FLORA OF RRITISH FUNGI. 
The other species which finds a place in the above work as — 
Agaricus (Stropharia) obturatus, Fr. (see page 311), to illus- 
trate which reference must be made to Bresadola’s “ Fungi Tri- 
dentini,” part iv-v, pp. 56, whence it is clear that Fries, as in 
some other instances, failed to appreciate correctly the species 
figured byBulliard, and hence the three consecutive Ag. coronillus , 
Ag. obturatas, and Ag. melaspermus are confused and mixed up. 
This will be elucidated a little by reproducing Bresadola’s obser- 
vations, as published, leaving “ scholars to examine and compare 
the descriptions in the original language.” 
Stropharia melasperma, Bull. f. 540 ; Quel. Jur. t. 24, f. 3 ; Bres. 
Trent, t. lxi. 
Pileus carnosus e convexo planus, subdepressus, mollis, laevis, 
viscidulus, mox siccus, saepeque epidermide areolato- diffract a, 
albidus, centro stramineus 3J-4| cm. latus ; lamellae confertae, 
ventricosae, postice . sinuato-adnatae ex albido violaceo-cinereae, 
demum cinereo-nigricantes ; stipes albus, farctus, subaequalis, e 
sericeo-fibrilloso glabrescens, apice striatus 4-6 cm. longus 6-7 
mm. crassus ; annulus albus, stipiti adhaerens, supra dimidium 
striato-sulcatus, infra laevis, deciduus. Caro pilei alba, stipitis 
demum substraminea vix odora. Sporae in cumulo compacto 
fuscae, sub micr. fuscidulae, ovoideae 10 X 6 mmm. ; basidia clavata 
22-28 X 8 mmm. 
Aestate, autumno. Locis herbidis, pascuis etc. raro. 
Fungus hicce in Europa boreali haud videtur obvius ; nam 
species, quae sub hoc nomine a Fries in Monogr. i, p. 413, Icon. 
Select, t. 130, f. 2, et Hymen. Europ., p. 285, describitur et pin- 
gitur, nihil aliud est quam Stropharia coronilla, Bull. Genuina 
Stropharia melasperma, Bull., neque pileo ochraceo, neque 
lamellis purpureis gaudet, prouti Fries suum Ag. melaspermum 
describit ; hae notae e contra Ag. coronillo , Bull., conveniunt, 
cujus, ut melius in posterum distinguatur, hic novam diagnosim 
simul cum synonimia exhibemus.
