Hyaloscypha herbarum on a cone of Pinus sylvestris
B Shelbourne, 18-11-2024 00:06
B Shelbourne• Macro and habitat seem hyaloscyphoid.
• Hairs and spores suggest Hyaloschypha (s.s.).
• Simple septa, rings, hairs, spores and substrate seem to suggest H. herbarum.

Habitat: On a decaying cone of Pinus sylvestris, mostly on the more sheltered inner parts, damp when found, on the floor with litter, under several large trees, on a sparsely wooded hillside, 197 m alt., Old Lodge nature reserve, Ashdown Forest, High Weald, southern England, early-November.

Apothecia: Tiny whitish discs, gregarious to 2-caespitose, sessile.

Macro: Diameter < ~0.5 mm, whitish-translucent, occasionally yellowish, initially more cupulate, then discoid-pulvinate and +/- appressed, margin more whitish, becoming flattened and often slightly uneven, with dense and short whitish hairs pointing outwards and some longer ones, disc distinctly convex in maturity, more translucent with the dark substrate showing in the centre, grainy appearance (hymenial cells).

Asci: Turgid ~(45) 50-60 x 7-8 um, simple septa, rings bb.

Spores: Cylindrical-allantoid to slightly clavate, usually approx. homopolar, ends rounded, tapering slightly, usually ~3-5 small LBs grouped at each pole, OCI 2-3, asymmetric or sometimes slightly to distinctly curved.

Free living spores in water:
(9.4) 10.3-13.1 (14.7) × (2.2) 2.6-3.0 (3.2) µm, Q = (3.5) 3.7 - 4.9 (5.3), N = 35, mean = 11.9 × 2.8 µm, Q mean = 4.2.

Paraphyses: Cylindrical, apex not noticeably inflated, width ~2-2.5 um.

Medullary: Some horizontal hyphae seen, otherwise ?

Ectal: Text. prismatica, at the base more round, slightly larger cells at the flanks and often branching before becoming hair-like, general dextrinoid reaction.

Marginal hairs: A few long and cylindrical, length ~70-100 x 2-3 um, apex rounded, otherwise short and tapering, ~25-40 x 5 um, at the apex ~1 um wide, conical to distinctly lageniform, with an apical inflation, blunt/obtuse, appearing smooth, possibly a slight amyloid reaction at apices.
