Basionym Karstenella vernalis Harmaja, Karstenia, 9: 20 (1969).
Diagnosis Ascocarpus tenuissimus, omnino stricte ad substratum appressus, surrotundus, 3-12 mm in diam., pro maxima parte fuscoruber, ad marginem pallidior, aurantiacus-chlorinus. Probabiliter gymnocarpus. Sporae 12,0-15,0 × 5,5-7,2 µm, uniseriatae, ellipsoideae, equilaterales, satis tenuitunicatae (tunica ca. 0,4 µm), laeves, perispora non observatur, in KOH hyalinae, in solutione Melzeri subflavidae, in «Cotton Blue» in acido lactico cyanophiloidae, sporae intus eguttulatae, homogeneae. Asci 150-190 × 8,0-12,5 µm (longitudo tota), cylindracei, octospori, apice leniter attenuato et curvato quando maturi, in KOH ± hyalini, in solutione Melzeri flavidi, tunica omnino satis tenui (ca. 0,5 µm), ascostomate leniter obliquo. Paraphyses valde tenuitunicati, recti, simplices, filiformes, apice saepe leniter incrassati (3,0-6,0 µm), haud incrustati, parce septati, plasmate in KOH sordide pallide viridi, in solutione Melzeri sordide flavido. Excipulum e hyphis filiformibus, 3,0-5,0 µm crassis, septatis, defibulatis, tenuitunicatis, laevibus, in KOH hyalinis- subflavidis, in solutione Melzeri subflavidis. Pars exterior excipuli e textura intricata typica; in parte interiore hyphae minus intricatae, multae earum horizontales. Subiculum (?) e hyphis filiformibus intricatis subter ascocarpo in substrato sitis constat, quae simul marginem angustum albidum ascocarpi formant. Hyphae subiculi 3,5-7,5 µm crassae, rectangulare ramosae, septatae, defibulatae, satis crassitunicatae, dense papillatae, in KOH flavidae-brunneolae, in solutione Melzeri pallide fuscae, valde cyanophiloidae in «Cotton Blue» in acido lactico.
Ad terram et ad ramulos putrescentes Coryli avellanae et in detrito alio, plerumque Coryli. Vernalis.
