ENTOMOGENOUS FUNGI. 327 



Professor Thaxter's collection from Chili includes two 

 examples of Sphaerostilbe flammea Tul., from Concepcion, 

 November, 1905, and from Corral, December, 1905, respec- 

 tively. In the height of the conidial stage, these match 

 Microcera pluriseptata Cke. & Massee. The ascospores measure 

 15-22 X 6-8 {JL, and, in general, are more strongly verrucose 

 than in any other examples seen. 



When the account of the Nectrix parasitic on scale insects 

 was published, no examples of Lisea Parlatorise Zimm. had 

 been seen by the writer. This species recently occurred 

 (September-December, 1921) in fair quantity on a species of 

 Chionaspis on Gardenia florida L, in the Royal Botanic 

 Gardens, Peradeniya. The perithecia are densely clustered 

 on a thin, byssoid, purple-brown stroma, which is sometimes 

 whitish at the margin ; they are subconoid, up to 0'25 mm. 

 high, 0*3 mm. diameter, obtuse at the apex, ostiolum not 

 elevated, purple-bro^^ n becoming almost black, rough with 

 large, close-set warts composed of cells up to 16 [jl diameter. 

 The perithecial wall is thick, violet by transmitted light, of 

 large cells, with a few, stout, violet hyphae, 4 [l diameter, at 

 the base. The developing perithecia have hyphse in the form 

 of branched moniliform chains at their base. The asci are 

 cylindrico-clavate, scarcely pedicellate, eight-spored, with 

 spores obhquely uniseriate or irregularly arranged, 80 X 8 jji, ; 

 no paraphyses. The ascospores are oval or narrow-oval, 

 hyaline, one-septate, not constricted, romided at the ends, 



9-13 X 4rS^. 



The conidial stage forms white tufts at the margin of the 

 scale. These are loosely built, and consist of rather rigid, 

 branching, hyaline conidiophores, up to 0'4 mm. high, 4 ^x 

 . diameter, fasciculate below, diverging, repeatedly branched, 

 the ultimate branches solitary, often unilateral, or in whorls of 

 two or three, attenuated outwards, one-septate. The tufts 

 show a purple tinge at the base. The conidia are narrow- 

 cymbiform or fusoid, usually straight, sometimes slightly 

 curved, three-septate, 18-40 X 3-5 [i, or four- to five-septate, 

 slightly falcate at one end, 46-64 X 3-4 (jl. When old or 

 weathered, the conidiophores collapse into a confused tangle 

 which becomes purple.
