Sakireeta

Sakireeta Subram. & K. Ramakr., J. Indian bot. Soc. 36: 83 (1957).

 Index Fungorum number: IF 9775; Facesoffungi number: FoF 08560, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

Foliicolous. Sexual morph: Unknown. Asexual morph: Conidiomata pycnidial, aggregated, immersed, depressed, globose, mostly irregularly multilocular in a stroma, dark brown, ostiolate; wall of 3–6 layers of brown textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells hyaline, smooth, lining the inner cavity, subcylindrical to ampulliform; conidiogenesis holoblastic, lacking phialides with percurrent proliferation or periclinal thickening. Conidia subcylindrical to clavate or narrowly ellipsoid, apex obtuse, base truncate, aseptate, smooth, hyaline, granular, with apical cone-shaped appendage, which splits into up to four tentaculiform undulate appendages (adapted from Crous et al. 2015).

Type species: Sakireeta madreeya Subram. & K. Ramakr.

Notes: Sakireeta resembles Tiarosporella in having subcylindrical to clavate or narrowly ellipsoid conidia with appendages. Sakireeta is unique in having holoblastic conidiogenous cells. Sakireeta differs from Tiarosporella in having aggregated conidiomata in a stroma which is plurilocular while Tiarosporella has solitary unilocular conidiomata. Molecular markers available for Tiarosporella are ITS, LSU, SSU, BTUB, RPB2 and TEF-1.
