Cystogloea oelandica

Cystogloea oelandica P. Roberts 2006, in Roberts, Acta Mycologica, 41(1), 25 -28 (2006).

Diagnosis: Basidiomes gelatinous, hyaline, erumpent, irregularly pustular, 1 – 2 mm across, often

coalescing. Hyphae in a soft, gelatinous matrix; disarticulating and only visible as disconnected, swollen, hyphal compartments in most basidiomes examined; where vis ible, composed of branching chains of short, swollen, hyaline compartments, 10 - 35 x 6 - 17 μm, 2.5 - 3.5 μm wide at septa, lacking clamp-connexions. Hyphidia none seen. Cystidia none seen. Conidiophores none seen. Basidia arising from disarticulated hyphal segments which act as probasidia; these probasidia thin-walled, variously shaped; mostly subglobose to ellipsoid, approximate sizes 15 - 20 x 12 - 17 μm, but often fusiform, oblong to cylindrical, approximate size 25 - 40 x 8 - 10 μm, and sometimes irregular; the probasidia give rise to tubular, auricularioid epibasidia, 45 - 60 x 5 - 7 μm, which become triseptate at maturity. Sterigmata 4 - 10 (- 18) μm long. Basidiospores oblong (Q = 1.4 - 1.6), 8 - 10.5 x 5.5 - 6.5 μm, germination not seen. Figure 1.
