Scientific Name: | Pithomyces terricola | |||
Author: | Pithomyces terricola (Manohara Chary & Ramarao) P.M. Kirk, Trans. Br. mycol. Soc. 80: 462. 1983. |
|||
Description: | Colonies effuse, plane to floccose, pale grey brown, grey brown to dark brown; reverse brown to dark brown. Mycelium partly superficial, partly immersed, composed of branched, septate, smooth to roughened or verrucose, subhyaline to brown hyphae, 0.8-5.6 μm wide. Conidiophores micronematous or semimacronematous, simple or branched, erect or flexuous, smooth to roughened or veruculose, subhyaline to brown, 1.8-5.4 μm wide. Conidiogenous cells monoblastic, mostly terminal, rarely intercalary, integrated, sometimes proliferous percurrent. Conidia solitary fusiform to broadly fusiform or broadly ellipsoidal, mostly 5-septate, occasionally 3 or 4-septate, usually verruculose to verrucose, mid brown to brown, paler and roughened or verruculose at the both ends, 18.8-40.8 × 5.2-12.2 μm, often constricted at the septa, occasionally retaining the part of the conidiophore at the base. | |||

Note: | P. terricola is similar to other Pithomyces species, but the former species was described as having monoblastic, sometimes proliferous percurrent conidiogenous cells and longer, fusiform, 3-5 septate, roughened to verrucose, mid brown to brown conidia. The Taiwanese isolate has smaller conidia (18.8-40.8 × 5.2-12.2 μm) compared to the type spe-cies and other collections. Ellis' collection (Ellis, 1976) from pond mud in India has conidia up to 60 μm long × 17 μm wide. | |||
