Mycocalicium hyaloparvicellulum Daranagama & K.D. Hyde

in Ariyawansa & al., Fungal Divers.: 102, 2015.
Distribution: S - Cal (Ariyawansa & al. 2015).
Description: Thallus not evident, not lichenized. Apothecia stalked, pin-like, 1-1.5 mm high. Stalk brown to pale brown, consisting of light brown, periclinally arranged hyphae, with a gelatinous coat. Capitulum lenticular to subglobose, shiny black, often with a granular surface. Excipulum 15–26 μm wide, pale brown; mazaedium absent; hypothecium dark brown to olivaceous brown, 80–95 μm high. Asci cylindrical, 56-83 µm long, formed singly, with a single functional layer, strongly and uniformly thickened at apex, without a canal, with uniseriately arranged ascospores, persisting until the spores are mature. Ascospores 1-celled, pale brown, ellipsoid, with a pointed and a rounded end, 10-15 x 4-6 µm, smooth-walled. Pycnidia black, with a distinct apical pore. Conidia pale brown, globose, 5.2–7.5 μm in diam., arranged in chains. Photobiont absent. Spot tests: ascocarps K-, C-, KC-, P-. Chemistry: without lichen substances.
Note: a recently-described species, closely related to M. subtile, but differing in apothecium size, colour and structure of stalk, ascus size and spore dimensions and colour. The type material was growing as a saprobe on cones of Pinus halepensis in the Mediterranean belt.
