116. — Duportella velutina Pat. 
Specimens issued in Baker, Fungi Malayana, 25, as Dupor- 
tella velutina Pat., n. g. & n. sp., are identical with Corticium 
tristieulum B. & Br., Fungi of Ceylon, 636 = HymenocJiæte 
tristiuseula (B. & Br.) Massee, Mon. Thelephoreæ, Pt. II., 
Jour. Linn. Soc., XXVII., pp. 99-205. 
117. — Thelephora atropurpurascens B. & Br. 
Berkeley and Broome described this species from Thwaites’ 
989, as “ Effusa, hymenio granulato-rugoso atropurpureo, 
marginem versus album, breviter fimbriatum rubescente. 
Forming elongated patches about three-quarter inch wide, 
rough, with irregular raised nodules, in the centre vinous- 
brown, more red towards the white margin.” Parts of the 
type specimen are in Herb. Kew and Herb. Peradeniya. 
In Herb. Peradeniya another gathering of the same species 
is included on a sheet, which is inscribed '' 738 and 739,” i.e., 
Reticularia atrorufa B. & C. and Reticularia ve^iulosa B. & C. 
There are four pieces of bark, but they do not bear any mark 
which would enable the two species to be distinguished. 
Three of them Thelephora atropurpurascens in addition 
to a pulverulent ‘‘ Reticularia ” mass ; the fourth bears the 
former only. This gathering has been previously re-described 
in‘‘ The Mycetozoa of Ceylon,” Ann. Perad., IV., pp. 309-371. 
During the last few years Thelephora atropurpurascens has 
been gathered on several occasions, usually on dead branches 
of mango. It forms thin, effused, encrusting, more or less 
circular patches, up to 3 cm. or more in diameter and about 
0*5 mm. thick. The patch often originates from a small hole, 
such as an insect boring, in the branch, and is then umbilicate 
in the centre, and radially grooved. 
The centre is subgelatinous, the margin byssoid. The general 
colour is vinous, purplish in the centre, and reddish elsewhere. 
The margin is white. The central portion is covered with close- 
set pulvinate elevations, sometimes radially elongated. In sec- 
tion the lowest layer is red-brown and byssoid, the middle layers 
Avhite, and the upper layer brown and subgelatinous. The 
fungus is horny when dry. It is evident that this is a Punctu- 
laria^ and will stand as Punctularia atropurpurascens (B. & Br.).
