Abstract
Five species of the pileate polypore fungi, Ganoderma ungulatum (Polyporales, Ganodermataceae), Gloeophyllum odoratum (Gloeophyllales, Gloeophyllaceae) Heterobasidion abietinum (Russulales, Bondarzewiaceae), Osmoporus mexicanus (Gloeophyllales, Gloeophyllaceae) and Oxyporus ravidus (Hymenochaetales, Schizoporaceae) are described and illustrated on the basis of basidiocarps collected during the rainy season of years 2015-2017 from different parts of Doda district (Union Territory of Jammu and Kashmir, India). Of these, the first four species are being described and illustrated for the first time from India, whereas Oxyporus ravidus is a new record for Union Territory of Jammu and Kashmir. Being the key wood decayers, these fungi grow in association with both broad-leaved as well as conifer tree species. Of the species described, the basidiocarps of Ganoderma ungulatum were collected from Quercus sp., whereas rest of the four species were growing in association with gymnospermous wood. Among the five species described presently, Heterobasidion abietinum is a host specific polypore that grows only in association with wood of Abies spp. These polypores are responsible for different types of rot and play a significant role in the recycling of different types of material. Of the described species, Ganoderma ungulatum Heterobasidion abietinum and Oxyporus ravidus are reported to cause white rot whereas Gloeophyllum odoratum and Osmoporus mexicanus are responsible for brown rot.
Highlights
Polypores (Agaricomycetes, Basidiomycota) are characteristic in having annual to perennial, resupinate to effused-reflexed to pileate, sessile to stipitate basidiocarps
Five polypore species spread over five genera, five families and five orders of Agaricomyectes (Basidiomycota) are described from Jammu division
As a result of their exploration of the union territory previous workers have reported 40 polypore species which are presently grouped under 23 genera, 8 families and 4 orders of Agaricomycetes (Basidiomycota) [2, 3, 4, 5, 6]
Summary
Polypores (Agaricomycetes, Basidiomycota) are characteristic in having annual to perennial, resupinate to effused-reflexed to pileate, sessile to stipitate basidiocarps. These fungi have unilateral hymenium organized inside tubes which open through pores that can be circular, angular, daedaleoid, lamellate or irregular. The colour of hymenial and abhymenial surfaces varies from whitish to some shades of yellow, orange, grey, violet, blue or red. These fungi play significant role in the forest ecosystem because of their ability to secrete lignin and cellulose degrading enzymes. Besides their role in recycling of carbon, some of these fungi have been used in the traditional medicinal system [1]
