NEW DISCOMYCETES FROM ORKNEY. 
By William Phillips, F.L.S. 
THE following species have been detected among some of the 
material collected by Professor Trail in Orkney, in August, 
1888, which I had set aside for further examination. 
(All measurements, unless so stated, are in micromillimetres.) 
Hymenoscypha Symphoricarpi, n. s. 
Scot. Nat. 1889, p. 139, No. 105, as Hyjiienoscypha mirea (Pers.). 
Cups scattered, stipitate, cupulate, then expanded, plane, gla- 
brous, or minutely tomentose on the sub-bulbous slender stem ; 
margin entire ; bright yellow throughout ; asci cylindrical, nar- 
rowed at the base ; sporidia oblong or oblong-fusiform, rather 
obtuse, a gutta at each pole ; paraphyses filiform, slender. 
On dead branches of Symphoricarpus racemosus, Binscarth. 
Cups 300-500 broad, stem 300-1000 long; asci 60 x 7. This is 
a slender delicate species, which does not agree well with any 
described species. It comes near Phialea vitellina (Rehm.) Sacc, 
but differs in the sporidia, and tomentose sub-bulbous stem. 
Mollisia (Pyrenopeziza) Carduorum (Rthm). 
Fyrenopeziza Carduorum Rehm., Ascom. No. 68 ; Winter, in 
Flora^ 1872, p. 526 ; Saccardo Syll. Fung., Vol. VIII., p. 359. 
On Carduus lanceolatus, Binscarth. 
" Cupulis dense gregariis v. sub-confluentibus, sessilibus, extus 
glabris, papillatis, opaco-nigro-fuscis, basi pilis hyalinis repentibus 
cinctis, primo globosis, margine incurvo, papillato-crenato fim- 
briatove, demum difformibus, apertis, planis, fere emarginatis, 
disco piano incano-glauco, •5-1*7 mm. latis ; ascis cylindraceis, 
sessilibus, 8-sporis, 50-65 x 7 ; paraphysibus simpHcibus filiformi- 
bus, hyalinis ; [sporidiis lanceolatisj, rectis v. curvatis, 4-8-nu- 
cleatis, 12719 x i -5-2. 
" In cauhbus putridis carduorum in Franconia," W^inter, I.e. 
Mollisia (Niptera) cinerella, Sacc. 
forma caespitosa, mihi. 
On decorticated wood of Fagus syivatica, Binscarth. 
The cups break out in csespitose heaps : the sporidia are 
clavato-fusiform, and are furnished with a gutta near the ends. 
Lachnella orbicularis, n. sp. 
Minute, scattered, erumpent, sessile, orbicular, when dry black,
