Pezizaceae
Conservation status. Endangered [EN B2ab(ii,iv)].
Morphology and biology. Fruit-bodies (apothecia) sessile, 0.5–1.8 cm in diameter, at first shallow cup-shaped with even margin, later expanded to almost flat with smooth hymenium and smooth outer surface, unicolorous black brown. Spores ellipsoid, 15–22.5 × 7.5–12.5 µm, unicellular, with small, uniform disposed spines on the coat surface and with one bigger and several smaller oil drops, hyaline. VII–X.
Habitats and populations. On soil in damp places in deciduous and mixed woods.
Distribution in Bulgaria. Vitosha Region (Vitosha Mt – under the Bor chalet and along the way Chuipetlovo – Kladnitsa villages).
General distribution. Europe, Asia, North America.
Threats. Habitat changes as result of wood plantation, wood extraction, tourism development, atmospheric pollution; change in native species dynamics (directly impacting habitat).
Conservation measures taken. Included in the Red List of Fungi in Bulgaria. The localities are situated on the territory of the Vitosha Nature Park and in a site of the European ecological network Natura 2000 in Bulgaria.
Conservation measures needed. Research into the species biology and ecology; inclusion in the National biodiversity monitoring system; research into the distribution and populations state; preservation of the localities of the species.
