Chalara distans McKenzie 1993

Colonies inconspicuous, effused, brown, with white layer of conidia. Mycelium superficial, brown, branched, smooth, septate, 1.5-2.5 µm thick. Conidiophores macronematous, mononematous, single, unbranched, erect, straight or slightly curved, smooth, 1-3 septate, pale brown, 60-100 µm long (including conidiogenous cell). Conidiogenous cells monophialidic, integrated, terminal, lageniform, (37-) 60-80 µm long; venter subcylindrical, (12-) 20-30 (-34) x 6-10 µm; collarette cylindrical, (25-) 35-50 (-55) x (2.75-) 3-4 (-4.5) µm; transition from venter to collarette gradual or occasionally abrupt; ratio of mean lengths of collarette and venter = 1.7:1. Conidia endogenous, extruded in long chains, hyaline, cylindrical, smooth or slightly verruculose, medianly 1-septate, (17-) 18-22 (-23) x (2.5-) 3 (-3.5) µm, apex rounded, base truncate; mean conidium length/width ratio = 6.3:1.
On Dracophyllum arboreum Ckn.
Coloniae inconspicuae, effusae. Mycelium extermum, ex hyphis brunneis, ramosis, laevibus, septatis, 1.5-2.5 µm crassis. Conidiophora macronematosa, mononematoua, singula, eramosa, erecta, recta vel parum curvata, laevia, 1-3 septata, pallide-brunnea, 60-100 µm longa. Cellulae conidiogenae monophialidicae, in conidiophoris incorporatae, terminales, lageniformes, (37-) 60-80 µm longae; venter subcylindricus (12-) 20-30 (-34) x 6-10 µm; collum cylindricum, (25-) 35-50 (-55) x (2.75-) 3-4 (-4.5) µm; transitio e ventre ad collum gradata vel interdum abrupta; ratio longitudinis mediae colli et ventris =1.7:1. Conidia endogena, catenulate extrusa, hyalina, cylindrica, laevia vel minute verruculosa, l-septata, (17-) 18-22 (-23) x (2.5-) 3 (-3.5) µm, apice rotundato, basi truncata; ratio conidii long/lat. = 6.3:1. In fohis dejectis epacridaceae speciei Dracophylli arborei Ckn. Holotypus PDD 49389.
The specific epithet refers to the geographical remoteness of the type locality.
In its morphology Chalara distans clearly differs from described species of Chalara.
Specimen examined: New Zealand, Chatham Islands, Rekohu, Taiko Camp, 8.III.1983, E. H. C. McKenzie (PDD 49389 - holotype).
