FETCH : 
It is evident from the available specimens and figures that 
these were mixtures, though it has not been possible to match 
them all with fresh specimens. Thwaites’s 712, however, is a 
very common species, which grows in troops round decaying 
stumps, following the lines of the lateral roots. It sometimes 
occurs in company with Psaihyra trechispora Fetch, which 
has the same habit ; but I have not been able to ascertain 
that the names quoted cover the latter species. It is not 
Psathyra obtusata. Thwaites’s figure, 712, represents poor, 
unexpanded specimens. 
The pileus is at first conical, then broadly conico-convex or 
almost plane, up to 6 cm. diameter, sometimes with a cönical 
umbo, bay-brown to ashy, darker in the centre, and when 
ashy, frequently with a purple tinge towards the margin, 
radially ridged with slightly elevated anastomosing ridges, 
sometimes atomate, sometimes with scattered, fioccose 
remains of a veil. The fiesh is thin and the pileus fragile. 
The stalk is up to 8 cm. long, and 8 mm. diameter, white, 
shining, brittle, sparingly fioccose, longitudinally striate, 
attenuated upwards, hollow. The gills are pallid, then purple- * 
brown with a white edge,* crowded, adnate, subventricose, 
up to 7 mm. broad. They bear fusiform or fiask-shaped 
cystidia, 40-50 high, 16-20 ^ at the widest, with the wall 
strongly thickened at the apex (up to 8 ^ thick) and thinning 
off along the sides just below. The spores are purple-brown, 
narrow-oval or oblong-oval, inequilateral, 6-7 X 4 pi.. It may 
be known as Psathyra reticulata. 
Psathyra reticulata, — Pileo primo conico, deinde late conico-
