4. Nectria zonata Seaver, Mycologia 2: 180. 1910. 
Perithecia preceded by a scant mycelial growth, which starts from a given point and 
radiates equally in all directions, forming concentric rings or zones but never giving rise to 
a stroma; rings or zones 2-10 cm. in diameter, spreading over the substratum, the white 
color disappearing in the central portion and soon followed by the widely scattered peri- 
thecia, which are inclosed within the outer rings of the advancing mycelium ; perithecia 
pale-orange, ovoid, smooth or nearly so; asci clavate, 8-spored ; spores partially 2-seriate, 
fusoid, slightly unequal-sided, smaller toward the lower end, 1-septate, slightly constricted 
at the septum, filled with oil-drops, 18-20 8-104. 
On the outside of pots containing plants in greenhouses; also occurring more rarely on the 
surface of soil in the presence of algae.
