Description

Systemic in shoots, causing hypertrophy in infected leaves and shoots; hymenium hypophyllous, white, basidia at first protruding between epidermal cells in fascicles of 3-6, forming a continuous layer over undersurface of leaf at maturity, subclavate, projecting 25-35 µ, beyond cuticle, 4.0-5.0 µ. wide; sterigmata 2, conical, 2.5-3.5 µ. long; basidiospores hyaline, smooth, cylindrical, slightly hooked at base, 13.0-19.0 x 2.5-3.5 µ, average 15.5 x 3.0 µ, germinating spores 0-(4)-septate; conidia absent.

Distribution

New Zealand.

Latin

Systemicum in surculis, efficiens hypertrophiam in frondibus et stirpibus infectis, hymenio albo, plerumque hypophyllio; basidia subclavata, 3-6-nario disposita, 25-35/i ultra cuticulam eminentia, 4.0-5.Ofi lata; sterigmata 2, conica, 2.5-3.5/i longa; basidiosporae hyalinae, leves, cylindricae, tenuiter hamatae ad basim, 13.0-19.0 (15.5) x 2.5-3.5 (3.0)/i sporae germinantes 0-(4)?septatae; conidia absentia.

Notes

The host is an indigenous species occurring in the mountains of both islands and extending to Australia and Tasmania (Allan 1961, p. 514). Infection by Exobasidium pentachondrae causes shoots to become hypertrophied, elongated, and red-violet in colour.

E. pentachondrae is characterised by narrow, bisterigmate basidia and narrow cylindrical spores.
