Characteristics

Ascomata globose to subglobose, with a long, wide, brown, septate stalk or sessile and attached to substrate by wide (usually >10 μm), brown septate hyphae, immersed, partly immersed, or superficial, ostiolate, papillate, coriaceous to subcarbonaceous, hyaline, pale brown or black. Peridium thick, comprised of a few layers of relatively large cells. Hamathecium pseudoparaphysate, hyphal-like, filamentous, septate, unbranched between the asci, branching and anastomosing above the asci or septate, branched and persistent, separating to form cavities as asci separate from ascogenous hyphae to move upwards. Asci ovoid, cymbiform, saccate, clavate or cylindrical, thick-walled, bitunicate, fissitunicate, persistent or deliquescent. Ascospores ellipsoid–fusiform, 1-septate, becoming 3- or 4- septate at germination, apical cell slightly larger or equal in size to the basal cell, slightly or strongly constricted at the midseptum, smooth or rough-walled, with or without a gelatinous sheath, gelatinous pads, apical cellular appendages or elongated gelatinous apical appendages. Hyphae in culture wide (usually >10 μm), brown, septate unconstricted to strongly constricted at the septa. Included family: Aliquandostipitaceae Inderb.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
