purple, rather dull. Capillitium originating from the apex of 

 the short colurnella, threads blackish-purple, very slender, equal 

 throughout, repeatedly forking from the base, angles very acute. 

 Stem coloured like the sporangium and twice as long, slender 

 above, becoming very thick downwards, and expanding into a 

 small circular hypothallus. Spores in clusters of five to seven, 

 globose when free, pale lilac, minutely warted, 15 to 16 /x diam. 

 About 1 mm. high. Mass., Mon., p. 98. Badhainia penetralis

Nothing now remains in the Kew Herb. (K. 614) of the specimens 

 first issued by Ellis under the name of B. penetralis but a few subulate 

 stalks. The specimens issued as Comatricha Ellmana syn. Lamproderma 

 Ellisiana Cke., Badhamia penetralis Cke. & Ellis, 2nd series, No. 2696 

 (K. 1590), are Comatricha laxa. 



12. L. Lycopodii Raunk,, in Bot.Tidssk.,xvii., p. 109. Sporangia 

 scattered, globose, sessile on a violet-brown hypothallus ; wall, 

 columella, capillitium, and spores violet-brown ; the lower part of 

 the wall remains with tattered margin. Columella cylindrical, 

 reaching nearly half the height of the sporangium, giving rise in 

 the upper part only to the capillitium, whose threads fork more 

 and more towards the surface of the sporangium, where they are 

 combined into a net by transverse branches, the extremities 

 almost colourless. Spores furnished with a delicate network of fine 

 thickenings, 12 to 18 ^ diam. Stemonitis cribrarioides Fr., Syst.
