Aleurina tenuiverrucosa Dougoud & Roffler, Doc. mycol., 34 (133-134): 4 (2006).

 

Basionym Aleurina tenuiverrucosa Dougoud & Roffler, Doc. mycol., 34 (133-134): 4 (2006).

Diagnosis Receptaculum (2-) 3-6 (-10) mm diam., leviter cupulatum vel planum, tomentosum, hymenio subconcolor vel pallidius ad marginem, saturatius infra. Margo distincta, aequalis. Hymenium caelo humido a brunneo ad olivaceobrunneum, minus uvidum pallidius. Caro tenera. Hymenium 260-310 µm crassum, viriduloflavum. Asci 265-315 × 13,5-14,5 µm, opereulati, octosporati, I-, hyalini, cylindraeci, leviter inflati ad apicem rotundum, ad basim paulatim attenuati, pleurorhincho modo, aperto. Ascosporae (14,8-) 15,3-16,8 (-17,3) × (8,8-) 9,3-9,5 (-9,8) µm; X = 16,3 × 9,45 µm; Q= 1,7 (n 30 in H20), uniseriatae, ellipsoideae, polis obtusis, ornatae, intus in quibus nucleus medius in aqua adspici potest, repletae parvis in obscure cumulo guttulis ad utrumque polum; ornamentum cyanophilum, verruculis plurimis, tenuibus demissisque, interdum irregulariter densis, quae inter se cohaerere ac cristulas tenues•brevesque et parvulas insulas formare possunt. Paraphyses 3,2-4 (4,5) µm diam. inferiore parte, apice clavatae vel capitulatae, multae, basi simplici vel furcata, septatae, (0-) 1-3 (-5) septis, tantum in inferiore tertiaque parte; viridulo protoplasmate repletae. Subhymenium vix distinetum. Excipulum medullare 65- /70 µm crassum, olivaceum, textura intricata, quasi ad perpendiculum hymenii elementorum, hyphis 4-8 µm diam., cellulis 6-15 (-20) µm diam. plus minusve globulosis mixtis. Excipulum ectale 80-165 pm crassum in perihymeniali parte, 165-270 µm infra, textura angulari. Cellulae polygonales, ab isodiametricis ad ellipsoideas, quasi ad perpendiculum externae apotheciae, plerumque 20-50 (-60) × (20-) 65-100 (- 130) µm diam., pariete olivaceo; externae cellulae amorpho brunneoque pigmento indutae. Pili ad marginem 20-45 µm, infra longiores, 200-300 µm et magis etiam (× 6-9 pm diam. ad basim), paulatim tenuiores, ex externis excipuli cellulis orti, hyphoidei, plus minusve intricati, flexuosi distortique, septis (0-) 1-4, brunneoli, deinde, elongati, hyalini. Quorum pilorum jacentiumque basis paries plus minusve pigmento amorpho involutus. Ad terram nudam, argilaceo-arenosam, reperitur, ad rivorum ripas, imbuto lingo propinquo, prope Alnum sp., Salicem sp., Piceam sp., species praecipuas. Holotypus: G00068680, Suisse, Grisons, Grüsch, Prättigau, aIt. 600 m. Leg. Roffler, 05.08.2000. Paratypus: Herb. pers. RD 27.21.300.04, Suisse, Grisons, Grüsch, Sand-Au, aIt. 600 m. Leg. Dougoud, 30.09.2004.
