Marasmiellus Murrill

The genus is saprobic on twigs, canes, small logs, and litter; growing alone, scattered, or growing in colonies. The specimens were collected from Karnala Bird Sanctuary, Manikgad, Amboli and Maharashtra Nature Park.

Morphology:

Pileus 3-20 mm diam., semicircular to dimidiate; surface yellowish white near attachment, white elsewhere, thin; margin translucent straite, entire. Gills arising from the attachment point, distant, thin, often furcated, anastomosing near attachment. Stipe almost absent to reduced to 1-2 × 1 mm. Annulus absent. Volva absent.

Review of patents

1. 1.5-substituted picolinic acid compounds were produced by fermenting Marasmiellus, which then used in tumor necrosis factor mediated diseases[1].
2. 2.A composition in which troyanus was used as an inoculum for remediating polluted environment[2].

Review of publications

1. 1.Marasmiellus celebanticus, collected in the coastal area of northeast Spain, was illustrated and described as a new species on the basis of morphological features and ITS sequence analysis[3].
2. 2.Two new hirsutane sesquiterpenes were isolated from cultures of the Marasmiellus[4].
3. 3.Three new unusual sesquiterpenes (1–3) were isolated from troyanus and their structure is elucidated using various techniques[5].
4. 4.Antioxidant properties of methanol extracts of Marasmiellus were evaluated[6].
5. 5.Chemical investigations were carried out using the cultures of ramealis[7].
6. 6.Two new compounds isolated from the cultures of ramealis were evaluated for inhibitory activity against acetylcholine esterase[8].
