Species MB504459 Exophiala placitae Crous & Summerell 2007   Bibliography: Crous, P.W.; Groenewald, J.Z.; Summerell, B.A., 2007, Fungal Planet no. 17: (more info) Year of publication: 2007 Status of the name: basionym; legitimate MycoBank's opinion: currently used Classification: Fungi, Anamorphic fungi, Exophiala Obligate synonym(s): none Morphic status: Anamorph (teleomorph connection(s) unknown or not recorded) Taxonomic synonym(s): Ordered by epithet name none Descriptions: Latin diagnosis Exophialae spiniferae similis, sed conidiis majoribus, (4-)5-6 x 3-4 µm. Original description Conidiomata appearing as flat pycnothyria with a central ostiole on leaves, absorbing moisture in damp chambers, becoming globose, erumpent, medium brown, upon drying down, conidiomata again flatten to appear as black pycnothyria; inner wall consisting of pale brown toruloid hyphae; outer wall of textura epidermoidea; centrum filled with toruloid hyphae that give rise to cheroid conidia. Conidia consisting of a central, basal, globose cell, verruculose, medium brown, 5-10 µm diam, giving rise to up to 6 radiating arms of 5-8 cells (5-7 µm long), which each can form lateral branches of 2-4 narrowly ellipsoid cells, 4-5 µm long; juvenile conidia hyaline, smooth. Single conidial propagules forming black, slimy colonies that give rise to an Exophiala state. Mycelium consisting of hyaline to pale brown, smooth, branched, septate, 3-4 µm wide hyphae; superficial and submerged hyphae strongly constricted at septa, but aerial hyphae not so. Conidiogenous cells intercalary or terminal, mono or polyphialidic, loci at times appearing subdenticulate, up to 1.5 µm wide, rarely proliferating percurrently, 7-15 x 5-7 µm. Conidia hyaline, aseptate, smooth, guttulate, hyaline to pale brown, narrowly ellipsoid with obtuse apex and subtruncate base, (4-)5-6 x 3-4 µm; yeast cells common in culture. Etymology Named after its host species, Eucalyptus placita.
