Helotium brevisporium Cooke & W. Phillips 1879

Latin

Ochraceum,.sessile, sparsum (1-3 mm.). Cupulis applanatis, concavis ; margine pallido, elevato. Ascis cylindricis. Sporidiis breviter ellipticis, demum uniseptatis (.007-.0l x .003-.004 mm.) Paraphysibus linearibus.

Notes

Described with some hesitation as the specimen was small. It is therefore subject to future confirmation.

Typification

On decorticated sticks. Waitaki (30 b).

Helotium brevisporium Cooke & W. Phillips 1879

Description

Helotium brevisporum Cooke & Phillips in Grevillea 8, 63 (Dec. 1879).

Apothecia scattered, superficial, subsessile; disc flat, up to 3 mm. across, ochraceous, with a low obtuse margin; receptacle saucer-shaped, paler than the disc, smooth, with a short stout stalk, largely immersed in the substrate. Excipulum of parallel hyphae lying at a moderate angle to the surface, 4-5 µ wide, with rather thick hyaline walls; flesh of loosely woven hyaline hyphae, stained brown in the base of the stalk only. Asci cylindric-clavate, about 75 x 6 µ, 8-spored, pore blued by Melzer's reagent; ascospores uniseriate, elliptical, 8-12 x 3-4 µ, becoming 1-septate. Paraphyses cylindrical, 2 µ wide. On decorticated wood.

Notes

[Notes from Kew Type specimen, PRJ 2010] In K, filed as Bisporella Dennis' description recalls a sessile Crocicreas, clearly illustrating excipular elements arranged more or less in parallel. Type looks like it might have been substipitate. A second specimen cited by Dennis, Sinclair No. 8. is not in great condition In (macroscopically appears mouldy) but clearly stipitate and looks macroscopically just like B. citrina. Squash mount shows excip to be Crocicreas, parallel rows of hyphae in gel matrix - what appear to be mould on outside of disc are in fact a layer of crystals.
