NEW OR CRITICAL BRITISH FUNGI. 
Clavaria (Syncoryne) dissipabilis, Britz. 
Solitary, or usually in small clusters, but quite distinct at the 
base, simple, elongato-clavate, and tapering downwards, apex most 
frequently quite obtuse and rounded, rarely subacute ; circular, or 
not unfrequently compressed and channelled, otherwise even and 
glabrous, clear, deep orange -yellow, not becoming powdered with 
the spores, solid, collapsing, fragile ; 3-7 cm. high, 2-4 mm. thick 
near the apex ; spores globose, with rather long scattered spines, 
colourless, or with a tinge of canary yellow, 5-6 diam. (excl. 
spines). 
Clavaria dissipabilis , Britzelmayr, Hym. aus Sudb., Clavariei, 
p. 289, fig. 28. 
Among short grass in pastures, roads in woods, etc. 
A very distinct species, not at all uncommon, and previously 
mixed up with C. fragilis , from the yellow form of which it differs 
in the deeper orange colour and spinulose globose spores. The 
usual form is clavate and obtuse above, becoming narrowed into a 
slender stem. 
Halifax. (C. Crossland.) Specimens are in the Kew Herbarium 
under C. fragilis , from Lyndhurst, Kew, Coed Coch, and near 
Edinburgh. 
Gyrodon rubellum, McWeeney . 
Pileus 1-IP cm. across, convex, even, smooth, dry, red, with a 
tinge of purple at the disc, becoming yellowish towards the 
margin ; flesh firm, yellow, not changing colour when broken ; 
pores about 1 mm. long, pale yellow, openings linear, elongated, 
sinuous, dissepiments thick, edge bright yellow ; spores cylindric- 
fusiform, with a minute oblique basal apiculus, greenish olive, 
10x4 /a; stem 1 cm. long, 3 mm. thick, equal, smooth, even, 
solid, bright yellow, as is also the flesh. 
A minute, but very distinct species, and quite mature, as shown 
by the abundance of coloured spores. 
Among moss on the ground. 
Powerscourt, Dublin. (Dr. McWeeney). 
QUELETXA, Fries. 
Peridium subglobose, wall rather thin, even, glabrous, rigid, 
fragile, and breaking away in irregular patches at maturity, com- 
posed of a single layer except at the base, where it is double ; the 
inner basal layer, which extends upwards as a slightly convex 
columella, elongates downwards into a long stem, bursting through 
the outer layer, which forms a loose, torn sheath round its apex ; 
gleba forming a powdery mass at maturity, capillitium present ; 
spores borne on tetrasporous basidia. 
Queletia, Fries, Ofvers. Vetenskaps-Akad., 1871, p. 171, pi. 4. 
The present genus was established by Fries for the reception of 
a gastromycetous fungus discovered in France by Dr. Quelet. The 
peridium in very young specimens is continuous and homogeneous 
above, but double below, the outer layer is protective, and simply
