Content

Description

Heterotallic (dioecious) species. It forms large (60–90 (180) microns in diameter) spherical multispore sporangia , often with a crown, first white, then darkening to dark brown, as well as sporangioli - small ovoid sporangia of 10-16 × 8-12 microns, on branched sporangiophores deprived of crowns, usually containing 3 spores. The walls of sporangia are covered with crystals of calcium oxalate. When ripening sporangia open with two wings, releasing spores. In poorer environments , large sporangia on columella predominate, with the addition of nutrients to the environment, the proportion of sporangioles increases. Sporangiospores are elliptical or spindle-shaped, 8-12 × 4-8 microns, colored, with several colorless appendages.

Chlamydospores are intercalary, widely elliptical to fusiform or irregular in shape, 13–28 × 11–20 μm.

In cultures, zigosporangia appear on the surface and inside the substrate, colored, with numerous unpainted zygospores.

The cultures are first white, then with yellow spots. Aerial mycelium is not septic, to a varying degree developed. Sporangiophores mainly on substrate mycelium.

Value

Superproducer of β- carotene and riboflavin . It was actively used to study trisporic acids formed by it during sexual reproduction.

Description History

 
Scoop Anticarsa gemmatilis

It was first described in 1914 in the 58th issue of Botanical Gazette by American mycologist Roland Thaxter . The type was isolated from the caterpillar of the scoop Anticarsia gemmatalis infected with the entomopathogen Nomuraea rileyi , collected in Florida in 1912 by Owen Francis Burger and sent to Harvard University from Gainesville by Howard Samuel Fawcett . Named after Albert Francis Blacksley for his contribution to the study of mushroom mushrooms. In particular, it was Blacksley who discovered the phenomenon of heterotallism in the mucorids.
