332 FUNGUS-FLOEA. 



showing a tendency to become polygonal, 5-6 fj. wide Ly 

 15-25 [jt. long, radiating from stem to margin; externally 

 pilose, the hairs longest at the margin, where they form a 

 fringe; 60-100 X 4-6 /jl, cylindrical, obtuse or very slightly 

 thickened at the apex, which is crowned by a regular 

 octahedron-crystal of oxalate of lime, usually rough with 

 ■very minute particles of lime throughout their length, thin- 

 walled, distinctly septate ; asci cylindric-clavate, thick at 

 the base, 8-spored ; spores cylindrical or narrowly fusiform, 

 straight, hyaline, continuous, 6-8 X 1 ^ ; paraphyses lanceo- 

 late, tip acute, about half as long again as the asci, hyaline, 

 4 ft, thick at the widest part.

Authentic specimen from Phillips examined. 



Closely allied to D. virginea, differing in the slightly longer 

 stem, larger cells of the excipulum, and more especially bj' 

 the rough, thin-walled, distinctly septate hairs, each of which 

 is tipped with a perfectly symmetrical, regular octahedral 

 crystal of lime, the angles of which frequently present the 

 appearance of a cross under the microscope. The crystals 

 often drop off when the plant is placed in water for exa- 

 mination. D. echinata, Awd., differs from the present in the 

 shorter, stouter, thick-walled hairs being tipped with a large 

 agcregHtion of crj'Stals having numeious projecting sharp 

 points.

Scattered or crowded, very shortly stipitate, at first 

 depresso-globose and closed, then expanded but not becoming 

 plane, f-1^ mm. across ; disc varying in colour from yellow 

 to deep orange, externally white, densely pilose, hairs 

 .-■lender, cylindrical, septate, obtuse, hyaline, minutely rough, 

 sometimes inclined to be rather wavy, 150-260 x 4-5 //,; 

 cortex parenchymatous, cells hexagonal, elongated in the 

 direction from base to margin, running in more or less 

 parallel series, 9-^14 x 5-7 /a; asci small, cjlindric-clavate,
