Interim Notes on Entomogenous Fungi. 



BY 



T. FETCH, B.A., B.Sc. 



TN continuation of previous communications on the fungi 

 -*- parasitic on scale insects, a paper on the species of 

 Torrubiella on those hosts has been completed, and will be 

 published as soon as circumstances permit. The following 

 undescribed species have been found among the material 

 available, much of which I owe to the continued generositj'- 

 of Professor Thaxter : — 



Torrubiella tenuis Fetch, n. sp. Stroma pulvinate, or 

 almost plane, up to 1'5 mm. diameter, white, tomentose, 

 rather loose internally, sometimes surrounded by a broad, 

 white, fibrillose margm or hypothallus. 



Ferithecia usually produced on the thicker part of the 

 stroma, sometimes on the margin or hypothallus, sometimes 

 occurring singly on scales which do not bear any stroma, 

 except a slight weft of hyphae at the base of the perithecium ; 

 scattered or clustered, elongated flask-shaped or elongated 

 conoid, 0*65-0 '9 mm. high, 0*2-0 "25 diameter below, pale 

 amber to pale yellow-brown, pale yellow or yellow-broAvn by 

 transmitted light, subtranslucent, clothed with hyphse up to 

 two-thirds their height, or almost glabrous ; asci long, 

 cylindrical, capitate, eight-spored, 7 \k diameter ; spores 

 filiform, as long as the ascus, septate, dividing into cylindrical 

 part-spores, 3-6 X 1 {ji..
