Hypocreopsis lichenoides  

Anamorph: conidial production sometimes visible as a powdery surface of the stroma, forming a closely packed palisade of percurrently proliferating conidiogenous cells 26-38 x 6.5-7.5 µm in size. Conidia 9-11 µm diam., spherical, thick-walled, yellowish, aseptate, minutely asperulate, without a gelatinous sheath or appendages [some information from Cooke, 1952]. Previously known as Stromatocrea cerebriformis.
Teleomorph: stromata 15-35 (-110) mm diam. and 2-4 (-5) mm thick [fide Stasinska, 2004], irregularly radially ridged with branched finger-like projections to the periphery, orange-brown to pale brown or ochraceous, sometimes reddish, the outer parts often less strongly pigmented, initially smooth but becoming rugose in the central part and often with a farinose appearance due to production of conidia. Ascomata perithecia, immersed in stromatic tissue with the ostioles visible as brown dots over almost the entire stroma surface, ± globose, the neck papillate and hardly extending beyond the surface. Interascal tissue absent at least at maturity, though probably with apical paraphyses. Asci cylindrical, thin-walled, not fissitunicate, with a minute apical ring that does not blue in iodine, 6- to 8-spored. Ascospores arranged uniseriately, (16-) 18.5-23 x 7.5-10 µm, rather variable in form but mostly broadly fusiform to fusiform-ellipsoidal, the ends usually distinctly pointed, rather thick-walled, with a median septum, hyaline, minutely verrucose (ornamentation only visible easily using an oil immersion lens), without a gelatinous sheath or appendages, not aggregated in clusters when ejected.
