Hypomyces Camphorati Peck, Bull. N. Y. State Mus. 105: 23. 1906. 
Stromata consisting of a thin effuse subiculum overspreading the hymenium of the host

fading ; perithecia numerous, small, immersed in the subiculum or with the necks slightly 
protruding, darker than the subiculum, pale-brownish; asci cylindric; spores 1-seriate,
