Bovistella citrina (B. & Br.) Lloyd. Described by Berkeley 

 and Broome in Fungi of Ceylon, No. 724, as Lycoperdon 

 citrinum, from Thwaites 738 cum icone. Recently collected 

 No. 2414, Peradeniya, June, 1907 ; No. 2515, Peradeniya, 

 October, 1907 ; No. 2645, Hakgala, September, 1908. 



Up to 4 cm. diameter, globose, or depressed globose, 

 sometimes lacunose below, lemon-yellow, pale towards the 

 base, with a delicate cortex of minute white spines ; usually 

 arising from stout cord-like myceUum. Old specimens 

 dark red-brown when moist, drying to dark shining olive, 

 covered with minute, deep red-brown, or almost black, 

 warts. No sterile base. Mass of spores and capillitium 

 olive. Capillitium threads yellow-brown, stout, thick- 

 walled, 3-10 [K diameter, branching usually at a wide angle, 

 with occasional septa above the forks. Spores globose, 

 3-4 [L diameter, pale olive, very minutely echinulate, with 

 hyaline pedicels up to 16 [). long. 



When growing, this species appears entirely lemon- yellow, 

 but a close examination reveals a very dehcate cortex of 

 minute white spines or warts. On some specimens this 

 cortex may disappear at maturity ; in others it persists and 

 dries in the form of minute warts. The yellow wall is 0*5 

 mm. thick on the immature specimens, but it becomes thin 

 and papery when mature. 



Bovistella conspurcata (B. & Br.). Described as Lycoperdon 

 - cons'purcatum by Berkeley and Broome in Fungi of Ceylon, 

 No. 723, from Thwaites 193 bis. The type in Herb. Kew 

 is marked by Thwaites, " mixed with 193, I believe, in a 

 previous gathering." There are only two specimens. 

 No. 193 was L. j^urpurascens ; there is no mixture in the 

 specimens of 193 in Herb. Peradeniya. 



Berkeley and Broome's description is " globose, peridium 

 minutely verrucose, here and there cracked, base small, 

 shortly rooting ; capillitium and spores olivaceous ; spores 

 pedicellate, 3*75 ^jl diameter, 12*5 ^x long (including the 

 pedicel). Scarcely an inch across. Externally resembhng 

 L. australe, but with differently coloured spores, wliich are 

 stipitate,"
