CEYLON FUNGI. 
161 
In very wet weather this fungus assumes quite a different 
form. Instead of coalescing into a flat stroma, the hyphæ 
remain more or less free, and form loose, pulvinate, floccose 
tufts up to 6 mm. thick, 2 to 3 cm. long, and I to 2 cm. 
broad. These are at first lavender with a white margin, then 
lavender to grayish-blue in the centre, and reddish-purple 
outwards ; they finally collapse into a purple-brown mass 
of matted hyphæ and spores. The hyphæ are lax, about 
3 ^ diameter, often agglutinated into strands, purple-brown 
when old. The ultimate sporiferous branches are simple and 
1*5-2 [L diameter. The conidia are purple-brown, spherical, 
4 ^ diameter, or oval, 5-6 X 3-4 minutely verrucose ; they 
are at first terminal, becoming lateral through the further 
growth of the hyphæ. 
This second form may be found on the same branches as 
the Punctularia, and in some cases a Punctularia stroma may 
give rise to this growth, either on one side, or all round the 
margin. The inclusion of Punctularia atropurpurascens with 
“ Reticularia atrorufa ” and Reticularia venulosa ” on the 
herbarium sheet is thus explained. I may add that the fungus 
grows in my garden at Peradeniya and I have had numerous 
opportunities of observing it. 
Reticularia atrorufa B. & C. and R. venulosa B. & C. were 
originally described by Berkeley from Cuba. Massee (Jour. 
Myc., 1889, p. 185) referred both to Trichosporium Curtisii. 
Torrend has found (Bull. Soc. Portugaise des Sciences Nat., 
IV., fasc. 1, p. 9) that Reticularia venulosa B. & C.- is a 
Ceriomyces form of Punctularia tuberculosa Pat. 
The Ceylon Punctularia atropurpurascens (B. & Br.) would 
appear to be different from Punctularia tuberculosa Pat. It 
agrees with the latter in having a Ceriomyces form, which has 
been attributed to the Cuban species Reticularia atrorufa and 
R. venulosa. 
118. — Cyphella epileucina Sacc. 
This species was described by Berkeley and Broome as 
Cyphella epileuca B. & Br. Alutacea, pruinosa, pileo 
galeato e mycelio tenui albo oriundo ; hymenio lævi, sporis 
binucleatis.” The name was changed by Saccardo, because of 
the existence of a previous Cyphella epileuca B. & C. It
