inside the margin of the cap. Stipe 4—6 cm long, 1—2 cm thick, spongy 
inside, firm outside, greyish brown (h 4), here and there covered with greyish 
white adpressed hairs. Flesh pale with mealy odour and flavour. Gills 
fairly crowded, emarginate, often with transverse veins and anastomosing.

In the same place I have found T. panaeolum, but not T. aggregatum, 
I think it is doubtful whether T. aggregatum grows in this locality.

with watergrey spots forming zones, otherwise greyish brown and grey 
when dry. Stipe white, fibrous-floccose, cylindrical, stuffed, cartilaginous.

Cap c.8 cm broad, convex with a low rounded umbo, later crateri- 
form with or without an umbo, yellow or pale brown along the margin 
(ranging from k 3 to g 7), darker at the centre, smooth and greasy. 
Stipe 12cm high, 1—1.5 cm thick, increasing in thickness towards base, 
the upper part faintly sulcate and mealy, floccose, the lower part covered 
by white projecting hyphæ, the colour is greyish-brown (f 8); flesh of 
stem fibrillose finally becoming so soft that the upper part of the stem 
cannot support the cap, but bends at an acute angle, the cap becoming 
pendent. Gills c.12 mm broad, crowded, thin, yellow with a red tinge 
(b 6), deeply emarginate or almost free. Spores colourless, ellipsoidal or 
acuminate below, minutely verrucose-echinulate, 9X5 u. Cystidia lanceo- 
late, up to 60X12 u, bearing a lobate hood at apex. 
The yellow form of Rickens Tricholoma turritum (Fries) seems to 
be identical with this.
