Descriptions
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.
