Hypocrella tubulata Fetch, n. sp. — Perithecial stromata 

 white, minutely tomentose, varying from pulvinate, 1'6 mm. 

 diameter, 1 mm. high, slightly tuberculate, or strongly tuber- 

 culate with rounded tubercles, 0'4 mm. diameter, to flattened 

 pulvinate, 2 mm. diameter, '6 mm. high, strongly tuberculate 

 and irregularly divided ; usually with a fibrillose or scarious 

 hypothallus which may be 1 mm. wide in the flatter irregular 

 forms ; ostiola slightly elevated, yellow, translucent ; perithe- 

 cia from subglobose, 0'4 mm. diameter, to narrow flask- 

 shaped, 0'2-0-4 mm. diameter, 0*4-0 '7 mm. high, embedded 

 singly in the tubercles in the flatter forms, and in the stroma 

 in the pulvinate forms, in the latter case opening through the 

 tubercles if present ; asci up to 200 x 8-10 \}. ; part-spores 

 cylindric with rounded ends, or narrow-oval, 7-12 x 2-2*5 |jl. 

 Aschersonia stromata sometimes pulvinate and even, usually 

 a pulvinate or flattened disc up to 2 mm. diameter, from which 

 arise columnar processes, either abruptly or gradually ; 

 processes conical or cyhndric, up to 0*6 mm. high, 0*4 mm. 

 diameter, truncate at the apex, with a wide ostiolum which 

 is often laterally compressed ; stroma white, minutely tomen- 

 tose, with a tomentose or fimbriate margin, becoming more 

 compact and subglabrous when old ; tissue of the columns 

 composed of more or less parallel hyphse ; pycnidia cylindric, 

 globose, or lenticular, sometimes convoluted at the base, 

 usually with a long cylindrical neck ; pycnospores fusoid, 

 ends blunt, 8-10 x 1'5 ^J^; paraphyses linear, up to 150 \). 

 long. 



Tliis species was collected by Parkin, in the Aschersonia stage, 

 on an Aleyrodes on Eugenia revoluta, Horton Plains, Ceylon, and 

 was described by him on page 39 of his paper {Aschersonia C). 

 He stated: "The mature stroma })Osses3ed a hypothallus sur-
