Please answer the following question: Information:  - Craterellus is a genus of generally edible fungi similar to the closely related chanterelles, with some new species recently moved from the latter to the former. Both groups lack true gills on the underside of their caps, though they often have gill-like wrinkles and ridges.  - Craterellus lutescens , or Cantharellus lutescens or Cantharellus xanthopus or Cantharellus aurora , commonly known as Yellow Foot , is a species of mushroom . It is closely related to Craterellus tubaeformis . Its hymenium is usually orange or white , whereas the hymenium of C. tubaeformis is grey . C. lutescens is also usually found in wetlands .  - A hymenophore refers to the hymenium-bearing structure of a fungal fruiting body. Hymenophores can be smooth surfaces, lamellae, folds, tubes, or teeth.  - Craterellus tubaeformis (formerly "Cantharellus tubaeformis") is an edible fungus, also known as Yellowfoot, winter mushroom, or Funnel Chanterelle. It is mycorrhizal, forming symbiotic associations with plants, making it very challenging to cultivate. It is smaller than the golden chanterelle ("Cantharellus cibarius") and has a dark brown cap with paler gills and a hollow yellow stem. "C. tubaeformis" tastes stronger but less fruity than the golden chanterelle. It has a very distinctive smokey, peppery taste when raw. It grows in temperate and cold parts of Northern America and Europe, including Scandinavia, Finland, Russia, and the British Isles, as well as in the Himalayas in Asia, including Assam, in the central parts of the Indian Subcontinent , and in Thailand  - The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia (basidiomycetes) or paraphyses (ascomycetes). Cystidia are often important for microscopic identification. The subhymenium consists of the supportive hyphae from which the cells of the hymenium grow, beneath which is the hymenophoral trama, the hyphae that make up the mass of the hymenophore.    After reading the paragraphs above, we are interested in knowing the entity with which 'craterellus lutescens' exhibits the relationship of 'hymenium type'. Find the answer from the choices below.  Choices: - ridges  - smooth
A:
ridges
