It would seem, on examination, that the colour is dissolved out 
of the hyphae, ? by rain, and tinges the cuticular layer just as 
“Soudan red”’ will do. 
The description of the Leptosphaeria is as follows :— 
LEPTOSPHAERIA PHORMII, sp. nov. 
Perithecia circa 400» diam., lentiformia, atra, opaca, tecta, 
dein vertice erumpentia, basi hyphis purpurascentibus obsita ; 
contextu crasso, parenchymatico, subpurpureo-brunneo.  Asci 
elliptico-oblongi, apice rotundati, tenuissime tunicati, breviter 
pedicellati, 8-spori, paraphysibus parcis vel nullis cincti; sporidia 
biseriata, elliptica, 3-septata, ad septa subconstricta, 18-20 x 7- 
7:5 pw, loculis dilute fuscidulis. 
In foliis emortuis Phormit, in Scotia (Boyd). 
992. Phoma pelliculosa, B. & Br. 
This a curious species, belonging to the section 
Pycnothyrieae of the Leptostromaceae, and if a slight emendation 
be made it can be placed in Spegazzini’s genus Hriothyrium 
(Sacc. Syll. x. 418). The only other known species of Hriothyrium 
(Z. dubiosum, Speg. l.c.) differs in its fuliginous subiculum and 
its more ovoid spores. Whether the two are really congeneric or 
not, cannot be decided until more allied species are found. 
ERIOTHYRIUM, Speg. emend. 
Pyecnidia minute, scutato-dimidiate, adnate, ostiolate, sur- 
rounded by an effused very thin smoky or fuscous-pallid 
subiculum. Spores hyaline, continuous, oblong or ovoid. 
ERIOTHYRIUM PELLICULOSUM, Grove. 
Pycnidia black, 50-100 diam., crowded, round, shield- 
shaped, dimidiate, applanato-convex, pierced by a wide central 
round or irregular impressed pore; texture of dark-brown cells, 
about 2-3 w diam., distinctly radiating, especially at the margin. 
Spores narrow-oblong, straight or curvulous, about 3 x lp; 
sporophores rod-shaped, up to three times as long, springing from | 
the underside of the shield. (Fig. 6c.) 
Under the cuticle of Bamboo stems, Peradeniya (B. & Br. 
Ceylon Fungi, no. 438 !). 
The pycnidia have a similar texture to that of Actinothecium 
caricicolum, Ces. (Sacc. Syll. iti. 639). They consist of a thickish 
shield-shaped brown layer, lying on the destroyed epidermis, and 
formed of linear or ellipsoid cells distinctly radiating round the 
margin; this margin is, when untouched, continuous as in the 
simpler specimens of the Actinothecium, or as in Actinothyrium, 
1.e., except for single projecting cells, it is not deeply indented, 
yet on the slightest pressure the shield splits into radiating 
sectors, though none of them were ever so deeply partite as the 
extreme forms in Cesati’s figures in Hedwigia, i. 80, pl. 11, f. 3.
