Taxonomy
The species was described by T.K.A. Kumar and P. Manimohan in 2009, in the journal Mycotaxon. The type collection was made in 2004, in the Kannur District of Kerala State in India. The specific epithet babrulka is derived from the Sanskrit word for "brownish".Description
The fruit bodies of Lepiota babruka have caps up to wide, which are initially broadly convex before flattening out in age, usually developing a shallow umbo. The cap color is brown, and it is covered with small, darker brown, pyramid-shaped scales. The cap margin, initially curved inward before straightening out in maturity, becomes cracked in age. The gills are free from attachment to the stem. At first, they are white, but later develop yellowish tones. They are crowded together, and have 3–4 tiers of lamellulae. The edges of the gills are the same colors as the gill face, and are fringed if viewed with a hand lens. The cylindrical, hollow, stem measure long and 2 mm thick, and roughly the same width throughout. Its color is initially brown before darkening, and the surface is fibrillose. A whitish, membranous ring is present on the upper portion of the stem in young fruit bodies, but it does not last for long. The flesh is thin, yellowish-white, and lacks any distinctive odor.The spores have a roughly elliptical shape, and dimensions of 4.5–7 by 3–4 μm. They are thick-walled, smooth, hyaline, and contain refractive oil droplets. The basidia are club-shaped, four-spored with sterigmata up to 3 μm long, and measure 10–17 by 6–8 μm. The cheilocystidia are plentiful, thin-walled, and measure 13–34 by 10–20 μm; there are no pleurocystidia.
