PEZIZALES: epigeous ascocarps with operculate ascus; families: Ascobolaceae, Helvellaceae, Humariaceae, Morchellaceae, Otideaceae, Pezizaceae, Sarcoscyphaceae, Tuberaceae( in its own order, Tuberales).

hypogeous ascoma;
in middle frame, the asci form a hymenium (tan)
lining the insides of the invaginated folds
Genabea Geopora cooperi Tuber

Elaphomyces: ascocarps hypogeous; ascus spherical, inamyloid,without an operculum, and with no trace of a spore discharge mechanism;ascus prototunicate; ascospores globose, 2 to 3 per ascus; hymenium absent. This is probably the most abundant hypogeous ascomycete in Big Lagoon Spruce Forest. In what order would you place it. What is the ploidy number of the ascospores in Elaphomycesand in Tuber? What changes must occur in the life cycle of these fungi for this ploidy number to take place?
