Abstract
For almost a century (42, 139) certain yeast, or yeastlike parasites of fruits and seeds have been known. They occur on a wide variety of crop plants and cause such diseases as stigmatomycosis," "yeast-spot," "eye spot," and "internal rot." They seemingly represent a phylogenetic unit. They have cylindrical or pyriform asci, and the hyaline ascospores often are characteristically arranged in two fascicles lying end to end. All have acicular ascospores. (See figs. 2, a-c; 5 , c; 11, hand i; 12, A; 13, c-h; 15,j-k.) They have similar habitats, and several species may simultaneously occur in the same fruit or seed. The majority are associated with punctures made by insects having piercing-sucking mouthparts. These fungi, along with some recently described (122, 123, 143) parasites of Crustacea, are now assembled in the family Nematosporaceae Novak and Zsolt.
