Description: Apothecia scattered, superficial, disc concave, 3 mm. diameter, drying Hay's Brown
(Ridgway), receptacle cup-shaped with a well-developed cylindrical stalk, pruinose with short,
free, hyphal tips, vertically ribbed and furrowed towards the margin, Deep Olive Buff. Flesh
homogeneous, composed of compact hyphae, 4-5 µ wide, becoming parallel at a low angle to
the surface in the outer layers. Asci clavate. long stalked, 115-120 x 10-12 µ, 8-spored, pore
not blued by Melzer's reagent; ascospores biseriate, fusoid, 10-12.5 x 3-3.5 µ; paraphyses
cylindrical, obtuse, 2 µ wide.
Notes: For this determination I am indebted to Mrs. Gamundi de Amos, who has kindly sent me part
of a collection from Nahuel Huapi National Park, which she has compared with the type in
Spegazzini's herbarium at La Plata. Massee gave the New Zealand material the apparently
unpublished name Chlorosplenium flavovirens. In spite of the presence of a greenish pigment
the structure of the apothecium seems to me that of an Helotium rather than of a
Chlorosplenium. There is already a Helotium flavovirens (Pers.) Fr.
