ; sporidia 8, linear lanceolate, acute 
at the ends, straight or curved, pseudo-multiseptate, 55-85 x 2-3 p. 
Spermogonia in the form of minute depressed tubercles, dis- 
charging by a pore the filiform-lanceolate spermatia, which are 
curved and about 15 p long. 
Pycnidia minute, slenderly conical, discharging by a minute 
apical pore the linear lanceolate stylospores, which are acute at the 
ends, curved, and about 30 p long.
