Description

Tan to olive thallus with solitary perithecia obscured by a thick thalline layer, evident only by slightly darker apical ostioles (black pits in photo are excavated/predated perithecia); MICROSCOPY: spores brown, muriform, relatively narrow, about 50-67 x 20-26 µm, with small cells in 8-10 rows & 10 cells in widest rows; ; FIELD ID: dissection required
