138. — Lepiota alborussea B. & Br. 
ILEUS up to 5 cm. diameter, almost plane, depressed or 
JL obtusely umbonate, sometimes with a depression in the 
umbo, deep reddish-purple in the centre, elsewhere radially 
streaked with reddish-purple, sometimes broken into minute 
scales. Flesh white, turning reddish under the cuticle when 
cut. Stalk up to 5 cm. high, 5 mm. diameter in the middle, 
inflated at the base, attenuated upwards, usually curved 
below, white, shining, stuffed, then hollow. Ring ascending, 
white, edge slightly coloured. Gills free, white, rather 
crowded, subventricose, rounded at both ends. Spores white, 
oval, somewhat pointed at the distal end, 7-9 X 3-4 
In flower beds, Peradeniya. 
139. — Lepiota erythrogramma B. & Br. 
Under this name Berkeley and Broome placed four of 
Thwaites’s figures, dividing them into the species and two 
varieties. Figure 1202 was named Lepiota erythrogramma, 
figure 1187, var. b, and two figures, both numbered 1159, var. c. 
Figure 1202, the type of Lepiota erythrogramma, does not 
differ from Lepiota alborussea. Berkeley and Broome appa- 
rently noted the resemblance, for they stated that L. alborussea 
differed in the breadth of its spores. As the specimens are 
not in Herb. Peradeniya, I am unable to test that statement, 
but the character does not appear to be one on which to found 
a species. I find the spores of L. erythrogramma var. b, 
6-7 X 3 [K, and those of L. alborussea, 7-9 X 3-4 
Variety c appears to be identical with Lepiota carpophylla 
B. & Br. Here, again, Berkeley and Broome noted the resem- 
blance, and stated that the latter differed from all forms of 
L. erythrogramma in the different nature of the ring. In both 
species the ring is movable ; in L. erythrogramma it is usually
