Colonia dissita vel gregaria et confluentia, ambitu irregulari et crassitudine variabili, velut pallidas vel luteolas, lucentes, gelatinosas crustas perceptibiles. Mycelium immersum et superficiale ex hyphis irregulatim ramosis, remote septatis, parietibus incrassatis, hyalinis, 1.5-2.5 µm lat., compositum. Conidiomata sporodochioidea, stromate basali tenui, constato e cellulis isodiametris ad angularibus, hyalinis. Conidiophora e cellulis summo strato stromatis basalis enascentia, simplicia vel irregulatim ramosa, septata, hyalina, laevia. Cellulae conidiogenae discretae, clavatae ad subcylindraceae, rectae vel leniter curvae, hyalinae, laeviae, 5-12(-15) (mean = 8.8) x 1.5-3 (mean = 2.2) µm. Hyphae steriles ramuli conidiophorarum exorientes, filamentosae, aseptatae vel aliquando parce septatae, hyalinae, laeviae, usque ad 150 µm long et 1.5-2.5 µm lat., pro parte majore in mucum manifeste ad extremum distale vestitae. Conidia holoblastico-singula, ad apicem cellulae conidiogenae exorientes, naviculata, cum apice lato et obtuso, et base uno podetio decrescenti praedita, unicellularia, hyalina, laevia, 17-35 (mean = 26) x 3-3.5(-4) (mean = 3.3) µm, apicaes et persaepe basales appendices ferentia. Appendix apicalis infundibuliformis, mucosis, caule tereti (2-3 x 1-1.5 µm), cono 3-5.5 x 4-6 µm; appendix basalis, ubi adest, teres, mucosis, 1-5 x 1-1.5 µm. HOLOTYPUS: PDD 33689.
A viable culture of the fungus obtained from P. sitchensis is available in the Mycological Herbarium of the University of British Columbia as isolate No. 6597 and has also been deposited in the National Culture Collection, Ottawa (DAOM).
Colonies scattered, glistening, gelatinous crusts, irregular in outline and variable in thickness. Conidiomata sporodochioid with basal stroma. Conidiophores irregularly branched, septate, hyaline, smooth walled. Conidiogenous cells discrete, hyaline, smooth walled. Sterile hyphae arising as branches of the conidiophores, filamentous, aseptate or sparsely septate, for the most part invested in mucus. Conidia holoblastic-solitary, arising excentrically at the apex of the conidiogenous cells, naviculate, unicellular, hyaline, provided with a tapering footlike process at the base; bearing an apical , and usually a basal appendage. Apical appendage infundibuliform with a terete stem, mucoid, adhesive; basal appendage, when present, terete and mucoid, enclosing base of conidium.
TYPE ANAMORPH-SPECIES: Infundibura adhaerens Nag Raj & Kendrick.
