Pyronemataceae
The Pyronemataceae are a family of fungi in the order Pezizales. It is the largest family of the Pezizales, encompassing 75 genera and approximately 500 species. Phylogenetic analyses does not support the prior classifications of this family, and suggest that the family is not monophyletic as it is currently circumscribed. Morphology Members of the family are diverse in ascomatal or cleistothecial form. Individual taxa may be sessile (without a stipe) to shortly stipitate, cupulate (cup-shaped), discoid (disc-shaped), pulvinate (cushion-shaped), or with turbinate (turban-shaped) epigeous apothecia. Also, taxa may be sub- hypogeous to hypogeous with closed, folded, or solid ascomata. Apothecia may range in size from less than 1 mm up to in diameter, and may be brightly colored due to carotenoid pigments. Genera Genus (; : genera ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as vir ...

Chaetothiersia
''Chaetothiersia'' is a fungal genus in the family Pyronemataceae. It is monotypic, containing the single species ''Chaetothiersia vernalis'' collected from California. Description This species is characterized by having stiff brown hairs on the surface of the ectal excipulum, the outer layer of the apothecium. The ectal excipulum is thin, and made of roughly spherical to somewhat spherical/angular cells. Its ascospores are smooth, and do not contain oil droplets. Lookalikes Genera with species that bear a resemblance to ''C. vernalis'' include ''Geopora'', ''Humaria'', ''Trichophaea'', ''Trichophaeopsis'', ''Tricharina'', most of which are distinguishable only by examining microscopic characteristics. Etymology The etymology of the generic name is derived from the Greek language, Greek ''chaeto'', meaning hairy (a reference to both the external hairs on the cups and to Dr. Thiers' first name), and "thiersia", in honor of mycologist Harry Delbert Thiers, Harry Thiers, one ...
