Canomyces reticulatus Rahul Sharma & Shouche so. nov.

MycoBank number: MB 829250; Index Fungorum number: IF 829250; Facesoffungi number: FoF 13279;

Genbank MK340501 (ITS), MK340502 (LSU), MK340503 (SSU) (Figs. 8 and 9)

Etymology Reticulatus—referring to the punctate- reticulate ascospores of the fungus.

Description Ascomata discrete, globose, pale cream, 300–450 lm diam. Peridial hyphae undifferentiated from vegetative hyphae, smooth walled, 1.2–3.6 lm wide. Asci globose pale brown 13–16.7 lm, 8-spored, evanescent. Ascospores unicellular, yellowish to pale brown, globose, regularly punctate-reticulate, 5.6–6.3 lm diam, mostly 18 puncta seen from surface view, 0.8–0.9 lm broad.

Asexual Morph Narrow elongate arthroconidia.

Cultures Colonies after 4 week at 28 °C on SDA (5.4–5.5 cm) circular, white, cottony flat, uniform with some sectors with sparse aerial mycelia reverse pale brown fading towards margin; on PDA (4.3 cm) circular, white with sectors having little aerial mycelia giving yellowish brown appearance due to submerged growth, reverse brown at centre fading towards margin; on OA (4.5 cm) circular, snowy white, with irregular patches, flat, reverse cream coloured with central brown spot; on CMA (2.5 cm) grossly circular, lobate, yellowish, sparse aerial mycelia with irregular rings, reverse pale brown with dark centre. At 37 °C after 16 days on SDA (2.8 cm) circular, white, cottony, flat with central raised knob, centre pale coloured, rest white, reverse pale brown, growing margin pale yellow.
