Dear friends. Basidiomata fully resupinate growing on the bark of Alnus lusitanica covering several cm; with a membranaceous, non-waxy, porulose consistency, arachnoid when dry, light grey, whitish-grey, with diffuse, not well delimited margins, without rhizomorphs. Clamped hyphae from the subiculum difficult to distinguish, which form a very narrow layer under the hymenium, and do not appear to have ampullate dilatations at the septa or any particular content. Hyphal system monomitic. Basidia clavate < 20 µm long, 4-spored, most likely pleural. Basidiospores hyaline, subespherical or very broadly ellipsoidal, finely spinulose. No cystidia. I'm not sure what genus fits well with this collection, perhaps a Trechispora? I would appreciate any help.

Maybe Phlebiella (Xenasmatella)? |

HI! Have you checked if the spores are positive to Melzer's reagent? |

Hi Aphyllo The spores are not amyloid (Mlz.(-) in my pic. Finally, taking into account the microscopic and especially the macroscopic characters, such as the existence of a hymenium that is not continuous, neither waxy nor gelatinous, but discontinuous and porulose, I think that Xenasmatella (Phlebiella) fibrillosa could fits well with this collection. Thank you
