lent me by Dr Spegazzini. This is on an Aspidiotus on Dry mis 

 Winteri, collected at Bahia de Corral, Chili. The fungus forms 

 a more or less pulvinate, lemon yellow stroma over the scale, 

 with a thin spreading margin, composed of thick-walled, yellow 

 or hyaline, irregular hyphae, often closely verrucose. There is 

 no doubt that these are the stromata of a Torrubiella, and in 

 one example a developing perithecium was present. They 

 appear to be undoubtedly the stromata of T. bar da. Numerous 

 conidia, hyaline or yellowish, verrucose, oval, 4-5 x 3/Lt, or 

 globose, 3-4 /x diameter, were seen, usually singly, sometimes 

 in chains, but these all arose from thin-walled, hyaline hyphae, 

 1-5 /x diameter, which did not appear to be connected with the 

 hyphae of the stroma. Spegazzini described the conidia as 

 ellipsoid, 7-8 x 6/>t; it is probable that he saw other conidia 

 which are those of the conidial stage of Torrubiella bar da.

 "Felipe Poey," iii (1918), p. 80. 



Perithecia vivid yellow, erect, conical, scattered or confluent, 

 350 /M high, 125 /u. diameter. Asci linear, 175-245 /x long. Asco- 

 spores dividing into cylindrical part-spores with rounded ends, 

 3-32 X 1-66 /x.

The above is Johnston's description. I have not seen a 

 specimen. Mr Johnston, in litt., states that the perithecia were 

 yellow, with rather translucent yellow ostiola, and necks some- 

 what tapering or rounded at the apex; isolated perithecia were 

 yeUow-tomentose, but when several grew close together they 

 were invested by yellow mycelium. On the characters of the 

 apex of the perithecium, T. Lecanii would appear to be quite 

 distinct from T. bar da. 



To afford a comparison with the species of Torrubiella which 

 are parasitic on other insects, the following account of the other 

 known Ceylon species is included. One of these, which occurs 

 on an undetermined Noctuid, appears to be T. ochracea Pat. 

 The other, which is apparently a new species, occurs on spiders ; 

 it is described below as Torrubiella flava. 



Torrubiella ochracea Pat. In two examples of this species, 

 collected on different occasions on the perfect insect, a rather 

 loose pale yellow weft of hyphae extends along the body and 

 the legs of the insect and binds them to the leaf. This mycelium 

 does not cover the wings, but it fastens the wings to the body, 

 and comes just up to, or slightly over their margins. When old 

 the colour of the mycelium fades to almost white. The perithecia 

 occur anywhere on the mycelium, but more particularly along 

 the margins of the wings and along the legs; they may be scat-
