Stromata small, tubercular, 1-2 mm. in diameter, whitish to pink or flesh-colored, often 
floccose because of the erect, verticillate conidiophores; branches of the conidiophores 
ascending perpendicularly and each bearing at its summit a single conidium; conidia ellip- 
soid, hyaline, 5-8 X 34, often granular within; perithecia occurring in dense clusters rang- 
ing from 3-5 to many perithecia, the clusters very variable in form; individual perithecia 
small, nearly globose, with a prominent papilliform ostiolum, smooth or only minutely 
rough, at first flesh-colored, when dry becoming pale-yellow or almost white, 200-300 in 
diameter, entire or occasionally collapsing, becoming pezizoid; asci clavate, 50 X 5-7 4, 8- 
spored ; spores 2-seriate above, l-seriate below or often irregularly crowded, fusoid with 
ends acute, a little constricted at the septum, hyaline, 8-12 & 3-4 4. 
On bark of various kinds of trees; also on Yucca, old stump of Musa, and tree fern,

Nectria seminicola Seaver, Mycologia 1: 21. 1909. 
Conidial phase consisting of white mycelial growth covering the substratum, finally 
heaping up at various points, forming pinkish stromata; conidiophores erect, much 
branched, with branches ascending perpendicularly, each bearing at its summit a single 
ellipsoid, hyaline conidium ; conidia 5~7 2-3 4, with 1 or 2 oil-drops ; perithecia cespitose in 
dense clusters with the clusters often becoming confluent and covering the most of the ex- 
posed surface of the substratum ; individual perithecia nearly globose with a minute papil- 
liform ostiolum, smooth or nearly so, 2504 in diameter, at first flesh-colored to orange, 
fading in drying to pale-yellow or whitish; asci clavate, 40-50 long, 8-spored ; spores 
mostly 2-seriate or irregularly crowded, hyaline, 1-septate, a little constricted at the sep- 
tum, 10-14 X& 3-3.5 wu. 
On partially decayed seeds of skunk cabbage, Spathyema foetida (\,.) Raf., and also on seeds 
of cultivated beans partially decayed.
